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 .
Behind the optic foramen the anterior clinoid process is directed backward and medialward and gives attachment to the cerebellar tentorium . Behind the tuberculum sellae is a deep depression, the sella turcica, containing the fossa hypophyseos, which lodges the pituitary gland, and presents on its anterior wall the middle clinoid processes.
At the front part of this surface is a small rounded eminence for the origin of one head of the flexor digitorum superficialis muscle; behind the eminence is a depression for part of the origin of the flexor digitorum profundus muscle; descending from the eminence is a ridge which gives origin to one head of the pronator teres 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 Coronoid process (from Greek korone, "like a crown") can refer to: . The coronoid process of the mandible, part of the ramus mandibulae of the mandible; The coronoid process of the ulna, a triangular eminence projecting forward from the upper and front part of the ulna
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 ...
Investigators have determined that a skull discovered in the wall of an Illinois home in 1978 was that of an Indiana teenager who died more than 150 years ago, authorities announced Thursday.
The coronoid process of the mandible is positioned lower in relation to the overall skull unlike in ruminants, and the temporomandibular joint is also lower than in Amphimeryx. [7] [12] Pseudamphimeryx is also known from a brain endocast, although the endocasts of it and Amphimeryx were not as closely described in detail.
