A ______ joint consists of one ovoid bone end that fits into the elliptical cavity of another bone.Multiple choice question.condylarhingeplanepivot

The correct answer to the multiple-choice question is "condylar."

Explanation:

A condylar joint, also known as an ellipsoidal joint, features one bone end that is shaped into an ovoid (egg-shaped) structure that fits into an elliptical cavity on another bone. This unique structure allows for a significant range of motion, including flexion, extension, abduction, and adduction, but it does not allow for rotation. An example of a condylar joint is the wrist joint where the radius meets the carpals, allowing for movement in multiple planes.

In contrast, the other options represent different types of joints:

1. Hinge Joint: Allows movement primarily in one direction, similar to a door hinge (e.g., elbow).
2. Plane Joint: Allows for gliding or sliding movements between flat surfaces (e.g., between carpals in the wrist).
3. Pivot Joint: Allows for rotational movement around a single axis (e.g., the joint between the first and second cervical vertebrae).

Thus, the best fit for the description of the joint that consists of an ovoid bone end fitting into an elliptical cavity is the condylar joint.
