Label cross-section of spinal cord Quiz Information. The spinal cord acts as a conduit for information traveling up and down its length. In the image above, you can see how the central gray matter is somewhat butterfly shaped, with each side of the butterfly containing a posterior (dorsal) horn and an anterior (ventral) horn. In the cortex of the brain, gray matter makes up the cortical (outer) regions, while the white matter tracts tend to make up the majority of the deep tissues of the brain, although there are exceptions to the latter, such as the deep basal and thalamic nuclei that are composed of gray matter. Most vertebrae have an irregular shape, with a large drum-shaped vertebral body on the anterior end and a thin ring-like vertebral arch on the posterior end. Innerbody Research does not provide medical advice, diagnosis, or treatment. Descending nerve signals from the brain pass through the white matter to activate the muscles, glands, and organs of the body, while ascending nerve signals carry sensory information from the tissues of the body to the brain. This website is using a security service to protect itself from online attacks. The ventral roots look like axon streaks against the white matter. The main difference is that the ratio of gray matter to white matter varies among segments of the spinal cord.
