This document discusses the temporomandibular joint (TMJ), including that it is a synovial joint between the temporal bone above and the mandible below, with a fibrous articular disc that separates it into two compartments. The TMJ has capsular ligaments, a synovial membrane, and accessory ligaments like the sphenomandibular and stylomandibular ligaments. It lists muscles that control depression, elevation, protrusion, retraction, and side to side movements of the mandible. The document also lists TMJ disorders like dislocation, ankylosis, osteoarthritis, and lockjaw.

pterygoid.
 Elevation – masseter.
 Protrusion – lateral and
medial pterygoids.
 Retraction – posterior
horizontal fibres of the
temporalis.
 Side to side movements
– lateral pterygoid and
medial pterygoid and
vice versa.
