Question

There are four muscles of mastication.Select the exception.
A)Buccinator
B)Masseter
C)Temporalis
D)Lateral pterygoid
E)Medial pterygoid

Accepted Answer

The buccinator muscle is not a muscle of mastication. It is a cheek muscle that is involved in pulling the cheeks inward, which aids in chewing and in blowing air out of the mouth. The other options, including the masseter, temporalis, lateral pterygoid, and medial pterygoid, are all muscles of mastication that are involved in the movement of the jaw during chewing.
