Temporomandibular Joint 😲 | Biomechanics Part 2/2

The video tutorial explores the temporomandibular joint (TMJ) focusing on the muscles involved in mouth opening and closing. It details the phases of mouth opening, highlighting the roles of the lateral pterygoid muscles and the articular disc. The movement of the hyoid bone is also discussed, emphasizing its importance in allowing maximal mouth opening. The tutorial concludes with the mechanics of mouth closing, involving the temporalis, masseter, and medial pterygoid muscles, and the role of stored elastic energy in the articular disc.

What is the significance of the tension on the articular disc during mouth closing?

Identify the muscles involved in mandibular elevation during mouth closing.

Discuss the differences in muscle function between mouth opening and closing.
