The temporalis muscle is one of the four muscles of mastication, which are primarily responsible for the movements of the jaw during chewing and speaking. The temporalis muscle is notable for its fan-shaped appearance and is a crucial component in the elevation and retraction of the mandible. Understanding the anatomy, function, and clinical significance of the temporalis muscle can provide valuable insights into its role in both normal mastication and potential disorders of the temporomandibular joint (TMJ).

The muscles of mastication are a group of four muscles that are primarily responsible for the movement of the jaw. These muscles are essential for chewing (mastication), speaking, and any other activity that involves the opening and closing of the mouth. The muscles of mastication are located in the parotid and infratemporal regions of the head, and they work in harmony to allow for complex movements of the jaw. This article gives an overview of each muscle of mastication, their function, insertion and origin, and blood and nerve supplies.

Molar Teeth, or molars for short, are located at the very back of your mouth and play the largest role in mastication, the act of chewing. They are responsible for crushing through food. In this article, we will provide a breakdown of your 12 molars – what they are, where they’re located, and what their purpose is. We’ll also provide information on how to care for them properly!
