Spinal cord:
When a cross-section of the spinal cord is seen, it appears flat or biophysic in which a small amount of flattening in the ventral part is partially divided from the dorsal side to the right and left hemispheres by the dorsal medial septum and on the ventral side there is a deep incision called the ventral median fissure.
The entire spinal cord is surrounded by a fibrous epithelium called the pia mater, which continues with the abdominal mediastinum and is closely attached to the superficial part of the spinal cord and may find a number of blood vessels.
In the center of the section is an area in the form of letter H darker than the rest of the spinal cord material and this gray matter, the majority of which are the bodies of polypolar neurons called the upper ribs of the gray material in the horns dorsal or posterior horns dorsal or posterior horns and the lower ribs of gray matter in the horns Ventral or anterior horns. The transverse side of the letter H is called the gray commessure. The white matter of the white matter is surrounded by the gray matter and consists mainly of the spinal cord and the nonmachine nerve fibers.
