This document summarizes key aspects of skeletal physiology:
- It describes the four types of bones and the typical structures of long bones, including the diaphysis, epiphyses, articular cartilage, periosteum, medullary cavity, and endosteum.
- It also discusses the major bone cells (osteoblasts, osteoclasts, osteocytes), the Haversian system, bone matrix composition, and methods of measuring bone mineral density.
- Additional sections cover bone formation through intramembranous and endochondral ossification, fracture repair, cartilage types, bone growth, joint classification, and homeostasis functions of bones.
The document discusses skeletal physiology, including the functions of bones, bone homeostasis, ossification processes, fracture repair, bone cell types, and classifications of joints. It addresses five functions of bones: support, protection, movement, mineral storage, and hematopoiesis. It describes the two types of ossification - intramembranous and endochondral - and the phases of fracture repair. Key bone cell types are identified as osteoblasts, osteoclasts, and osteocytes. Joints are classified based on both structure and function.
This document discusses the classification and structure of joints in the human body. It describes three types of joints: fibrous joints, cartilaginous joints, and synovial joints. Synovial joints are the most common and include ball-and-socket joints, hinge joints, pivot joints, gliding joints, condyloid joints, and saddle joints. These joints are characterized by an articular capsule containing synovial fluid that lubricates and nourishes the joint structures to allow movement.
The document discusses how cancer treatments can damage bone marrow and prevent blood cell production, how osteoporosis weakens bones by inhibiting calcium's role in bone growth, and how epiphyseal plate fractures are more common in children and young adults as the plates at the ends of long bones are still hardening during growth. Proper nutrition is also highlighted as important for maintaining strong bones in adults.
This document discusses the different types of joints in the human body. It begins by defining a joint and classifying joints by function and structure. The three main types by function are synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable). The three main types by structure are fibrous, cartilaginous, and synovial joints. It then provides details on the different types of synovial joints and examples of various joints in the body like the shoulder, elbow, hip, knee, ankle joints. It concludes with a brief description of bursae and fontanels.
1) There are three main types of joints in the body: fibrous joints, cartilaginous joints, and synovial joints.
2) Fibrous joints are joined by connective tissue, cartilaginous joints are joined by cartilage, and synovial joints contain a fluid-filled cavity allowing for movement.
3) Important synovial joints include the ball and socket shoulder and hip joints, the hinge elbow and knee joints, and gliding joints between vertebrae. These joints are important for movement and have structures like cartilage, ligaments, and synovial fluid that allow the bones to articulate smoothly.
The document discusses the gross and microscopic anatomy of long bones. Grossly, long bones are composed of a diaphysis or shaft made of compact bone covered by periosteum. The epiphyses at the ends are made of thin compact bone enclosing spongy bone. Articular cartilage provides a smooth, slippery joint surface. Microscopically, osteocytes are found in lacunae surrounding central haversian canals, communicating through canaliculi and perforating canals.
This document provides an overview of bone tissue and the skeletal system. It discusses the key functions of bone, the major tissues of the skeletal system including bone, cartilage, periosteum and endosteum. It describes the structure of long bones and the histology of compact and spongy bone. Bone formation occurs through two processes, intramembranous and endochondral ossification. Bone growth and remodeling requires balanced activity of osteoblasts and osteoclasts and is regulated by minerals, vitamins and hormones like PTH, calcitonin, growth hormone and sex hormones. Calcium homeostasis in the body is maintained through hormonal control of calcium levels in the blood and bone.
The musculoskeletal system allows for movement of the body and is comprised of bones, muscles, cartilage, tendons and ligaments. The skeletal system provides structure and protection to the body through bones and bone marrow. Bones provide support, protect organs, allow for movement through muscles attaching to them, and store minerals. There are over 200 bones in the human body that make up the axial skeleton (skull, spine, ribcage) and appendicular skeleton (limbs and their attachments).

Macroscopic & Microscopic Structure of Skeletal SystemSado Anatomist
The document discusses the skeletal system at both the macroscopic and microscopic levels. It describes the components of the skeletal system as bone, cartilage, tendons, and ligaments. It then explains the main functions of bones and the skeletal system, which include support, protection, assistance in movement, mineral homeostasis, blood cell production, and triglyceride storage. The document proceeds to classify and describe the different types of bones based on their shapes and locations. Finally, it examines the detailed microscopic structure of long bones and bone tissue.
This document discusses the structure and classification of joints in the human body. It begins by defining arthrology as the study of joints, which connect two or more bones. Joints are classified as either synarthroses (immovable joints) or diarthroses (freely movable joints). Diarthroses, also called synovial joints, are further classified based on their plane of movement, number of articulating bones, and shape of the articulating surfaces. Key features of synovial joints include the articular capsule, articular cartilage, synovial fluid, ligaments, and associated structures like menisci and bursae. The document provides detailed descriptions of these structures and their functions.
This document discusses the skeletal system and different types of joints. It begins by defining a joint as the connection between two or more bones, and notes their functions of binding parts of the skeleton together and enabling movement. It then describes three classifications of joints: functional (based on movement), structural (based on connecting material), and synovial joints (which have a fluid-filled cavity). Several examples of each type of joint are provided, along with diagrams of their structures.

The document summarizes the skeletal system, including its main components, functions, classification of bones, bone structure, development and growth. It discusses the two divisions of the skeleton - axial and appendicular. It also describes the different types of joints, their classification and movements allowed. The skeletal system provides structure and support to the body, protects internal organs, allows movement, stores minerals and enables blood cell formation. It consists of bones organized into an internal axial skeleton and external appendages.
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.
Cartilage is a type of connective tissue found in joints that provides structure and elasticity. There are three main types of cartilage - hyaline, elastic, and fibrocartilage. Joints allow bones to articulate and move. The two main types are diarthrodial synovial joints, which have a joint cavity and allow free movement, and synarthrodial joints, which are solid joints with little to no movement. Common synovial joints include hinge joints, pivot joints, condyloid joints, saddle joints, and ball and socket joints. Cartilage, synovial fluid, menisci, and other structures work together to provide support, lubrication, and smooth movement between bones.
There are four main types of bones: long bones, short bones, flat bones, and irregular bones. Long bones have a shaft and two articulating ends, examples being the femur and humerus. Short bones are cube-shaped like wrist and ankle bones. Flat bones are broad and thin, found in the skull, shoulder blades, ribs, and sternum. Irregular bones come in various shapes and sizes, like the patella. Bones are made up of cells, fibers, and extracellular matrix. They provide structure, protection, movement, mineral storage, and blood cell formation to the body. Bone formation occurs through two processes - intramembranous ossification which forms flat bones, and endochondral oss
There are three main types of joints in the body: fibrous joints, cartilaginous joints, and synovial joints. Joints can also be classified functionally as immovable (synarthrosis), slightly movable (amphiarthrosis), or freely movable (diarthrosis). The classification is based on the degree of movement allowed. Examples of each type of joint and their roles in the body are described. Joints form during embryonic development from mesenchymal tissue and allow bones to articulate and provide both stability and mobility.
Bones provide support, protection, movement, mineral storage, and blood cell formation. With aging, bones become thinner and more porous due to increased bone absorption. This bone loss leads to loss of height and increased curvature of the spine and joints, contributing to osteoporosis.
Fibrous joints are held together by connective tissue with no cavity present, and are either slightly mobile or immobile. Synovial joints contain synovial fluid and are freely movable, consisting of hyaline cartilage covering bone ends, a synovial membrane surrounding the joint cavity, and a fibrous capsule made of ligaments. Synovial joints allow for gliding, hinge, pivot, condyloid, saddle, and ball-and-socket movements. Long bones have a shaft and two expanded ends, short bones are any shape, flat bones resemble shallow plates, and irregular bones have completely irregular shapes.
Joints, or articulations, are functional connections between bones that allow for movement. There are three main classifications of joints based on their structure and movement capabilities. Fibrous joints are immovable and connect bones using dense connective tissue. Cartilaginous joints have slight movement and connect bones with cartilage. Synovial joints are fully movable and contain synovial fluid within a joint cavity to facilitate movement. Common synovial joints include ball-and-socket joints, hinge joints, and gliding joints.
The document discusses bones and cartilages. It describes the structure and types of cartilage, including elastic, fibrocartilage, and hyaline cartilage. It then covers the gross structure of bones, including compact and cancellous bone. Bone cells like osteoblasts, osteoclasts and osteocytes are also discussed. The functions of bone include mechanical support, mineral storage, and endocrine functions. Bone formation occurs through endochondral and intramembranous ossification. The document also outlines different types of bones such as long, short, flat, and irregular bones.
The document discusses skeletal physiology, including the four types of bones, structures of long bones, constituents of bone tissue, cells found in bones, functions of bones, and bone development. It also covers cartilage structure and types, bone and cartilage growth, bone fracture repair, and joints. Key points include that long bones have a diaphysis and epiphyses, bones provide support, protection, movement, mineral storage, and blood cell formation. Cartilage includes hyaline, elastic, and fibrocartilage. Bones and cartilage both grow through cell activity but cartilage also grows through the deposition of new matrix.
The document discusses the skeletal system, including:
1. The functions of bone such as protection, movement, and blood production.
2. Methods of classifying bones by shape (long, short, flat), structure (compact, spongy), and location (axial, appendicular).
3. The structure of long bones including the diaphysis, epiphysis, and growth plates.
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.
Bones are traditionally classified as long, short, flat, or mixed based on appearance. However, this classification does not account for differences in structure, function, and development between bones of the same group. A more accurate classification should consider form, function, and development. The document then presents an alternative classification system that divides bones into tubular, spongy, flat, and mixed groups based on their composition, functions in the skeleton, and locations.
Cartilage and bone are connective tissues that provide structure and support. Cartilage is composed of chondrocytes within a firm matrix, and there are three types: hyaline, elastic, and fibrocartilage. Bone tissue contains osteoprogenitor cells, osteoblasts, osteocytes, and osteoclasts embedded within an organic and inorganic matrix. Compact bone contains concentric osteons and interstitial lamellae that maximize strength. Bone develops through intramembranous or endochondral ossification involving cartilage models and growth plates.

It consist of detail content about different types of bone cells, two different type of bone formation and structure of long bone. easy to understand for students. language is simple.
The skeletal system provides structure and protection for the body. It is made of bones connected by ligaments at joints, and bone marrow inside bones produces blood cells. The skeleton changes over one's lifetime from a flexible newborn skeleton with over 300 bones to the 206 bone adult skeleton. Bones are constantly being built and repaired by osteoblasts and osteoclasts throughout life.
The musculoskeletal system is made up of bones, cartilage, ligaments, tendons and muscles, which form a framework for the body. Tendons, ligaments and fibrous tissue bind the structures together to create stability, with ligaments connecting bone to bone, and tendons connecting muscle to bone.

1. The skeletal system consists of bone and cartilage and performs several important physiological functions. It includes the bones of the axial skeleton such as the skull, vertebrae, ribs, and the bones of the appendicular skeleton like the shoulders, arms, hips, and legs.
2. Bones are made of both living and non-living materials. The living parts include bone cells while the non-living parts include the bone matrix made of collagen and hydroxyapatite. Bones can be classified based on their microscopic structure and location in the body.
3. The skeletal system allows for movement through joints which can be fibrous, cartilaginous, or synovial. The main types of synovial
Cartilage and bone are connective tissues that provide structure and support. There are three types of cartilage - hyaline, fibro, and elastic - each with different compositions and locations in the body. Bones contain bone tissue as well as other tissues. Bones function to provide structure, protect organs, allow movement via muscle attachment, produce blood cells, and store minerals and energy. There are four classes of bones - long, short, flat, and irregular - with different shapes and locations. Bones grow and remodel through both interstitial and appositional growth.
The document summarizes basic human anatomical structures. It describes the layers of skin, types of fascia, and three main types of muscle - skeletal, smooth, and cardiac. It also outlines the functions of bone, classifications of bones regionally and by shape, and differences between compact and cancellous bone. Key bones and muscle groups are defined along with muscle actions and nerve supply.
The document summarizes key aspects of the locomotor system and skeleton. It describes the skeleton's main functions of providing shape, support, protection and movement. The skeleton is divided into the axial skeleton of the skull, vertebral column, ribs and sternum, and the appendicular skeleton of the limbs. Typical long bones have a shaft, ends, and growth plate. Bones are classified based on shape and composition. Key markings and structures of bones are also defined.
The skeletal system performs several critical functions:
1. It supports the body and facilitates movement by providing attachment points for muscles and acting as levers.
2. Bones protect internal organs such as the lungs, heart, and brain.
3. The skeletal system stores and releases minerals and produces blood cells. Bones store minerals like calcium and release them when needed, and bone marrow produces red blood cells, white blood cells, and platelets.
The skeletal system includes bones, joints, cartilages, and ligaments. It is subdivided into the axial skeleton which forms the longitudinal axis of the body, and the appendicular skeleton which includes the bones of the limbs and girdles. Bones have several functions including support, protection, movement, storage, and blood cell formation. There are four classifications of bones based on shape: long bones, short bones, flat bones, and irregular bones. The structure of long bones includes a diaphysis, epiphyses, articular cartilage, medullary cavity, and microscopic features like osteons, lacunae, and canaliculi.
The skeletal system is composed of bones and associated tissues that provide structure, protection, movement, and mineral storage. Bones are living tissues composed of cells, collagen fibers, and minerals. There are four types of bones - long, short, flat, and irregular - with different structures adapted to their functions. Bones develop through intramembranous or endochondral ossification and are remodeled throughout life by bone cells.

The document summarizes the skeletal and muscular systems. It discusses that the typical human skeleton consists of 206 bones divided into the axial and appendicular skeleton. The axial skeleton includes the skull, vertebral column, ribs, and sternum, while the appendicular includes the shoulder and pelvic girdles and upper and lower limbs. It also describes the different types of joints like fibrous, cartilaginous, and synovial joints and provides examples. Finally, it provides a brief overview of muscle tissues and physiology.
The document discusses the classification and structure of bones. Bones are classified based on their shape as long, short, flat, irregular, or sesamoid. Long bones have a shaft and expanded ends, and contain mostly compact bone. Short bones are cube-shaped with mostly spongy bone. Flat bones are thin with layers of compact bone around spongy bone. Irregular bones have irregular shapes. Microscopically, bones contain compact and spongy bone. Compact bone is dense with concentric circles while spongy bone has trabeculae and spaces. Bones provide structure, protection, movement, mineral storage, and blood cell production.
The skeletal system provides structure and protection to the body. There are two types of skeletons - exoskeletons found in arthropods, and endoskeletons found in vertebrates like humans. The human skeleton consists of 206 bones and is made up of bone tissue, cartilage, and ligaments. Bones provide structure, protect organs, allow movement, and store minerals.
The document discusses the anatomy and physiology of bones in the human body. It begins by defining anatomy, physiology, and osteology. It then describes the different types of bones - long, short, flat, irregular, and sesamoid. It details the structure of bones, including compact and spongy bone. It also discusses bone development through intramembranous and endochondral ossification. In summary, the document provides an overview of the types of bones in the human body and how they develop and are structured.
Fibrous joints are held together by fibrous connective tissue with no joint cavity. Synovial joints contain synovial fluid and are freely movable, characterized by hyaline cartilage covering the bone ends, a synovial membrane surrounding the joint cavity, and a fibrous capsule made of ligaments. There are six types of movement in synovial joints: gliding, hinge, pivot, condyloid, saddle, and ball and socket. The four types of bones are long, short, flat, and irregular bones. Long bones have a shaft and two expanded ends, while short bones can be any shape and flat bones are shallow plates that form boundaries.
The document describes the classification and structure of bones. It discusses the five categories of bone classification based on shape - long, short, flat, irregular, and sesamoid. It then describes the gross anatomy and microscopic structure of long bones, including their diaphysis, epiphyses, epiphyseal plate, periosteum, endosteum, and medullary cavity. Finally, it discusses the histology and microscopic anatomy of compact and spongy bone, including osteons, lacunae, lamellae, central canals, Volkmann canals, trabeculae, and the cells and tissues involved in bone formation and structure.
The skeletal system comprises bones and cartilages that support the body, allow for movement, protect internal organs, and produce blood cells. There are two main types of bones - long bones in the limbs and flat/irregular bones in the skull, vertebrae, and pelvis. Bones form through either intramembranous or endochondral ossification and are constantly remodeled throughout life. The axial skeleton includes the skull, vertebral column, and thoracic cage, providing structure and protection to the head, neck and trunk.
The skeletal system has three main functions: providing structure and shape to the body, protecting vital organs, and allowing for bodily movement. It is made up of 206 bones that form the axial skeleton (skull, vertebrae, ribs, sternum) and appendicular skeleton (limbs and girdles). Bones are living tissues composed of compact bone, spongy bone, bone marrow, and various bone cells. They provide structure through their interaction with muscles, tendons, and ligaments at joints like the ball-and-socket hip. The skeletal system also plays roles in blood cell production and mineral storage.

2. FOUR TYPES OF BONES:
Short bones: carpals and tarsals (bones in your fingers and toes)
Flat bones: Calvarium (skull bone), sternum, or scapula
Long bones: femur, tibia and fibula (all leg bones) or humerus, radius and ulna
(arm bones)
Irregular bones: bones that can't fit into the above categories: vertebrae
(spine), hyoid, maxilla and mandible (jaw), and the bones of your sinuses:
Six Major structures of a
typical long bone:
ethmoid, zygomatic, and sphenoid (1)
Diaphysis: main or midsection/ shaft of a long bone. Made up of cortical bone
and usually contains bone marrow and adipose tissue.
Epiphyses: End of a long bone that is originally separated from the main bone.
(1)
Articular Cartilage: smooth, white tissue that covers the ends of bones in joints.
(1)
Periosteum: a specialized connective tissue covering all bones and having
bone-forming potentialities. (1)
Medullary (marrow) Cavity: space in a bone where a soft, flexible substance
called marrow is stored. (1)
5. HaversianCanal; nutrients and oxygen move through canaliculi to the Lacunae
and their bone cells--- a short distance of about 0.1 mm or less.
Volkmann’s canal and communicating canals that contain nerves and vessels
that carry blood and lymph from the exterior surface of the bone to the
Osteons.
Osteons- Compact bones that contain many cylinder-shaped structural units.
Homeostatic Functions of
Bones
1. Support – bones act as the framework for our body, creating the shape of our
skeleton
2. Protection –our bones help protect our vital organs, like the rib cage protects
our lungs and heart
3. Movement – Our muscles are attached to our bones which allow us to move
at the joints
4. Mineral Storage – Bones store many minerals, such as calcium and
phosphorus. Homeostasis blood calcium concentration is vital to living, it has
to be equal levels in the bone and the blood (1.)
5. Hematopoiesis (blood cell formation)– a vital process carried out by red
bone marrow(1.)
6. Ossification
Intramembranous ossification takes place in a connective tissue membrane. It
usually involves the flat bones while endochondral ossification usually deals with long
bones.
Intramembranous ossification deals with the fetus. Ground substance and the
collagenous fiber make the organic bone matrix. Calcification of the matrix forms
and continues until the trabeculae appear and form spongy bone. (1)
Endochondral ossification is from cartilage models with bone formation
spreading from the center to the ends. The bone continues to grow through primary
ossification center and secondary ossification center. An epiphyseal plate remains
Repair of Bone
Fractures
between the epiphysis and diaphysis. (1)
A bone fracture tears and destroys blood vessels that carry nutrients to osteocytes,
which is what initiates the repair sequence. The fracture itself is the first step in the
bone repair process. The next step is the formation of a fracture hematoma. Then it is
the formation of internal and external callus, which bind the broken fragment
together which stabilizes the wound and allows the healing process to procede. And
after that the bone remodeling is complete. (1)
7. CARTILAGE
Hyaline Cartilage - provides firm support with some pliability. It covers
the ends of the long bones as articular cartilage , providing springy pads
that absorb compression at joints . Has resilient cushioning properties ;
resists compressive stress. Supports the tips of the nose , connects the ribs
to the sternum , and supports most of the respiratory system passages. The
skeletal hyaline comes during childhood as the epiphyseal plates , provide
for continued growth in length. Covers the ends of long bones in joint
cavities ; forms costal cartilages of ribs , nose , trachea , and larynx. (1)
Elastic Cartilage - Found where strength and exceptional stretch ability are
needed. Elastic cartilage forms the skeletons of the external ear and the
epiglottis. Maintain the shape of a structure while allowing great flexibility.
Similar to hyaline but more elastic fibers in matrix. (1)
Fibrocartilage- Compressible and resists tension well , found where strong
support and the ability to with strand heavy pressure are required. EX: the
spongy cartilage of the knee , Intervertebral discs Strength with the ability
to absorb compressive shock.
Less firm than the hyaline; thick collagen fibers predominate. (1)
8. Growth of Cartilage
Interstitial Growth: The cartilage cells within the substance of the tissue
mass divide and begin to secrete additional matrix. Internal division of
chondrocytes is possible because of the soft, pliable nature of cartilage
tissue. This type of growth is mostly seen during childhood and early
adolescence, when the majority of the cartilage is still soft and capable of
expansion from within (1)
Appositional Growth: This occurs when chondrocytes in the deep layer of
the perichondrium begin to divide and secrete additional matrix. The new
matrix is then deposited on the surface of the cartilage, causing it to
increase in size. This type of growth is unusual in early childhood but, once
it starts it continues beyond adolescence and throughout an individual’s
life. (1)
Classification of joints
Joints are classified into 3 major categories using a structural or a functional
scheme. If a structural classification is employed, joints are named
according to the type of connective tissue that joins the bones together,
(fibrous and cartilaginous) or by the presence of a fluid-filled joint capsule.
(synovial joints) (1)
If a functional classification scheme is used, joints are divided into three
classes according to the degree of movement they permit. (synarthroses,
amphiarthroses, and diarthroses) (Immovable, slightly movable and freely
moveable) (1)
9. Fibrous joints are synarthroses. The articulating surfaces of these joints fit
closely together.
The three types of fibrous joints are:
Syndesmoses- Joints on which fibrous bands connect two bones
Sutures- Found only in the skull, teeth like projections jut out from
adjacent bones and interlock with each other with only a thin layer of
fibrous tissue between them. (1)
Gomphoses: unique joints that occur between the root of a tooth and the
alveolar process of the mandible and maxilla. (1)
Cartilaginous Joints are amphiarthroses: The bones that articulate to form a
cartilaginous joint are joined together by either hyaline cartilage or
fibrocartilage. There are two types of these
Sychondroses: Joints that are characterized by the presence hyaline cartilage
between articulating bones
Symphyses: a joint in which a pad or disk of fibrocartilage connects two
bones (1)
Synovial joints
They are the body’s most moveable, numerous and the most anatomically
complex joints.
Seven types of structures for synovial joins
10. joint capsules, synovial membrane, articular cartilage, joint cavity, menisci
(articular disks), ligaments and bursea(1)
Synovial joints are divided into three main groups: Uniaxial, biaxial, and
multiaxial
Uniaxial joints: Synovial Joints that permit movement around only one
axis and in only one plane. EX: Hinge Joints and Pivot Joints
Biaxial joints: Diaphroses that permit movement around two perpendicular
axes in two perpendicular planes EX: Saddle Joints and Condyloid Joints
Multiaxial Joints: Joints that permit movement around three or more axes
and in three or more planes EX: Ball and Socket joints and Gliding joints
(1)
Questions
The 2 functions that have gone awry that cause the need for a bone
marrow transplant and osteoporosis are low bone mineral density due to
not enough calcification. The normal process should be the calcification of
highly specialized crystals of calcium and phosphate. A bone marrow
transplant is performed if someone has damaged bone marrow, normally
red blood marrow produces red blood cells and yellow bone marrow is
saturated in fat not involved in blood cell production but can change to red
bone marrow
if needed. (1)
11. A fracture in the epiphyseal plate can cause problems in kids because
their bones have not finished growing, the epiphyseal plate is there as a
barrier between the shaft and end of the bone and if it gets fractured it can
cause problems in the ossification process.
As you get older your bones start to weaken and you start to have
bone loss. With this bone loss comes changes in your skeletal frame, you
get shorter and can have a humped back. You also have remodeling of in
compact bone which involves new haverian systems. (1)
