== Nervous system ==
Neurons are the primary components of the [[nervous system]], along with the [[glial cells]] that give them structural and metabolic support.<ref name="Moore3">{{Cite book|title = Clinically Oriented Anatomy|last1 = Moore|first1 = Keith|last2 = Dalley|first2 = Arthur|publisher = LWW|year = 2005|isbn = 0-7817-3639-0|edition = 5th|pages = [https://archive.org/details/clinicallyorient00moor_1/page/47 47]|quote = A bundle of nerve fibers (axons) connecting neighboring or distant nuclei of the CNS is a tract.|url-access = registration|url = https://archive.org/details/clinicallyorient00moor_1/page/47}}</ref> The nervous system is made up of the [[central nervous system]], which includes the [[brain]] and [[spinal cord]], and the [[peripheral nervous system]], which includes the [[autonomic nervous system|autonomic]], [[Enteric nervous system|enteric]] and [[somatic nervous system]]s.<ref>{{Cite web |title=What are the parts of the nervous system? |date=October 2018 |url=https://www.nichd.nih.gov/health/topics/neuro/conditioninfo/parts |access-date=2022-07-08 |language=en}}</ref> In vertebrates, the majority of neurons belong to the [[central nervous system]], but some reside in peripheral [[ganglion|ganglia]], and many sensory neurons are situated in sensory organs such as the [[retina]] and [[cochlea]].

Axons may bundle into [[nerve fascicle]]s that make up the [[nerve]]s in the peripheral nervous system (like strands of wire that make up a cable). In the central nervous system bundles of axons are called [[nerve tract]]s.
