Nov 3, 2023 · The mandible consists of two main parts: a body and two rami. These parts feature various anatomical landmarks that participate in important functions of the mandible, for example housing the teeth and providing the passage for neurovascular structures. This article will discuss the anatomy of the mandible.

The body of the mandible is curved, and shaped much like a horseshoe. It has two borders: 1. Alveolar border (superior) – contains 16 sockets to hold the lower teeth. 2. Base (inferior) – site of attachment for the digastric muscle medially The body is marked in the midline by the mandibular symphysis. This is a small ridge of bone that represents ...
There are two mandibular rami, which project perpendicularly upwards from the angle of the mandible. Each ramus contains the following bony landmarks: 1. Head – situated posteriorly, and articulates with the temporal bone to form the temporomandibularjoint. 2. Neck– supports the head of the ramus, and site of attachment of the lateral pterygoid mus...
A foramen refers to any opening through which neurovascular structures can travel. The mandible is marked by two foramina. Themandibular foramenis located on the internal surface of the ramus of the mandible. It serves as a conduit for the inferior alveolar nerve and inferior alveolar artery. They travel through the mandibular foramen, into the man...

Jun 7, 2023 · The mandible, also known as the lower jaw, is a vital bone in the anatomy of the human body. It is the largest and strongest bone in the face, and it plays a key role in the functioning of the mouth and facial muscles.
Oct 30, 2023 · The temporomandibular joint (TMJ) is a hinge type synovial joint that connects the mandible to the rest of the skull. More specifically, it is an articulation between the mandibular fossa and articular tubercle of the temporal bone, and the condylar process of the mandible.
In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lower – and typically more mobile – component of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones.
The temporomandibular joint (TMJ), or jaw joint, is a synovial joint that allows the complex movements necessary for life. It is the joint between condylar head of the mandible and the mandibular fossa of the temporal bone.

Apr 1, 2023 · Introduction. The mandible is the largest bone in the human skull, forming the lower jawline and shaping the contour of the inferior third of the face (see Image. Mandible Anatomy). [1] Articulation with the skull base at the bilateral temporomandibular joints allows a range of movements facilitated by associated muscles, including dental ...
