Editing Temporomandibular joint (section)

==Anatomy and Structure==

===1. Articular Surfaces===
* '''Mandibular Condyle''': The superior-posterior part of the mandibular ramus.
* '''Mandibular Fossa''' (Glenoid Fossa): The depression in the temporal bone.
* '''Articular Eminence''': The raised bony projection anterior to the fossa that guides the condyle during translation.

===2. The Articular Disc (Meniscus)===
The TMJ is divided into upper and lower compartments by a biconcave '''articular disc''' made of dense [[fibrocartilage]] (unlike most synovial joints which use hyaline cartilage). 
* The disc is avascular and non-innervated in its central load-bearing zone.
* It is attached posteriorly to the '''retrodiscal tissue''' (bilaminar zone), which is highly vascular and innervated.

===3. Ligaments===
The joint is stabilized by several key ligaments:
* '''Temporomandibular (Lateral) ligament''': Prevents excessive posterior and lateral displacement.
* '''Sphenomandibular ligament''': An accessory ligament.
* '''Stylomandibular ligament''': Limits excessive protrusion of the mandible.
