Your skull provides structure to your head and face while also protecting your brain.

Bones of the Skull

The mandible , located inferiorly in the facial skeleton, is the largest and strongest bone of the face. It forms the lower jaw and acts as a receptacle for the lower teeth. It also articulates on either side with the temporal bone, forming the temporomandibular joint. Fig 1 — Anterior and lateral views of the mandible within the facial skeleton. The mandible consists of a horizontal body anteriorly and two vertical rami posteriorly.

The body and the rami meet on each side at the angle of the mandible. The symphysis encloses a triangular eminence — the mental protuberance, which forms the shape of the chin. Each ramus contains the following bony landmarks:. The internal surface of the ramus is also marked by the mandibular foramen , which acts as a passageway for neurovascular structures. A foramen refers to any opening through which neurovascular structures can travel. The mandible is marked by two foramina. It serves as a conduit for the inferior alveolar nerve and inferior alveolar artery.

They travel through the mandibular foramen, into the mandibular canal, and exit at the mental foramen. It allows the inferior alveolar nerve and artery to exit the mandibular canal. The mandible serves as the attachment point for the various muscles, including the strong muscles of mastication. The temporalis muscle attaches to the coronoid process , and the masseter attaches to the rami.

The lateral pterygoid inserts into the neck of the mandible, and the medial pterygoid inserts into the ramus near the angle of the mandible. The mandible articulates with the temporal bone to form the temporomandibular joint which is discussed in more detail here.

A mandibular fracture rarely occurs in isolation. Much like fractures of the pelvic brim, a fracture on one side is frequently associated with a fracture on the contralateral side. Therefore, if one fracture is observed, another should be searched for. For example, a fractured neck of the mandible is often observed in conjunction with a fracture of the contralateral mandibular body.

Fig 4 — Multiple mandibular fractures marked by arrows. This illustrates that fractures of the mandible rarely occur in isolation. The symphysis encloses a triangular eminence - the mental protuberance, which forms the shape of the chin.

By TeachMeSeries Ltd Anatomical Structure The mandible consists of a horizontal body anteriorly and two vertical rami posteriorly.

Body The body of the mandible is curved, and shaped much like a horseshoe. It has two borders: Alveolar border superior — contains 16 sockets to hold the lower teeth. Neck — supports the head of the ramus, and site of attachment of the lateral pterygoid muscle.

Coronoid process — site of attachment of the temporalis muscle The internal surface of the ramus is also marked by the mandibular foramen , which acts as a passageway for neurovascular structures. Muscular Attachments The mandible serves as the attachment point for the various muscles, including the strong muscles of mastication. Mandibular body: External lateral surface — mentalis, buccinator, platysma, depressor labii inferioris, depressor anguli oris.

Internal medial surface — genioglossus, geniohyoid, mylohyoid and digastric. Articulations The mandible articulates with the temporal bone to form the temporomandibular joint which is discussed in more detail here.

Clinical Relevance: Fractures of the Mandible A mandibular fracture rarely occurs in isolation. The characteristics of mandibular fractures are as follows: Fractures of the coronoid process are uncommon and usually singular. Fractures of the neck of the mandible are often transverse and usually accompanied with dislocation of the temporomandibular joint.

Fractures of the angle of the mandible are usually oblique and may involve the alveolus of the 3rd molar.

Fractures of the body of the mandible frequently pass through the canine tooth. Found an error? Is our article missing some key information? Make the changes yourself here! Don't ask me again. This website uses cookies.

Bones are an important part of the musculoskeletal system. This article, the first in a two-part series on the skeletal system, reviews the anatomy and physiology of bone. The skeletal system is formed of bones and cartilage, which are connected by ligaments to form a framework for the remainder of the body tissues. This article, the first in a two-part series on the structure and function of the skeletal system, reviews the anatomy and physiology of bone. Understanding the structure and purpose of the bone allows nurses to understand common pathophysiology and consider the most-appropriate steps to improve musculoskeletal health.
