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.

Explanation:

To solve this, we analyze each joint type:

• Pivot joints (A) allow rotation around a single axis (e.g., neck). Fingers don't have this.
• Saddle joints (B) have a saddle - shaped surface (e.g., thumb joint). Fingers (except thumb) don't have saddle joints.
• Condyloid joints (C) allow movement in two planes (flexion/extension, abduction/adduction) and are found in finger joints (metacarpophalangeal and interphalangeal joints).
• Ball - and - socket joints (D) allow multi - directional movement (e.g., shoulder, hip) and are not in fingers.

Answer:

C. condyloid joints
