Sex determination from skull remains101
This document summarizes methods for determining sex from skull remains. It discusses both metrical and morphological characteristics that can be used. Metrical methods examine skull measurements and use statistics like means and standard deviations to differentiate male and female skulls. Morphological methods examine traits like robustness of features, shape of the orbits, palate shape, and mandible shape. The document indicates that sex determination from skulls can be 70-95% accurate using these methods, but accuracy depends on the population and may be lower for fragmented remains or those outside the 20-55 age range.

Introduction to osteology
Osteology, derived from the from Greek ὀστέον (ostéon) 'bones', and λόγος (logos) 'study', is the scientific study of bones, practised by osteologists. A subdiscipline of anatomy, anthropology, and paleontology, osteology is the detailed study of the structure of bones, skeletal elements, teeth, microbone morphology, function, disease, pathology, the process of ossification (from cartilaginous molds), and the resistance and hardness of bones (biophysics).[1]
Osteologists frequently work in the public and private sector as consultants for museums, scientists for research laboratories, scientists for medical investigations and/or for companies producing osteological reproductions in an academic context.
Osteology and osteologists should not be confused with osteopathy and its practitioners, osteopaths.
Division of human skeleton system
The human skeleton is divided into two main divisions - the axial skeleton and appendicular skeleton. The axial skeleton forms the central axis and includes the skull, vertebral column, and thoracic cage. It contains a total of 80 bones. The appendicular skeleton includes all bones of the upper and lower limbs and the shoulder and pelvic girdles that attach each limb to the axial skeleton. It contains a total of 126 bones. Together these two divisions make up the 206 total bones in the adult human skeleton.
General osteology
The skeletal system is composed of 206 bones that serve important biological and mechanical functions. The axial skeleton includes 80 bones that form the axis of the body and protect organs like the brain, while the appendicular skeleton has 126 bones that make up the limbs and their attachments. Bones are living organs composed of compact and spongy tissues, cells like osteoblasts and osteoclasts, and minerals including calcium that provide structure and strength. The skeleton supports the body, protects organs, allows for movement through leverage, and stores minerals and produces blood cells in the bone marrow. Bones are classified by their shapes including tubular, flat, irregular, and sesamoid.
Sex Determination
The document discusses how to determine sex from human skeletal remains. Key indicators of sex include the shape of the pelvis, skull, and long bones. The pelvis is the most accurate indicator, with features like the sciatic notch, subpubic angle, and pelvic inlet differing between males and females in ways related to reproduction and childbirth. The skull also displays sexual dimorphism through traits such as the supraorbital ridge, orbits, and mandible shape. Measurements of bones can provide clues as well.
Somatometric measurements generally used for identification.pptx
Somatometric measurements refer to measurements taken on the living human body using well-defined anatomical landmarks. They are useful for identification, designing equipment, assessing nutrition, and studying populations. Measurements are generally taken with minimal clothing in a standardized position using instruments like calipers and tapes. Over 29 measurements are outlined covering dimensions of the head, face, nose, hands, feet, and various girths. Landmarks and techniques are provided to ensure accuracy. Ratios of measurements are also calculated as somatometric indices for identification and comparison across groups.

Craniometry.ppt
This document discusses craniometry and cephalometry, which are techniques used to measure the skull and head. Craniometry involves measuring the dry skull after removing soft tissues, while cephalometry measures the head with soft tissues intact. Both are branches of physical anthropology. Key craniometric and cephalometric points are identified which are landmarks used to take measurements of the skull, face, and palate. Various indices are also described, such as cephalic index which categorizes head shape, and facial and palatomaxillary indices relating to face and palate width. Cephalometry is also used in dentistry and orthodontics to analyze teeth, jaws, and skull relationships to inform treatment.
Sex determination using anthropometric methods
This document summarizes methods for determining sex from skeletal remains using anthropometric analysis. It outlines key sexual dimorphisms in the skull, pelvis, and long bones that can be used to identify whether remains are from a male or female. For the skull, traits like robustness, orbital shape, and mastoid process size can indicate sex. In the pelvis, characteristics such as the subpubic angle, sciatic notch width, and pubic arch shape provide clues. Measurements and morphological features of long bones like the femur, tibia, humerus and ulna also differ between males and females. Anthropologists can use these multiple lines of evidence from the skeleton to assign sex with 90-95%
Growth of bone
The document discusses the process of ossification where cartilage is changed to bone during human development. It explains that ossification is impacted by three key cells: osteoblasts, which build bone; osteocytes, which are trapped osteoblasts that give bone its star-shaped appearance; and osteoclasts, which break down old or damaged bone. The document also outlines factors like nutrition, vitamins, hormones, and growth that influence bone growth and remodeling throughout life.
Confirmatory Test for Semen identification
Seminal fluid is a complex mixture of secretions from at least four male urogenital glands. The seminal vesicle gland contributes approximately 60% to this mixture, the prostate gland contributes approximately 30%, and the combined contribution of the epididymis and bulbourethral glands account for the remaining 10%
Confirmatory Tests for semen:
1- The Christmas Tree Stain: The most reliable confirmation for the presence of semen is the positive visual identification of sperm cells (or spermatozoa) using the Christmas tree stain.
role of forensic anthropologist
The document discusses the role and responsibilities of forensic anthropologists. It begins by defining forensic anthropology as the application of physical anthropology to legal investigations. It then outlines some of the main duties of forensic anthropologists, which include identifying remains, determining cause and manner of death, estimating time since death, and reconstructing facial features to help with identifications. Forensic anthropologists play an important role in investigations by using skeletal analysis to establish biological profiles and help solve crimes.
Study of Soil and Paint
This document provides information about soils and paints. It defines soil as a mixture of organic matter, minerals, gases, liquids, and organisms that support life. The four main components of soil are identified as minerals, water, organic matter, and gases. Key soil types like sand, silt, clay and loam are described. Methods for analyzing soils like determining moisture content and particle size distribution are outlined. The document also defines paint as a liquid that converts to a solid film after application. The main components of paint are identified as pigments, binders, liquids, and additives. Common types of paints like water-based and oil-based are described. Forensic analysis methods for soils and paints are mentioned
Skeleton
The human skeleton is made up of 206 bones that provide structure, protection, movement, and more. It is divided into the axial skeleton which includes the skull, vertebral column, rib cage, and hyoid bone, and the appendicular skeleton which connects to the axial skeleton through girdles and includes the upper and lower limbs. The skeleton allows for movement, protects organs, provides sites for muscle attachment, stores minerals, and produces blood cells.
7 Forensic Science Powerpoint Chapter 07 Forensic Anthropology
The document discusses the role and techniques of forensic anthropology. It covers how forensic anthropologists examine human remains to develop a biological profile of victims and help with identification. They assess bones for characteristics like age, sex, ancestry and compare to records. Forensic anthropologists also study taphonomy and trauma to reconstruct events. Their expertise complements forensic pathologists in investigations.
Formation of Bone
Bone is a specialized connective tissue composed of cells, fibers, and minerals. It forms through two processes: endochondral ossification and intramembranous ossification. Endochondral ossification involves cartilage models that are replaced by bone, forming long bones and portions of flat bones. It begins in the second month of development. Intramembranous ossification involves mesenchymal cells directly forming bone, without a cartilage intermediate, forming bones like the skull and clavicle. Bone growth is regulated by hormones like growth hormone and sex hormones. Common bone diseases include osteogenesis imperfecta and achondroplasia.
Introduction to osteology
Osteology is the study of bones. Bones provide structure, protection, movement, mineral storage, blood cell formation, and energy storage. Bone tissue consists of cells within an organic collagen-rich extracellular matrix as well as an inorganic mineral component. Cortical bone forms the dense outer layer of long bones and has concentric osteons. Cancellous or spongy bone is found at the ends of long bones and in flat and irregular bones. Bones experience both compression and tension forces and have adapted structures like osteons and layered lamellae to withstand these stresses.
Ossification (Intracartilaginous and Intramembranous)
Ossification is the process of bone formation. There are two types of ossification: intramembranous ossification and intracartilaginous (endochondral) ossification. In intramembranous ossification, bone is laid down directly in fibrous membranes by osteoblasts differentiating from mesenchymal cells. Bones formed this way include the skull and clavicle. In intracartilaginous ossification, a cartilaginous model is first formed and then replaced by bone. Long bones develop through this process, with osteoblasts eroding and replacing the cartilage matrix.
1.introduction to human anatomy
Anatomy is the study of structure, while physiology is the study of function. Anatomy can be studied at both the macroscopic and microscopic levels. Microscopic anatomy includes histology, the study of tissues, and cytology, the study of cells. The human body is composed of organ systems that work together, including the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems. Each system contains different components that allow it to carry out its specialized functions necessary for maintaining life.
Cartilage & bones
Cartilage and bone are types of connective tissue that provide structure and support. There are three main types of cartilage - hyaline, elastic, and fibrocartilage - which are located in various parts of the body like joints, ears, and larynx. Cartilage is made of chondrocytes in an extracellular matrix. Bone develops from cartilage through endochondral ossification and forms directly from mesenchymal tissue through intramembranous ossification. Bones have compact bone, spongy bone, and are remodeled through the actions of osteoblasts and osteoclasts. Common bone disorders occur due to defects in collagen, calcification, or excessive bone turnover.
The Musculoskeletal System
The musculoskeletal system provides structure, movement, and protection to the human body. It is composed of bones, cartilage, tendons, ligaments, joints, and muscles. Bones provide structure and store minerals, muscles allow movement by contracting and relaxing, and joints connect bones to facilitate motion. Together, these components form a complex system that is essential for human movement and survival.
Body fluids
This document discusses various body fluids and the presumptive and confirmatory tests used to identify them at a crime scene. It outlines tests for blood, saliva, urine, semen, fecal stains, and sweat. For blood, tests detect hemoglobin or heme compounds, including the luminol, fluorescein, phenolphthalein, Teichmann, and Takayama tests. Saliva tests identify the enzyme amylase, including using Phadebas tablets. Urine tests detect creatinine or urea. Semen tests identify acid phosphatase or prostate antigens. Fecal tests detect bilirubin breakdown products. And sweat can be identified using crystal violet dye interaction.
Embalming diagnosis and m.l aspect
The document discusses different methods of embalming a dead body, including arterial embalming, cavity embalming, and surface embalming. It describes the composition of embalming fluids and the process of injecting the fluids into the body. Embalming preserves the body and prevents decomposition by coagulating proteins, fixing tissues, and bleaching and hardening organs. It must be done within 6 hours of death for best results. Embalming has medical, legal, and transportation purposes but can complicate autopsy and toxicology analyses.
Classification of bones and Anatomy of a long bone
Bones can be classified in several ways, including by shape, location, function, and microscopic features. Long bones can be divided into four main parts: the epiphysis, physis, metaphysis, and diaphysis. The epiphysis contains pressure-bearing cartilage and bone at the end of the bone. Between the epiphysis and diaphysis is the physis or epiphyseal plate, which is responsible for longitudinal bone growth. The metaphysis is the transitional zone between the epiphysis and diaphysis. The diaphysis forms the tubular shaft in the center of the bone. Understanding bone classification and anatomy is important for disease diagnosis and treatment.
Sex determination from skull and mandible
This document discusses how to determine sex from the human skull. Several features of the skull are sexually dimorphic and can indicate if the skull belonged to a male or female. These features include the supraorbital ridges, orbits, glabella, zygomatic arches, mastoid process, and mandible. In general, male skulls tend to be larger and more robust than female skulls. Each of the sexually dimorphic features are described in terms of typical male and female characteristics. The document also discusses using metrics of the mandible alone to determine sex when the full skull is not available.
Examination of Blood
This document discusses the examination of blood in forensic science. It outlines the key components of blood, including erythrocytes, leukocytes, and platelets. It also describes several preliminary tests that can identify the presence of blood, such as the Kastlemeyer test, LMG test, and luminol test. Two confirmatory tests are also discussed: the Takayama test and Tiechmann's test. The forensic significance of blood evidence is explained, noting how blood can link a victim to a suspect, reveal bloodstain patterns, and allow individualization through DNA profiling.

Key events and figures mentioned include the first use of forensic techniques in China in 1248, the contributions of Ambroise Pare in the 16th century, the founding of toxicology and ballistics analysis, and the pioneering work of Bertillon, Gross, Locard and others in the late 19th/early 20th centuries. The document also outlines the subfields of forensic science and bodies that foster its development.Human body & Musculoskeletal system.pdf
Throughout history, the symbol of the skull and crossbones has served as a representation of mortality, likely owing to the fact that following death and decay, bones are the sole remnants. Many individuals perceive bones as inert, desiccated, and fragile. While these attributes accurately portray the bones of a preserved skeleton, the bones within a living human being are profoundly alive. Living bones exhibit strength and flexibility, serving as the primary components of the skeletal system.
Skeletal system
Bone tissues makes up about 18% of the total human body weight. The skeletal system supports and protects the body while giving it shape and form.

The skeleton provides structure and protection to the body and facilitates movement through its arrangement of bones and joints. It consists of 206 bones organized into the axial skeleton which protects organs, and the appendicular skeleton in the limbs. Bones can be classified as long, short, flat, irregular or sesamoid depending on their shape. Joints connect bones and can be immovable, allow slight movement or full movement, held together by fibrous, cartilaginous or synovial tissues. Together, the skeleton, muscles and nerves work in an integrated system to enable movement of the body.

Bones, Joints, and the Architecture of Movement: Exploring the Skeletal System
Title: Bones, Joints, and the Architecture of Movement: Exploring the Skeletal System
Introduction:
Welcome to our engaging SlideShare presentation on the Skeletal System & Joints, where we embark on a fascinating exploration of the framework that supports our bodies and facilitates movement. Join us as we delve into the intricate world of bones, joints, and the dynamic interplay that shapes our mobility and stability.
The skeletal system serves as the foundation of our anatomy, providing structural support, protection for vital organs, and a framework for locomotion. Comprised of bones, cartilage, ligaments, and tendons, this complex system forms the structural scaffold upon which our bodies are built.
In this presentation, we'll take a closer look at the anatomy of bones, from their composition and classification to their roles in mineral storage and blood cell production. Through detailed illustrations and interactive diagrams, we'll explore the dynamic nature of bone remodeling and the factors that influence bone health and density.
But bones alone do not account for the versatility of human movement. Joints, the articulations where two or more bones meet, play a crucial role in facilitating motion and absorbing impact. From synovial joints like the knee and shoulder to fibrous and cartilaginous joints, we'll unravel the mechanics of joint structure and function.
Together, the skeletal system and joints form a complex network that enables us to walk, run, jump, and perform a myriad of daily activities. Whether you're a student studying anatomy, a fitness enthusiast seeking to optimize performance, or simply curious about the mechanics of the human body, our presentation offers valuable insights into the wonders of the skeletal system and joints.
Join us as we embark on a journey through the bony landmarks and articulations that define our physical form and discover the intricate architecture of movement hidden beneath our skin.

TRAP CASES
A trap is a procedure used to catch a public servant accepting a bribe. The complainant files a case stating a public servant demanded a bribe. An investigation is done and if the complaint is genuine, permission is given to lay a trap. For the trap, the complainant is given money coated in phenolphthalein powder to pay the bribe. Officers witness the exchange and arrest the public servant if a phenolphthalein test turns positive, indicating they handled the money. A successful trap provides strong evidence of guilt in corruption cases against public servants.
TMB test
This document describes the tetramethylbenzidine (TMB) presumptive test for detecting blood. The TMB test works by catalyzing the peroxidase-like activity of hemoglobin in blood. When heme in blood reacts with TMB in the presence of hydrogen peroxide, it causes TMB to oxidize and turn blue-green. The TMB test can detect blood dilutions up to 1:1000,000 and provides results within 20 seconds. It is a sensitive, easy and economical test for detecting blood, but uses corrosive reagents and lacks specificity for differentiating blood from other substances that may also cause color changes.
Special types of crime scenes Part-2
1) The document discusses the role of forensic experts in investigating mass disasters and terrorist attacks. It covers types of disasters, management of disaster sites, and the roles of forensic pathologists and other experts.
2) Key responsibilities of forensic teams include identifying victims through means like DNA, dental records, and fingerprints. They also work to determine the cause of death and examine disaster sites for clues.
3) An example discussed is the 1993 Mumbai bombings, where RDX explosives were used in vehicles to kill over 100 people across 12 sites. Forensic analysis of debris and other evidence helped investigate the terrorist attacks.
Special types of crime scenes Part-1.pptx
- Crime scene investigation involves collecting and analyzing evidence from the location where a crime occurred. Biological evidence like blood, as well as latent prints, digital evidence, trace evidence and more may be collected.
- The type of evidence collected depends on the crime. For example, a burglary may involve collecting trace evidence and DNA evidence from points of entry and likely contact areas.
- How a crime scene is processed generally follows seven steps: establishing security; documenting the scene; collecting, packaging and preserving evidence. The most probative evidence is sent to forensic laboratories for detailed examination and analysis.
Scope of Cyber forensics
This document discusses the scope of cyber forensics. It defines cyber forensics as the process of extracting digital evidence from cyber crimes while maintaining a documented chain of custody. It describes the types of cyber forensics like network, email, mobile device forensics. It outlines the key steps cyber forensics experts follow: identification, preservation, analysis and documentation of digital evidence found, and presentation in court. Finally, it discusses the importance of cyber forensics in solving cyber and real-world crimes and ensuring integrity of digital evidence.
Principles of fingerprints
This document discusses the principles of fingerprints. It begins by introducing fingerprints, noting that they are unique ridge patterns on fingers that remain unchanged throughout life, making them useful for identification. It then describes the three main fingerprint types - arch, loop, and whorl. The key principles of fingerprints are that they are individual, permanent, universal, and classifiable. Fingerprints are individual due to their unique ridge patterns. They remain permanent from a young age to old age. They are universal across all humans. And their patterns can be classified into categories. The document concludes that these principles make fingerprints forensically significant for identifying criminals and determining a suspect's presence at a crime scene.
porous and non-porous surface
This document discusses the differences between porous and non-porous surfaces for fingerprint development. Fingerprints deposited on non-porous surfaces like glass or plastic do not absorb residues, which can be developed using powder methods or cyanoacrylate fuming. Fingerprints on porous surfaces like paper or cardboard allow residue absorption, requiring chemical methods like ninhydrin or iodine fuming to react with residues below the surface. Key differences are how long residues remain, appropriate development techniques, and advantages/disadvantages of each method for different surface types.
Physical Examination Of Tyre Marks
This document discusses the physical examination of tyre marks in forensic investigations. It describes the different types of tyre marks including yaw marks, scrub marks, and skid marks. It outlines the characteristics and identification process for tyre marks, including width, tread pattern, and circumstances. The document explains that tyre marks can be photographed, casted, or examined at a crime scene and provides their forensic significance in helping to identify vehicles and tracing criminal activity.
PAINT EVIDENCE COLLECTION
Paints are very common evidence found in hit and run cases, burglary cases and many other cases. The collection of paint evidence has been explained in this presentation
Microcrystalline Test for drugs
This document discusses microcrystalline testing for drugs. The test identifies specific drugs based on the unique shape and color of crystals formed when a drug sample is mixed with a specific reagent under a microscope. An example is provided where cocaine produces X-shaped crystals when reacted with gold chloride. The test has advantages of being cheap, simple, rapid and sensitive. However, it requires an expert to perform and interpret and can destroy important drug samples.
Introduction to PCR technique
This document introduces the polymerase chain reaction (PCR) technique. It explains that PCR is used to amplify a small segment of DNA across many orders of magnitude, generating thousands to millions of copies of a particular sequence. The principle of PCR involves denaturing DNA, annealing primers to the DNA, and extending the DNA via polymerase. Key instrumentation is used to perform PCR. The document concludes that PCR has significant forensic applications like identifying human remains and developing genetic fingerprints from crime scene samples.
History OF DNA typing
This document provides an overview of the history of forensic DNA typing. It discusses how in 1980, Ray White described the first polymorphic RFLP marker and in 1985, Alec Jeffreys discovered multilocus VNTR probes. It then outlines some of the major developments in DNA typing techniques between 1985-1998, including the first use of PCR in 1985 and the FBI starting their DNA casework in 1988. The document also provides brief descriptions of the principles, steps, techniques, advantages, disadvantages and applications of DNA typing.

FORENSIC BIOMETRIC
Biometrics refers to the automatic identification of a person based on physiological or behavioral characteristics. Passwords, PINs, and keys are not very reliable for identification since they can be forgotten, shared, stolen, or easily guessed. Biometric identification uses unique physical traits like fingerprints, iris scans, voice recognition, or hand geometry that cannot be lost or shared to reliably identify individuals. As biometric technology advances, it may replace traditional identification methods and provide more secure access to sensitive information, banking, government systems, and commercial applications.
fingerprint characteristics
This document summarizes the key characteristics of fingerprints. It discusses how fingerprints develop in the womb, the three main fingerprint patterns (arch, loop, and whorl), and the ridge and minutia details that make each fingerprint unique. It also outlines the three main types of fingerprints that can be found at crime scenes: patent prints formed through transfers of colored materials, latent prints through sweat or oil, and plastic prints on pliable surfaces.
Fiber & Examination of fibers
Fibers are associative evidence that can link a suspect to a crime scene based on the principle of exchange. Fibers may be important evidence in crimes involving personal contact and should be collected visually using clean tools or tape lifting and preserved in paper envelopes. Key characteristics of fibers examined include diameter, cross section, color, and location. Analysis methods include microscopy and chemical analysis to determine if a questioned fiber belongs to a known fabric. Fibers can indicate an individual's presence but are not unique like fingerprints or DNA.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Introduction to Human Osteology Part 1
- 2. Made by: Dr Pankti Patel M.Sc. Forensic Odontology Volunteer at AFRS
- 3. What is Osteology? Types of human skeleton Functions of bones Classification of bones
- 4. Skeleton- The human body is made up of several bones and cartilages, which together forms the human skeleton. Endoskeleton- Skeleton found internally in the body. Exoskeleton- Skeleton found outside the body. In humans, this is very rudimentary pertaining to nails and enamel of the teeth. Osteology- The science concerned with the study of skeleton is called osteology. An adult human skeletal system is made up of total 206 bones. There are two types of skeleton: Axial Appendicular
- 5. These bones form the axis of the body and support organs of head, neck and trunk. Total 80 bones form the axial skeleton which include: -Skull (Cranial bones and facial bones- 28) -Auditory ossicles (6) -Hyoid bone (1) -Vertebral column (26) -Thoracic cage (Sternum -1 , ribs -24)
- 6. Total 126 bones of upper limb (64) and lower limb (62) along with bony girdles that achor the appendages with the axial skeleton Upper limb- Humerus, ulna, radius, carpals, metacarpals and phalanges of hand Lower limb- Femur, tibia, fibula, tarsals, metatarsals and phalanges of feet Shoulder girdle- Scapula and clavicle Pelvic girdle- Sacrum,ilium, ischium and pubis
- 8. Forms the body framework to provide shape and form to the body. Supports and transmits weight of the body Provides framework for locomotion and articulation. Gives attachment to muscles and ligaments. Provides protection to vital internal organs like brain, lungs and heart. Storage of calcium Blood cell formation within bone marrow
- 9. According to position: -Axial - Appendicular According to size and shape : -Long bones – act as levers for movements and locomotion. For ex: humerus, ulna, radius, femur, tibia and fibula. -Short long bones- same as above but miniature in size. For ex: metacarpals, metatarsals and phalanges. -Short bones- small, polyhedral and cuboidal like. They provide strength and compactness but limited range of motion. For ex: Carpals and tarsals.
- 10. -Flat bones - Expanded and plate like flat. Protect vital organs and areas for muscular attachment. For ex: Sternum, scapula, ribs, parietal and frontal bones. -Irregular bones- do not fit in any of the above categories. For ex: Vertebrae, some skull bones -Pneumatic bones- flat and irregular with hollow space within which is filled with air. For ex: maxilla, mastoid, ethmoid -Sesamoid bones- Seed like. They are nodules of bones which develop in some tendons and ossify after birth. They protect tendon from stress and wear. For ex: Patella (largest sesamoid bone, develops from quadriceps femoris tendon)
- 11. According to gross structure: a. Compact (lamellar) bone- outer cortical part of long bones. b. Spongy (cancellous) bone- inner part of bone that is less hard seen in flat bones, irregular bones and ends of long bones. c. Diploic bone- consists of inner and outer covering of compact bone with intervening porous layer of spongy bone. • According to development: a) Membranous/ ectochondrial bones- which develop from the membrane b) Cartilaginous/ endochondrial bones- which develop from the cartilage. Seen in most of cranial bones.
