Anatomical terms of neuroanatomy

A cranial nerve nucleus is a collection of

brain stem that is associated with one or more of the cranial nerves. Axons carrying information to and from the cranial nerves form a synapse first at these nuclei. Lesions occurring at these nuclei can lead to effects resembling those seen by the severing of nerve(s) they are associated with. All the nuclei except that of the trochlear nerve
(CN IV) supply nerves of the same side of the body.

Structure

Motor and sensory

In general, motor nuclei are closer to the front (

dorsal). This arrangement mirrors the arrangement of tracts in the spinal cord
.

Location

This list documents nuclei by the part of the brain they are found in:

Nuclei present in the Pons
Nuclei present in the medulla
