The seventh cranial nerve (CNVII) is also named the facial nerve. It mainly provides motor innervation to the muscles of the face, and also a small amount of sensory information for the tongue. The facial nerve allows you to make different facial expressions.
All cranial nerves (all nerves for that matter) have a nucleus (cell body) and axon (that carries nerve impulses away from the nucleus to other structures). There are two nuclei of CNVII - the facial motor nucleus and the superior salivatory nucleus. The distribution of the facial nerve is somewhat complex.

Damage to the facial nerve can occur anywhere along its long path.
