Bones & its types
By,M. Thiru murugan
Define Bones & write its types
Bones:
Bone are specialized forms of strong connective tissue that forms the skeleton of the body.
It is composed of calcium phosphate and calcium carbonate.
It also serves as a storage area for calcium
The smallest bone in the human body is called the stirrup or stapes bone, located deep inside the ear & The longest bone & strongest bone in the human is called the femur.
Classification or types of bones:
Bones are divided into 5 types.
Long Bone
Short Bone
Flat Bone
Irregular Bone
Sesamoid Bone
1. Long Bone:
A long bone is one that is cylindrical in shape, being longer than it is wide.
Shape of a bone, not its size.
Long bones are found in: Arms (humerus, ulna, radius) & fingers (metacarpals, phalanges) and also Legs (femur, tibia, fibula), and toes (metatarsals, phalanges).
Long bones function as levers; they move when muscles contract.
2. Short bones:
cube-like in shape, equal in length, width, and thickness.
Example: Carpals of the wrists & Tarsals of the ankles.
Short bones provide stability and support as well as some limited motion.
3. Flat Bones:
The term “flat bone” is somewhat of a misnomer because, although a flat bone is typically thin, it is also often curved.
Examples include the cranial bones, the scapulae, the sternum, and the ribs.
Flat bones serve as points of attachment for muscles and often protect internal organs.
4. Irregular Bones:
An irregular bone is one that does not have any easily characterized shape and therefore does not fit any other classification.
These bones tend to have more complex shapes, like the vertebrae, Many facial bones, particularly the ones containing sinuses.
5. Sesamoid Bones:
A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed.
These bones form in tendons where a great deal of pressure is generated in a joint.
The sesamoid bones protect tendons by helping them overcome compressive forces.
Sesamoid bones vary in number and placement from person to person but are typically found in tendons associated with the feet, hands, and knees.
The patellae (singular = patella) are the only sesamoid bones found in common with every person.

Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
1. Joints of the Human Body
• Joint Classification
• Synovial Joints
–Characteristics of synovial joint
–Types of synovial joints
Naming Joints:
–Pectoral Girdle
–Upper Limb
–Pelvic Girdle
–Lower Limb
2. • Joint is a point of connection between
two bones
• Strands of connective tissue, ligaments,
hold the bones together and ensure the
stability of joints
3. Joint Classification
• Joints are classified according to their
motion capabilities:
– Synarthroses
• Immovable
– Amphiarthroses
• Slightly movable
– Diarthroses
• Allow the greatest amount of motion
4. Joint Classification Cont’d
• Joints are further classified by the material
that joints them:
– Fibrous joint
• Allow no movement
• E.g. sutures of the scull
– Cartilaginous joints
• Allow limited movement
• E.g. intervertebral discs
– Synovial joints
• Allow large range of movements
• E.g. hip joint
5. Characteristics of Synovial
Joints
• Hyaline cartilage
– A protective layer of dense white connective tissue that
covers the ends of the articulating bones
• Joint cavity
• Synovial membrane
– Covers joint cavity, except over the surfaces of the articular
cartilages
– Secretes the lubrication fluid
• Synovial fluid
– Lubricates the joint
• Capsule
– May or may not have thickenings called intrinsic ligaments
• Extrinsic ligaments
– Support the joint and connect the articulating bones of the
joint
6. Types of Synovial Joints
• There are three basic types of synovial
joints:
– unilateral (rotation only about one axis)
– biaxial joints (movement about two
perpendicular axes)
– multiaxial joints (movement about all three
perpendicular axes)
7. Types of Synovial Joints Cont’d
• Synovial are further classified into:
1. Hinge Joint
2. Pivot Joint
3. Condyloid Joint
4. Saddle-shaped joint
5. Ball and Socket Joint
6. Plane Joint
8. 1. Hinge (Ginglymus) Joint
• Uniaxial
• Has one articulating
surface that is
convex, and another
that is concave
• E.g. humero-ulnar
elbow joint,
interphalangeal joint
10. Condyloid (Knuckle) Joint
• Biaxial (flexion-extension, abduction-
adduction)
• The joint surfaces are usually oval
• One joint surface is an ovular convex shape,
and the other is a reciprocally shaped
concave surface
• E.g. metacarpophalangeal joint
11. Saddle Joint
• Biaxial (flexion-extension, abduction-
adduction)
• The bones set together as in sitting on
a horse
• E.g. carpometacarpal joint of the thumb
12. Ball and Socket Joint
• Multiaxial (rotation in all planes)
• A rounded bone is fitted into a cup=like
receptacle
• E.g. shoulder and hip joints
13. Plane (Gliding) Joint
• Uniaxial (permits gliding movements)
• The bone surfaces involved are nearly flat
• E.g. intercarpal joints and acromioclavicular joint
of the vertebrae
15. Sternoclavicular Joint
• Connects the sternum to the clavicle
• the only joint connecting the pectoral girdle to
the axial skeleton
• true synovial joint strengthened by an
intracapsular disc and extrinsic ligaments
16. Acromioclavicular Joint
• unites the lateral end of the clavicle with
the acromion process of the scapula
• where shoulder separations often occur
in sports such as hockey, baseball, and
football
17. Glenohumeral Joint
• Connects the upper limb and the scapula
• A typical multiaxial joint
• has a wide range of movement at this joint
• compromise = relative lack of stability
19. Elbow Joint
• There are three joints at the elbow:
– humero-ulnar joint
• medial (with respect to anatomical position)
• between the trochlea of the humerus and the olecranon
process of the ulna
– humero-radial joint
• lateral
• between the capitulum of the humerus and the head of the
radius
– radio-ulnar joint
• between the radius and the ulna
22. Hip Joint
- Between the head of the
femur and the cup
(acetabulum) of the hip bone
(os coxae)
– Like shoulder joint, hip joint is:
• ball and socket joint
• multiaxial joint that allows flexion-
extension, abduction-adduction
and circumduction
24. Hip Joint Cont’d
• unlike shoulder joint, hip joint is very stable
• in fact it is the body’s most stable synovial
joint due to:
– deepened socked (via lip or fibrocartilaginous
labrum )
– an intrinsic and very strong extrinsic ligaments
• dislocation in sports is not common, but can
occur in car collisions
• dislocate the head posteriorly or drive it
through the posterior lip of the actetabulum
27. Knee Joint Cont’d
• however, the knee joint is relatively stable
due to additional structural supports from:
– menisci
• shock-absorbing fibrocartilaginous discs
– anterior and posterior cruciate ligaments
• in the centre of the joint
– lateral and medial collateral ligaments
• extending from the sides of the femur to the tibia and
fibula
– the musculature that surrounds it
28. Knee Joint Cont’d
• movements:
– primary action is flexion-extension (e.g.
squat or jump)
– when flexed, medial and lateral rotation
can also occur
29. Ankle Joint
• talocrural or ankle joint
• involves several bones:
– medial and lateral
malleoli of the tibia and
fibula
– head of the talus
– calcaneus (heel bone)
Medial
malleolus
Lateral
malleolus
Talus
Calcaneus
