Facial nerve and facial muscles

The video tutorial explains the innervation of facial expression muscles by the facial nerve (cranial nerve VII). It details the nerve's origin in the pons, its pathway through the internal acoustic meatus, and its exit via the stylomastoid foramen. The tutorial describes the five branches of the facial nerve—temporal, zygomatic, buccal, mandibular, and cervical—and uses the mnemonic 'To Zanzibar By Motor Car' for memorization. It highlights the nerve's role in eye closure, taste, and glandular functions, excluding the parotid gland, which is innervated by cranial nerve IX. The video concludes with acknowledgments for visual aids.
