Cross Section Anatomy of the Spinal Cord. Like the brain, the spinal cord is also made up of regions of white matter and gray matter. White matter regions are comprised of axons. It appears white due to the myelin sheath on the axons. Gray matter regions are comprised of cell bodies and dendrites. Gray matter is the location of most synapses.

Spinal Cord Anatomy Parts and Spinal Cord Functions

The spinal cord is part of the central nervous system and consists of a tightly packed column of nerve tissue that extends downwards from the brainstem through the central column of the spine. It is a relatively small bundle of tissue (weighing 35g and just about 1cm in diameter) but is crucial in facilitating our daily activities..

Spinal Cord Segments - Cross-sectional Anatomy. The spinal cord is made up of 31 segments. Each segment gives rise to a pair of spinal nerves. In cross-section (c.s.), the segments appear to be divided into two zones. The outer zone contains many myelinated axons that run up and down the spinal cord.
