What is another name for the articular disc in the TMJ?

The articular disc in the temporomandibular joint (TMJ), also known as the meniscus, plays a crucial role in the function of the joint. This fibrocartilaginous structure helps to absorb shock, distribute stress, and enable smooth movement between the mandibular head and the temporal bone of the skull.

The term "meniscus" is widely used in anatomy to describe a crescent-shaped structure found in various joints, particularly in the knee, where it serves a similar purpose of cushioning and enhancing the movements of the joint. In the context of the TMJ, referring to the articular disc as a meniscus highlights its importance in joint mechanics and health.

This terminology is significant in dental and medical practice, as understanding the structures involved in the TMJ can aid in diagnosing disorders, planning treatments, and improving patient care. Knowing that the articular disc is synonymous with the term "meniscus" allows healthcare professionals to communicate more effectively about related conditions and treatments.
