Cranial Nerve V - Trigeminal Nerve [Part 1] | Origin, Structure, Pathway & Function

The video tutorial covers the trigeminal nerve, cranial nerve 5, detailing its sensory and motor components. It explains the division into V1, V2, and V3, with a focus on the mandibular nerve's dual function. The tutorial highlights the muscles of mastication and their innervation by the trigeminal nerve. It describes the motor pathway, contrasting it with sensory pathways, and explains the role of corticobulbar tracts. The video concludes with a preview of cranial nerve 7, the facial nerve.
