- 1definition: gangliongroup of cell bodies outside of the CNS (notable exceptions include the Basal Ganglia)
- 2definition: nucleusgroup of neuronal cell bodies
- 3definition: tractgroup of axons within the CNS with the same origin and destination (e.g. cortico-spinal tract)
- 4definition: nervegroup of axons within the PNS with the same origin and destination
- 5definition: pathwayroute within the nervous system of interconnected axons (typically comprising of more than 1 tract)
- 6description: spinal nerves31 spinal nerves:
- 8 cervical
- 12 thoracic
- 5 lumbar
- 5 sacral
- 1 coccygeal
All leave through corresponding intervertebral foramen however the spinal cord ends at vertebral level L1/L2.
Thereafter, the spinal cord becomes the cauda equina (horse's tail) - 7classification of efferent nervesgeneral somatic efferent (GSE)

special visceral efferent (SVE) - 8definition: general somatic efferent (GSE) nervesfibres to skeletal muscle of somitic origin
- 9definition: general visceral efferent (GVE) nervesfibres to smooth & cardiac muscle and glands
- 10definition: special visceral efferent (SVE) nervesfibres to braciocephalic skeletal muscle

special visceral afferent (SVA) - 12definition: general sensory afferent (GSA) nervesreceive somatosensory signals
- 13definition: general visceral afferent (GVA) nervesreceive signals from visceral organs and blood vessels
- 14definition: special visceral afferent (SVA) nervesreceive signals from the gastrointestinal tract including the special senses of smell and taste
