The articular disk of the temporomandibular joint is a thin, oval plate made of non-vascular fibrous connective tissue located between the mandible's condyloid process and the cranium's mandibular fossa. Its upper surface is concavo-convex from before backward, to accommodate itself to the form of the mandibular fossa and the articular tubercle ...
Rarely, the mylohyoid muscle may originate partially from other surfaces of the mandible. [2] The posterior (back) part of this line, near the alveolar margin , gives attachment to a small part of the superior pharyngeal constrictor muscle , and to the pterygomandibular raphe .
Translation Translation occurs in the upper TMJ compartment and provides most of the mandible's ability to open. Articular disc and condyle complex slide inferiorly on the articular eminences, allowing maximum depression of the mandible. [7] Maximal Mandibular Opening (T). Condylar heads are said to be at a maximum anterior-inferior position.
The facial artery typically crosses the inferior border of the mandible just anterior to the masseter muscle's insertion. In most instances, this crossing occurs at or in close proximity to the antegonial notch. This anatomical association has clinical relevance in various surgical procedures involving the face and mandible.

The mandibular incisive canal (indicated here by coral green arrows) continuing anteriorly (to the right) from the mandibular canal (purple arrows) after the mental foramen (light green circle). The mental foramen is one of two foramina (openings) located on the anterior surface of the mandible. It is part of the mandibular canal.
The four classical muscles of mastication elevate the mandible (closing the jaw) and move it forward/backward and laterally, facilitating biting and chewing. Other muscles are responsible for opening the jaw, namely the geniohyoid, mylohyoid, and digastric muscles (the lateral pterygoid may play a role).
