Question

Which description applies to hinge joints?

Answer 1

Answer:

A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend.

Answer 2

In a hinge joint, the convex surface of one bone fits into a concave depression of another bone. A hinge joint enables movement only in one plane, or a back-and-forth movement. The elbow joint and the knee joint are hinge joints. Because the jaw moves in only one direction, the joint between the jaw and the skull is a hinge joint.
