What is the Temporalis Muscle?
The temporalis muscle is a broad, fan-shaped muscle located on the side of your head, spanning from the temporal bone of your skull down to your jawbone (mandible). It plays a crucial role in the movement of your jaw, specifically in chewing and speaking. When you engage in actions like biting or chewing, the temporalis muscle contracts, helping to lift the jaw upwards and draw it back if it’s protruding forward.
