masseter
The masseter is a thick, rectangular muscle located in the jaw area. It plays a crucial role in the process of chewing by elevating the lower jaw, allowing the teeth to grind food. This muscle is one of the strongest in the human body relative to its size and is essential for mastication.
The masseter is innervated by the trigeminal nerve, specifically its mandibular branch. It has two main parts: the superficial and deep layers, which work together to provide powerful jaw movements. Proper function of the masseter is important for overall oral health and digestion.
