Associate Terms

Body - thick, bony part of the mandible that anchors the teeth
Ramus - the vertical part of the mandible that rises to articulate with the cranial base
Mental foramen - large (sometimes multiple) foramen located on the corpus face, near mid-corpus, below the premolar region. Transmits the mental vessels and nerve.
Mandibular condyle - the large, rounded articular prominence on the posterosuperior corner of the ramus. Articulates with the temporomandibular joint.
Oblique line - a weak eminence that passes from the root of the ramus to the area at the rear of the mental foramen.
Coronoid Process - thin, triangular process of the ramus. Anterior surface is thickened and convex, and its posterior edge is concave and thinner. both medial and lateral surfaces serve as insertions for the temporalis muscle.
Mhylohyoid line - croses the medial corpus surface obliquely, beginning near the alveolar margin at the last molar position and diminishing as it runs anteriorly an inferiorly.
Gonial angle - the rounded posterinferior corner of the mandible. Masseter muscle attaches along the angle.
Mandibular torus - a thickening of the alveolar margin just lingual to the cheek teeth.
Masseteric tuberocity - the raised, roughened area at the lateral edge of the gonial angle at which the masseter muscle attaches.
Mandibular symphysis - the midline surfaces of unfused right and left mandibular halves of an individual less that 1yr.
Mandibular foramen - enters the bone obliquely, centered in the medial surface of the ramus.
Mhylohyoid groove - crosses the medial ramus surface, running anteroinferiorly from the edge of the mandibular foramen. Houses the mylohyoid vessels and nerve.
Mental eminence - the triangular eminence, or bony chin, at the base of the corpus in the anterior symphyseal region. Separated from the alveolar region by a pronounced incurvation in modern humans.
