Anatomy of the Temporomandibular Joint

The Temporomandibular Joint (TMJ) is a complex structure essential for jaw movement. It’s one of the most used joints in the human body. It plays a key role in daily activities like eating, speaking, and yawning.

Structure and Function

The TMJ is a synovial joint that links the mandible (lower jawbone) to the temporal bone of the skull. It consists of the articular eminence, the mandibular condyle, and the articular disc.

• The articular eminence is a bony ridge on the temporal bone.
• The mandibular condyle is the rounded end of the mandible.
• The articular disc is a fibrous cartilage structure that facilitates smooth movement.

How the TMJ Works

The TMJ enables the jaw to move in various directions. It allows for hinge movement for opening and closing, and gliding movement for sideways motions.

This complex movement is facilitated by the coordination between the TMJ’s bony components, the articular disc, and the surrounding muscles and ligaments.

Relationship to Surrounding Structures

The TMJ is closely related to surrounding facial structures. This includes the muscles of mastication (chewing), nerves, and blood vessels.

1. The masseter and temporalis muscles are key in controlling jaw movement.
2. The auriculotemporal nerve provides sensory innervation to the TMJ.
3. The joint is also surrounded by a capsule that is rich in blood supply.
