The coronoid process is located anteriorly, and the condyloid process is located posteriorly. In between these two processes is a concave notch, known as the mandibular notch. Passing through this notch are the following structures: Masseteric nerve Masseteric artery Masseteric vein Learn more about the anatomy of the mandible in this tutorial.

The temporomandibular joint is commonly referred to as the TMJ and is a synovial joint formed between the condyles of the mandible and the articular fossa and articular tubercle of the temporal bones of the skull. The articular surfaces of the temporomandibular joint are covered with fibrocartilage, and the joint is divided into two parts by the presence of a fibrous articular disc: The inferior part of the TMJ allows depression and elevation.
