What characterizes a condyloid joint?

A condyloid joint, also known as an ellipsoidal joint, is characterized by a shallow depression at the end of one bone that receives a rounded end from another bone. This structure allows for movement in two planes: flexion and extension, as well as abduction and adduction. The rounded end of the bone fits into the concave surface, creating a stable yet flexible joint.

In contrast, the other options describe different types of joint characteristics or movements that do not apply to condyloid joints. For example, limiting movement to one plane or allowing rotation around an axis pertains more closely to hinge and pivot joints respectively, while permitting sliding motion is associated with plane synovial joints. By understanding these unique properties, one can better grasp the functional dynamics of condyloid joints within the body's skeletal framework.
