Jaw, either of a pair of bones that form the framework of the mouth of vertebrate animals, usually containing teeth and including a movable lower jaw (mandible) and fixed upper jaw (maxilla). Jaws function by moving in opposition to each other and are used for …

2023年7月17日 · Anatomy. The cranial surface of TMJ consists of the squamous area of the temporal bone; it takes the name of glenoid fossa and welcomes the condyle of the jaw. The posterior area of the fossa is known as posterior articular ridge; sideways to the latter, we find a bone portion called postglenoid process.

A jaw that’s too small, too large, or crooked can cause problems with chewing, speaking, breathing, and even sleeping. The shape of your jaws also affects the way your face looks. This sheet helps you understand how the teeth and jaws work.

This chapter illustrates the normal CT anatomy of the jaw. The jaw is a pair of bones forming the framework of the mouth, including the movable lower jaw (mandible) and fixed upper jaw (maxilla).

2015年10月1日 · Radiologists should possess working knowledge of the embryological development and anatomy of the jaw and dentition in order to aid in the diagnosis of both simple and complex disorders that affect them. Here, we review the elaborate process of odontogenesis, as well as describe in detail the anatomy of a tooth and its surrounding structures.

This lateral view of the skull (Panel A) shows the normal position of the mandible in relation to the maxilla, the temporomandibular joint capsule, and the muscles associated with jaw...

Anatomy of the Jaw. The jaw, also known as the mandible, is a key component of the human skull and plays a crucial role in various functions, including chewing, speaking, and facial expression. It is the largest and strongest bone in the face, consisting of a horizontal body and two upright ramus extensions on each side.
