Temporomandibular ligament

Temporomandibular Ligament

The Temporomandibular Ligament (also known as the lateral ligament) is a ligament in the human body that connects the mandible (lower jaw) to the temporal bone of the skull. It is a key component of the Temporomandibular joint, which allows for movement of the jaw.

Etymology

The term "Temporomandibular" is derived from the Latin words "tempus" meaning "time" and "mandibula" meaning "jaw". The term "ligament" comes from the Latin "ligare" meaning "to bind".

Anatomy

The Temporomandibular Ligament is a thick, strong band of fibrous tissue. It extends from the zygomatic process of the temporal bone and the articular tubercle, downwards and backwards to the neck of the mandible. It is on the lateral side of the Temporomandibular joint and serves to restrict the movements of the joint.

Function

The primary function of the Temporomandibular Ligament is to prevent the excessive retraction or displacement of the mandible, also known as posterior dislocation. It also aids in the smooth operation of the Temporomandibular joint, allowing for the opening and closing of the mouth, as well as the lateral or side-to-side movement of the lower jaw.
