Musculus temporalis

The video tutorial provides a comprehensive overview of the temporalis muscle, covering its origin, anatomical structure, innervation, and functions. The temporalis is a fan-shaped muscle located on the lateral side of the skull, playing a crucial role in chewing. It originates from the temporal fossa and attaches to the coronoid process of the mandible. The muscle is innervated by branches of the mandibular nerve, part of the fifth cranial nerve. Functionally, the temporalis muscle is involved in jaw movements such as protrusion, retrusion, and adduction, making it the strongest chewing muscle. The tutorial also explains the muscle's role in lateral jaw movements.
