The muscles of mastication develop from the first pharyngeal arch. Thus, they are innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.@Vimal Modi

Muscles of mastication are derived from 1st pharyngeal arch , so mandibular nerve is the nerve of 1st arch hence should be supplied by it

Because they develop from a common arch?

1st pharyngeal OR mandibular arch.

Unlike most of the other facial muscles, which are innervated by the facial nerve (or CN VII), the muscles of mastication are innervated by the trigeminal nerve (or CN V). More specifically, they are innervated by the mandibular branch, or V3. The Mandibular nerve is both sensory and motor
