Question

UpStudy AI · Accepted Answer

The metacarpalphalangeal (MCP) joints of the fingers (Digits 2-5) are classified based on their structure and movement capabilities. These joints allow for flexion, extension, abduction, and adduction, which are characteristics of a specific type of joint.
Let's analyze the options provided:
1. **Condyloid**: This type of joint allows movement in two planes (flexion/extension and abduction/adduction).
2. **Gliding**: This joint allows for sliding movements and is typically found in the wrist and ankle.
3. **Ball and Socket**: This joint allows for rotational movement and is found in the shoulder and hip.
4. **Hinge**: This joint allows movement primarily in one plane (flexion and extension), like the elbow and knee.

Given the movement capabilities of the MCP joints, they do not fit the hinge classification.
The MCP joints of the fingers (Digits 2-5) are condyloid joints.
