These original illustrations were produced from medical imaging data reconstructed in 3D and from histological and anatomo-pathological sections of the spinal cord. Viewed in a cross-section, it has a roughly oblong shape with white matter on its exterior and a butterfly-shaped region of gray matter on its interior. At the lower levels of the spinal cord there is a greater ratio of grey matter to white matter. Several shallow furrows (known as sulci) and a deep furrow (known as the anterior median fissure) penetrate the white matter and divide it into several regions. The vertebral column, or spine, is a group of twenty-six stacked vertebrae extending from the skull to the pelvis. An example of a spinal reflex is withdrawing the hand when it detects pain. The white matter of the spinal cord is divided into columns. Determine the ratio of the heat transferred from the 400F400 \mathrm{~F}400F reservoir to the heat transferred from the 20F-20 \mathrm{~F}20F reservoir, assuming all processes are reversible. The posterior root of the nerve carries sensory information into the posterior horn, often synapsing there. The gray matter found here consists of interneurons, neurons, and glial cells, all part of the central nervous system. This area is made up of all the nerve fibers that direct the reflex actions and convey the impulses that go back and forth to the brain. Played. The spinal cord is a central nervous system structure that extends inferiorly from the brain stem and into the lower back. The spinal cord acts as a conduit for information traveling up and down its length. For example, segment S2 of the spinal cord would be located near the T12 vertebrae. When you look at the spinal cord cross section, it almost looks like a taffy candy that has a butterfly right in the middle.

This figure shows other important features of the spinal cord, many of them related to the spinal cords function of relaying information. It is the 31 pairs of spinal nerves and their related structures that provide the pathways for this interaction. Because the spinal nerves contain both sensory and motor fibers, they are considered a mixed nerve, as opposed to either a sensory or motor nerve. The nervous system is critical to many of our homeostatic feedback loops. These areas include: Interesting enough, the spinal cord takes up around 2/3 of the vertebral canal where it rests. At low magnification, differentiate inner gray from outer white matter and identify dorsal and ventral horns of the gray matter. Some of the tracts cross over (decussate) either in the spinal cord or brainstem, and when this occurs, the relationship between the origin and destination is termed contralateral. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.
