Sort: Oldest first
Is a symmetrical, nearly parabolic bone, the middle portion of which is horizontal and called the body; and the posterior is vertical, the angular portions being termed Rami or branches. These have behind a parotidean edge, which forms- by uniting with the base the angle of the jaw. The branches terminate above by two processes, separated by the sigmoid notch or fossa; the anterior of which is called the coronoid; the posterior, the condyloid process or maxillary condyle, supported by a Cervix, Collum, or Neck. The chief parts observed on the the lower jaw are- 1. Externally, - Mental foramen, and the external oblique line. 2. Internally, - the internal or Myloid obligue lines, and the entrance of the dental canal. The lower jaw has, also, an alveolar edge, which contains alveoli for the reception of the teeth. The lower jaw-bone is developed by two points of ossification, which unite at the symphysis of the chin. It is articulated with the temporal bone and with the teeth.
