What are the long bones?

A

They function for leverage. Examples include:
(Lower limb) The femur, tibia, fibula, metatarsal and phalanges

Q

What is the composition of a synovial joint?

A

Skin with bursa sac above the joint capsule. Outermost layer is the fibrous membrane which has a fat deposit above the synovial membrane. This secretes synovial fluid into the articular cavity between the articular cartilage of two bones meeting.

Q

What are the synarthroses joints?

A

Immovable bone between fibrous tissue and includes:
-sutures in the skull
-intranasal betwene maxilla and frontal bone.
-synchondroses-hyaline cartilage joint between diaphysis and epiphysis of a single bone
-gomphoses which are the articulation of the teeth with the maxilla or mandible

16
Q

What are the amphiarthrosis joints?

A

The syndesmosis: joint which has the tibiafibulararticulation and the radialulnar articulation. There is an interosseus membrane of fibrous tissue arranged in oblique which joins them
-the symphyses- fibrocartilage joint with some hyaline, eg pubic symphysis and vertebral joints
-cartilage that joints the ribs

17
Q

What are the diarthrosis joints?

A

Synovial joint which has articular cartilage lining the bone articulation.
Hip and shoulder joint
Hinge joint
Pivot joint

18
Q

difference between primary and secondary cartilaginous joint

A

Primary cartilagenous joint is formed by hyaline cartilage, such as synchondrosis. Secondary cartilagenous joint is formed by fibrocartilage, such as symphysis.

19
Q

What is a primary cartilagenous joint?

A

Synchondroses (immovable) joints where bone and hyaline cartilage meet composed of hyaline cartilage. It is found between the ribs and costachondral cartilage, between the diaphysis and epiphysis the ossification centre of developing bone, manubrium and sternum.

20
Q

What is a secondary cartilagenous joint?

A

Secondary cartilagenous joints are where articulation of hyaline cartilage. It is the sympheses formed of fibrocartilage. It includes the pubic symphysis, intervertebral discs and manubriosternal joint.

21
Q

What is the plane joint?

A

Between the tarsal bones and carpal bones where articular surfaces are flat and slide over each other

22
Q

What is the saddle joint?

A

Between concave and convex regions like the trapezium carpal bone and 1st metacarpal bone in the thumb

23
Q

What are the types of muscle?

A

Circular, covergent, parallel fusiforom, parallel non-fusiform and pennate (sub-divided into uni-pennate, bi-pennate and multi-pennate),

24
Q

What is a fasicle?

A

A bundle of muscle fibres bound together y the endomysium.

25
Q

What is a fusiform muscle?

A

Muscle where the fibres are parallel in a spindle shape such as the biceps brachii. The non fusiform muscle is the sartorius which has a rectangular shape

26
Q

Circular muscle

A

Orbicularis oris

27
Q

Convergent muscle

A

Pectoralis muscle

28
Q

Unipennate muscle

A

Extensor digitorum

29
Q

Parallel non-fusiform

A

Sartorius

30
Q

Parallel fusiform

A

Biceps brachii

31
Q

Multipennate muscle

A

Deltoid
