Question

the joints in the fingers are
a. pivot joints
b. saddle joints
c. condyloid joints
d. ball - and - socket joints
please select the best answer from the choices provided.
a
b
c
d

Explanation:

• Pivot joints allow rotation around a single axis (e.g., between the first and second cervical vertebrae).
• Saddle joints (e.g., carpometacarpal joint of the thumb) have a saddle - shaped surface for a wide range of movement but not the type in fingers.
• Condyloid joints (metacarpophalangeal joints in fingers) allow movement in two planes (flexion - extension and abduction - adduction).
• Ball - and - socket joints (e.g., hip and shoulder) allow multi - directional movement (flexion - extension, abduction - adduction, rotation etc.), which is not the case for finger joints.

Answer:

C. condyloid joints
