External oblique line of the mandible (shown in red) A vertical incision is performed on the inferior and lateral sides of the soft tissue in the mouth at a distance from the adjacent gums . [ 17 ] The cut is performed from the mandibular ramus to the mandibular body along the external oblique line, down to the mandibular first molar region ...
The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
The adult mandible is the skull's largest and strongest bone. [2] In old age, the bone can become greatly reduced in volume where there is a loss of teeth, and consequent resorption of the alveolar process and interalveolar septa. Consequently, the chief part of the bone is below the oblique line.
Since the mandible can go through a vast number of different movement paths, Posselt decided to start by studying the "border movements", a term he uses to denote the mandible's capacity for movement. Then he compared these with the habitual movements of the mandible. From the investigation, he concluded that:
Because the attachment of the mylohyoid muscle (the mylohoid line of the mandible) becomes more superior towards the posterior of the mandible, posterior infected teeth are more likely to drain into the submandibular space, and infected anterior teeth are more likely to drain into the sublingual space, since the apices of the teeth are more ...
In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth).

In anatomy, the zygomatic arch (colloquially known as the 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 ...
This site is at the apex of the maximum curvature of the mandible, where the ascending ramus becomes the body of the mandible. The mandibular angle has been named as a forensic tool for gender determination, but some studies have called into question whether there is any significant sex difference in humans in the angle.
