Which of the Following is True of the Chewing Muscles

Question

Which of the following is true of the chewing muscles?
A) Must be attached to the mandible
B) Are smooth muscle
C) Are called the muscles of deglutition
D) Cannot tetanize

Accepted Answer

The chewing muscles are attached to the mandible and are responsible for moving the jaw during the process of chewing (mastication). Smooth muscle is not found in the chewing muscles, as they are skeletal muscles. The muscles of deglutition are separate muscles that are responsible for swallowing. The chewing muscles can tetanize, meaning they can sustain a prolonged contraction.
