Nerves of the Head

Overview

The nerves of the head provide sensory input, autonomic control and motor function. This section outlines the major pathways that supply the face, scalp and associated structures.

Key Structures

Topics include sympathetic and parasympathetic innervation, and the branches of the trigeminal nerve: ophthalmic, maxillary and mandibular.

Clinical Relevance and Learning Focus

Knowledge of head nerve pathways supports diagnosis of neuralgia, autonomic dysfunction and sensory loss. This anatomy underpins cranial nerve examination and interpretation of nerve lesions.
