![]() ![]() The third branch goes towards the lower lip. They are the buccal nerve and the lingual nerve. Two branches run on each side of the body of the mandible. The other one runs along the superior border of the mandible and divides into four branches. One nerve runs along the inferior border of the mandible. ![]() The movable bone in the skull contains two main nerves. The lateral pterygoid muscle attaches to the mandibular ramus through the angular process. The medial pterygoid muscle attaches to the mandibular fossa through the infratemporal fossa. The masseter muscle attaches to the mandible through the mandibular fossa. The lateral pterygoid muscle retracts the mandible. The medial pterygoid muscle pulls the mandible forward. The masseter muscle acts to protrude the mandible. These are the masseter, medial pterygoid, and lateral pterygoid muscles. Three muscles control the movement of the mandible. Let’s now have a look at the various relations the only movable bone in the skull. The insertion point of the masseter muscle is located near the middle of the zygomatic arch. The masseter muscle originates from the mandible and is inserted into the temporal bone. The masseter muscle is responsible for chewing food. The location of the masseter muscle determines the location of the mandible. The size and shape of the teeth are determined by the size and shape of the mandible. The size of the roots of the teeth is proportional to the size of the alveolar process. The size of the alveolus determines the size of the root of the tooth. The alveolar process determines the size of the teeth. The size of the teeth is related to the size of movable bone in the skull. The height, breadth, and depth of the glenoid fossae of the temporal bone are greater in males than in females. The height and breadth of the condylar neck are greater in males than in females. The height of the condylar head is greater in males than in females. The corpus of males is broader than that of females. The corpus of males has a wider width than in females. In females, the corpus has a longer length than in males. The height of the corpus is greater in males than in females. In males, the angle of the ramus is more acute than in females. The angle of the mandible in males is less obtuse than in females. In males, the angle of the mandible is more acute than in females. As the cartilage calcifies, it forms a bony mass that will become the mandible. Ossification begins at the endochondral growth plate of the mandibular condyle. The only movable bone in the skull, the mandible ossifies during embryonic development. Protrusion and retrusion are used synonymously to describe movements of the mandible from an occlusal position towards or away from the midline of the face. This movement is called protraction and retrusion, respectively. The only movable bone in the skull is the mandible. The mandible is the lower jaw of a vertebrate. The mandible can be moved up and down and laterally. ![]()
