Mandible

Body: symphysis menti, mental protuberance, mental foramen, mylohyoid line

Ramus: mandibular foramen, mylohyoid groove, mandibular canal, angle, coronoid process, condyloid process ymandibular notch

Mandible (from latin mandibula, jawbone) or inferior maxillary bone is, tohether with the maxilla, the largest and Sorong bone of the face. It forms the lower and holds thelower teeth in place

Symphysis menti: the external surface of the mandible is marked in the median line by faint ridge, indicating the symphysis menti or line of junction
Of the tow piece of whichthe bone is composed at an early period of life.
Thisridge divides below and encloses a triangular eminece, the mental protuberance, the base of which is depressed in the center but raised on eitherside form the mental tubercle.
It serves as the origin for the geniohyoid and the genioglossus

Mental protuberance :symphysis of the external surface of h mandible divides below and encloses atriangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle

Mental foramen: is one of two holes (foramina)located on the anterior surface of the mandible. It permits passage of the mental nerve and vessels. The mental foramen descends slightly in edentulous individuals

Mylohyoid line: extending upwardand backward on either side form the lower part of the symphysis of the mandible is the mylohyoid line, which is the origin of the mylohyoid muscle; the posterior part of this line, near the alveolarmargin, give attachment to a small part the constrictor pharyngis superior, and to the pterygomandibular raphe.

Ramus of the mandible: (perpendicular portion) is quadrilateral in shape, and hastwo surfaces, four bores, and two processes

The mandible foramen is an opening on the internal surface of the ramus(posterior and perpendiculary oriented part of the mandible) for divisions of the...
