What type of joint movement does the ankle joint exhibit?

The ankle joint primarily exhibits a hinge movement, which allows for dorsiflexion and plantarflexion. This type of joint movement is characterized by allowing movement in one plane, much like how a door opens and closes.

While there are different classifications of joints, the ankle joint is classified as a synovial joint that functions predominantly as a hinge. The term "sellar" refers to a saddle joint, which allows for a wider range of movement than a simple hinge joint. The ankle does not function as a ball and socket joint (which allows for rotational movement), nor is it a fibrous joint, which typically involves connective tissue that does not permit movement.

Understanding these classifications helps clarify the specific movement abilities of various joints in the human body, highlighting the unique structure and function of the ankle joint in particular.
