Mandibular bone anatomy. It forms the lower jaw and holds the lower teeth in place. It is the only movable bone of the skull discounting the ossicles of the middle ear. Four different muscles connect.

The anterior portion of the mandible called the body is horseshoe shaped and runs horizontally. The mandible is the single midline bone of the lower jaw. The mandible or lower jaw is the bone that forms the lower part of the skull and along with the maxilla upper jaw forms the mouth structure.

It consists of a curved horizontal portion the body and two perpendicular portions the rami which unite with the ends of the body nearly at right angles angle of the jaw. Its superior border is the alveolar process. The body of the mandible anchors the lower teeth and forms the chin.

Each ramus contains the following bony landmarks. Here the most common bony disturbances have been noted. Introduction to mandible bone anatomy.

The mandible is composed of the body and the ramus and is located inferior to the maxilla. Neck supports the head of the ramus and site of attachment of the lateral pterygoid muscle. The mandible lower jaw or jawbone is the largest strongest and lowest bone in the human face.

It is formed by intramembranous ossification. The body is a horizontally curved portion that creates the lower jawline. Intra and extracapsular condylar fractures are the most frequent mandibular fractures.

The mental protuberance at this junction forms the chin. The mandible l mandere to chew is the facial bone that forms the lower jaw and contains the lower teeth. It holds the lower teeth in place it assists in mastication and forms the lower jawline.

The mandible is the largest bone in the human skull. The mandible is composed of 2 hemimandibles joined at the midline by a vertical symphysis. It is the only mobile bone of the facial skeleton and since it houses the lower teeth its motion is essential for mastication.

The mandible is a u shaped bone.
