35
Q

Describe the knee joint

A

Three joints in one, surrounded by a single joint cavity

36
Q

What are the eight ligaments that support the knee joint

A 
Patellar
Fibular collateral 
Tibial collateral
Cruciate ligaments
Anterior cruciate ligament
Posterior cruciate ligament
Two popliteal ligaments
37
Q

Patellar ligament extends from?

A

Extends from patella to tibial Tuberosity

38
Q

Fibular collateral ligament function?

A

Reinforces lateral surface of joint

Prevents hyperadduction of leg at knee

39
Q

Tibial collateral ligament function?

A

Reinforces medial surface of the knee

Prevents hyperabduction of the leg at knee

40
Q

Cruciate ligament function

A

Limit anterior and posterior movement of femur on tibia

41
Q

Anterior cruciate ligament function

A

Prevents hyperextension

prevents tibia moving too far anteriorly on the femur

42
Q

Posterior cruciate ligament function

A

Prevent hyperflexion

And posterior displacement of tibia on the femur

43
Q

What movements are allowed at the knee joint

A

Flexion

Extension

And some rotation in flexed position

44
Q

Describe the temporomandibular joint (TMJ)

A

Has a loose Articular capsule that surrounds the joint

Promotes extensive range of motion

Head of mandible articulation with temporal bone

45
Q

What type of joint is represented by the glenohumoral joint

A

Synovial:

Ball and socket

46
Q

What are the rotator cuff muscles

A

(SITS)

Supraspinatus

Infraspinatus

Teres minor

Subscapularis

47
Q

What is their role in relation to the stability of the glenohumoral joint

A

Work as a group to hold the head of the humerus in the glenoid cavity

48
Q

The glenohumoral joint is the most stable/unstable joint in the body?

A

Unstable

49
Q

Describe the hip joint

A

Ball and socket joint

Good range of motion

50
Q

What are the possible movements at the hip joints

A 
Flexion
Extension
Abduction
Adduction
Rotation
Circumduction
51
Q

How do the glenohumoral and hip joints compare in terms of stability and mobility

A

Hip not as mobile as the shoulder

But hip is more stable

52
Q

Read diseases and abnormal conditions related to joints

A
