Question

Quizplus · Accepted Answer

All three muscles (temporalis, masseter, lateral pterygoid, and medial pterygoid) may be involved in temporomandibular joint (TMJ) syndrome. The temporalis and masseter muscles are responsible for biting down or chewing, while the lateral pterygoid muscle helps to open and close the jaw and move it from side to side. The medial pterygoid muscle also helps to close the jaw and move it from side to side. Dysfunction or injury to any of these muscles can contribute to TMJ syndrome.
