Cross Section Of Spinal Cord With Tracts

At the back are two dorsal horns and away from the back are two ventral horns.

Cross section of spinal cord with tracts. The spinal cord has grey matter inside and appears h shaped in cross section. White matter surrounds the gray matter and is made of axons. Looking at a cross section of the spinal cord you would see gray matter shaped like a butterfly surrounded by white matter.

Internal to this peripheral region is the grey matter which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly shape. The part of the grey matter that penetrate the white matter is called as horn ie dorsal ventral and lateral horns. Ascending and descending tracts of the spinal cord.

The white matter in each half of the spinal cord is into four columns the funicle. Like the brain the spinal cord is covered by three connective tissue envelopes called the meninges the space between the outer and middle envelopes is filled with cerebrospinal fluid a clear colourless fluid that cushions the spinal cord. As the name suggests the ascending tracts of the spinal cord ascend from the spinal cord and connect it to the brain.

It shows anterior lateral and posterior horns. The spinal cord has a central core of gray matter that looks somewhat butterfly or h shaped in cross sections. It contains pathways that connect the brain with the rest of the body.

Spinal cord cross section. The core consists mainly of two posterior dorsal horns which extend toward the posterolateral surfaces of the cord and two thicker anterior ventral horns which extend toward the. In cross section the peripheral region of the cord contains neuronal white matter tracts containing sensory and motor axons.

Spinal cord cross section the gray matter is the butterfly shaped central part of the spinal cord and is comprised of neuronal cell bodies. A cross section of the spinal cord reveals white matter arranged around a butterfly shaped area of gray matter.
