Description
The Temporalis muscle is a large, fan-shaped muscle located on the side of the head, just above the ear. It extends from the temporal bone of the skull to the lower jawbone (mandible) and is responsible for moving the jawbone during chewing and biting.
The muscle is involved in several oral functions, including biting, chewing, and grinding food. It is also involved in other facial movements, such as clenching the jaw, as well as some nonverbal expressions, such as showing anger or frustration.
The importance of the Temporalis muscle lies in its crucial role in oral function, particularly in chewing and biting food. It also plays a significant role in the overall structure and function of the jaw, helping to maintain proper alignment and positioning.
Dysfunction of the Temporalis muscle can lead to various issues, including difficulty chewing, jaw pain, and headaches. It can also contribute to the development of Temporomandibular joint (TMJ) disorder, a condition characterized by pain and dysfunction in the jaw joint.
