Question

What structure is most likely involved in the painful movement?

A) Articular disc
B) Medial pterygoid
C) Lateral pterygoid
D) Temporalis
E) Buccinator

Answer 1

The articular disc of the temporomandibular joint (TMJ) is the most likely structure involved in painful movement. Dislocation or damage to the disc can lead to symptoms like difficulty chewing, headaches, and lock jaw.

Step-by-step explanation:

The structure most likely involved in painful movement is the Articular disc of the temporomandibular joint (TMJ) in the jaw. The TMJ is responsible for the opening, closing, and side-to-side movements of the lower jaw. Dislocation or damage to the articular disc can result in painful symptoms such as difficulty chewing, headaches, and lock jaw.
