
Grey Matter

◦ Cell bodies of neurons
◦ Dendrites
White Matter


Axons
Grooves
◦ Dorsal median sulcus
◦ Ventral fissure

Horns
◦ Dorsal horns – sensory neurons
◦ Ventral horns – motor neurons

White matter is organized into three columns
◦ Anterior, Lateral, and Posterior

◦ Sensory Ascending Tracts conduct nerve impulses
to the brain
◦ Motor Descending Tracts transmit impulses down
the spinal cord
