Question

Which of the following are terms that describe the classification of the temporomandibular joints? 1) spheroid 2) multiaxial 3) saddle 4) condyloid

Answer 1

The classification of the temporomandibular joints includes condyloid, saddle, and ball-and-socket joints. The correct option is D.

Step-by-step explanation:

The classification of the temporomandibular joints includes several terms. One of them is condyloid. Condyloid joints are found at the base of the fingers (metacarpophalangeal joints) and at the wrist (radiocarpal joint). Another term is saddle.

At a saddle joint, the articulating bones fit together like a rider and a saddle. An example is the first carpometacarpal joint located at the base of the thumb.

Lastly, the term ball-and-socket also describes the classification of the temporomandibular joints. Ball-and-socket joints allow for the most movement, as they can move in multiple planes and rotate. The hip and shoulder joints are examples of ball-and-socket joints. The correct option is D.
