Question

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

Answer 1

The accurate terms for describing the classification of the temporomandibular joint are condyloid and multiaxial. Therefore, the correct options are 2 and 3.

Step-by-step explanation:

The temporomandibular joint (TMJ) is a unique joint that facilitates the complex movements of the jaw. Among the given terms:

1. Spheroid: This term is not typically used to describe the classification of joints. Spheroid generally refers to a three-dimensional geometric shape resembling a sphere.

2. Condyloid: This term is applicable to the temporomandibular joint. A condyloid joint is characterized by an oval-shaped condyle fitting into an elliptical socket, allowing for a variety of movements. The TMJ is indeed considered a condyloid joint.

3 Multiaxial: This term refers to joints that allow movement in multiple axes. The temporomandibular joint is indeed multiaxial, allowing for diverse jaw movements.

4. Saddle: This term is not typically used to describe the temporomandibular joint. A saddle joint is found in the thumb, for instance, allowing for a wide range of movements.

Therefore, the correct options are 2 and 3.
