What Major difference in muscular movement produced by the masseter and the temporalis during masification?

The major difference between the masseter and temporalis muscles during mastication lies in their function and movement direction. The masseter primarily facilitates vertical movement by elevating the mandible to close the jaw, enabling powerful chewing. In contrast, the temporalis muscle contributes to both elevation and retraction of the mandible, allowing for a more complex movement pattern that aids in grinding food. Together, these muscles work synergistically to ensure effective mastication.
