näonärvi
Näonärvi, known in English as the facial nerve (cranial nerve VII), is the seventh cranial nerve. It provides motor innervation to the muscles of facial expression and carries special sensory and autonomic fibers. The nerve has a dual embryologic and functional character: a motor root and a nervus intermedius carrying taste fibers and parasympathetic fibers. Its fibers originate in the brainstem (facial motor nucleus and nervus intermedius) and it travels internal to the skull before emerging at the stylomastoid foramen to supply facial muscles.
Anatomy and course are characterized by a complex intracranial and intratemporal path. After leaving the brainstem,
Clinical significance includes facial nerve palsy, which causes weakness of facial muscles, inability to close the
