Joint Classifications Part II

Question 1

What does synovial membrane do?

Answer 1

Secretes synovial fluid for lubrication and nutrient transport

Question 2

What are capsular ligaments?

Answer 2

Thickenings of the joint capsule that provide additional support (e.g., MCL and LCL in the knee).

Question 3

What are intracapsular ligaments?

Answer 3

Ligaments inside the joint capsule that restrict movement (e.g., ACL and PCL in the knee).

Question 4

What are menisci?

Answer 4

Fibrocartilage pads in some synovial joints that act as shock absorbers (e.g., in the knee).

Question 5

What determines the stability and mobility of a joint?

Answer 5

Bone shape, ligament structure, and body surface contact.

Question 6

Which type of joint sacrifices stability for mobility?

Answer 6

Synovial joints, especially ball & socket joints like the shoulder, elbow etc.

Question 7

What are the 3 movement axes in synovial joints?

Answer 7

Uniaxial (one axis), biaxial (two axes) & multiaxial (many axes).

Question 8

What type of movement occurs in a hinge joint?

Answer 8

Flexion and extension (e.g., elbow, knee).
