Q

What is the cartilage in symphysis

A

White fibrocartilage

17
Q

How much movement does symphysis allow and now long does it last

A

Limited mobility
Permanent

18
Q

Examples of symphysis

A

Intervertebral disc
Symphysis pubis
Joints between bones of sternum

19
Q

What is synovial joint composed of & mobility

A

Freely mobile
1 Space between bones
2 articularsurfaces
3 fibrous capsule
4 synovial membrane
5 synovial fluid

20
Q

Describe the structure of synovial joint

A

The two articular surfaces are covered with hyaline cartilage
They are then connected / surrounded by a fibrous capsule whose inner surface is covered with synovial membrane which also covers the non articular part of the bone inside the joint and the synovial membrane secrets and absorbs the synovial fluid which : act as a lubricant , provides nutrient to the articular cartilage and structures inside the joint and it allows free movement ofthe joint

21
Q

What structures could also be inside the joint

A

1 cartilage
2 tendon
3 ligaments

22
Q

Types of cartilages inside joints with examples

A
  • discs at the temporo-mandibular joint
  • labrum at the shoulder joint
  • meniscus in the knee joint
23
Q

Example of tendons in joint

A

The long head of biceps in the shoulder joint

24
Q

Example of ligament in joint

A

Cruciate ligament in knee joint

25
Q

Name of unaxial joint

A

Plane - gliding joint

26
Q

Explain the non axial joint and example

A

The two articular surfaces are flat
The only allowed movement is sliding over each other
INTER carpal and INTER tarsal joints

27
Q

Types of uniaxial joints

A

Hinge joint
Pivot joint

28
Q

Axis of hinge joint

A

Transverse axis

29
Q

Allowed movement of hinge joint and location

A

Flexion and extension
Elbow joint

30
Q

The axis of pivot joint

A

Longitudinal

31
Q

Allowed movement of pivot joint and location

A

Rotation
Superior radio-ulnar joint

32
Q

Types of biaxial joints

A

Ellipsiod
Saddle

33
Q

What is ellipsoid joint

A

Oval convexity recived in elliptical concavity

34
Q

Movement of ellipsoid joint and location

A

Flexion , exstension , adduction ,abduction
Metacarpo-phalangeal joint
Wrist joit

35
Q

What is saddle joint

A

The articular surfaces are concavo-convex

36
Q

What allowed movement in saddle and location

A

Extension , flexion , adduction , abduction , opposition
Thumb carpo-metacarpal joint

37
Q

What is poly axial joint

A

A ball like rounded head shaped bone recieved in a cup sucket shaped concavity

38
Q

Allowed movement of ball and socket and location

A

Flexion , extension , adduction , abduction , rotation
Shoulder joint ad hip joint

39
Q

What determines the stability of a joint

A

1 the shape , size and arrangment of articulating bones
2 the positiong and strength of ligaments
3 the contraction and tone of surrounding muscle
