Final answer:
The muscles of mastication innervated by cranial nerve V3 (mandibular division) are the masseter and medial pterygoid muscles.
Step-by-step explanation:
Muscles of Mastication Innervated by Cranial Nerve V3 (Mandibular Division)
The muscles of mastication that are innervated by cranial nerve V3, also known as the mandibular division of the trigeminal nerve, include the following:
- Masseter: The masseter is the main muscle for chewing that elevates the mandible to close the mouth. It is the strongest muscle involved in mastication.
- Medial Pterygoid: The medial pterygoid muscle moves the mandible from side to side during chewing.
Example:
When you chew, you can feel the contraction of the masseter and medial pterygoid muscles in your jaw.
