In human anatomy, the mandible's coronoid process (from Greek korōnē 'hooked') is a thin, triangular eminence, which is flattened from side to side and varies in shape and size. Its anterior border is convex and is continuous below with the anterior border of the ramus .
This is a very broad area of attachment. [2] It passes medial to the zygomatic arch . It forms a tendon which inserts onto the coronoid process of the mandible , with its insertion extending into the retromolar fossa posterior to the most distal mandibular molar. [ 3 ]
The condyloid process, the superior (upper) and posterior projection from the ramus, makes the temporomandibular joint with the temporal bone. The coronoid process, superior and anterior projection from the ramus. This provides attachment to the temporal muscle. Teeth sit in the upper part of the body of the mandible.

In anatomy, the zygomatic arch, or cheek bone, is a part of the skull formed by the zygomatic process of the temporal bone (a bone extending forward from the side of the skull, over the opening of the ear) and the temporal process of the zygomatic bone (the side of the cheekbone), the two being united by an oblique suture (the zygomaticotemporal suture); [1] the tendon of the temporal muscle ...
The coronoid head of the masseter's tendon and muscle fibers run posterolaterally from the coronoid process of the mandible towards the posterior third of the zygomatic arch. Its function is believed to be the retraction of the mandible and the stabilization of the mandibular coronoid process. [6] [7]
The articular capsule (capsular ligament) is a thin, loose envelope, attached above to the circumference of the mandibular fossa and the articular tubercle immediately in front; below, to the neck of the condyle of the mandible. Its loose attachment to the neck of the mandible allows for free movement.
Interior of the mandible, side view. The buccinator crest can be seen posteriorly to the third molar. The buccinator crest (Latin crista buccinatoria) is a bony crest of the human mandible, that passes from the base of the coronoid process to the area of the third molar. [1] The alveolar border of the buccinator muscle attaches upon it. [2]
