Question

the radiocarpal joint is a ______ joint. condylar hinge glide saddle pivot

Explanation:

The radiocarpal joint, also known as the wrist joint, is a condylar joint. A condylar joint allows for movement in two planes - flexion - extension and abduction - adduction. Hinge joints allow movement in only one plane (like the elbow), glide joints allow bones to slide past one another (e.g., between carpal bones), saddle joints have a concave - convex relationship (like the thumb joint), and pivot joints allow rotational movement (like the joint between the atlas and axis in the neck).

Answer:

A. condylar
