What is Facial Nerve Pathway Overview about?
The cranial nerves and cervical plexus innervate structures in the head and neck. Cranial nerve V, the trigeminal nerve, has three branches that provide sensory innervation to parts of the face and mouth. Cranial nerve VII, the facial nerve, exits the skull and divides to innervate the muscles of facial expression. Injuries to specific cranial nerves can cause loss of certain functions like tearing or facial muscle movement.
