Next, the user will find anatomical sections of the spinal cord at different levels: cervical spinal cord (C2, C5), thoracic spinal cord (T10), lumbar spinal cord (L3) and sacral spinal cord (S3). The spinal cord is a nervous system structure dedicated to relaying information from the periphery to the brain and back, as well as carrying out certain levels of integration, such as those found in many reflexes. All rights reserved. English. The four main plexuses are the cervical, brachial, lumbar and sacral. The specific horns of the gray matter are responsible for different things. IMAIOS is a company which aims to assist and train human and animal practitioners. You should also identify the dorsal and ventral horns in slide 65-1N stained with Masson trichrome. Cross-section of spinal cord displays grey matter shaped like a butterfly surrounded by a white matter. Each of these regions, or columns, contains thousands of axons traveling between the brain and the bodys tissues. Then, two axial sections of the spinal cord and adjacent structures allow the organisation of a spinal nerve to be displayed with its various branches (sensitive posterior root, anterior motor root, meningeal branch, muscular branches, intercostal nerves) and represent the different spaces and meninges covering the spinal cord (epidural space, subdural space, subarachnoid space, pia mater, spinal dura, arachnoid spinal). Carries motor information from the spinal cord to the rest of the body and leaves from the anterior side of the cord. The gray matter of the dorsal horns is thinner than the ventral horns.The dorsal roots can be cut in the cross section and come out from the horn area. You may note from its name that it is an ascending tract, so the information that it carries is sensory. The Schwann cell wraps around the axon to envelop it in a myelin sheath that functions as an electrical insulator. sammiesadler1 Plus.

These are unipolar neurons, such that their dendrites extend out to the peripheral tissues, and their axons project into the dorsal horn of the spinal cord, where they synapse. The central canal is filled with cerebrospinal fluid, which circulates from the ventricles of the brain to the central canal and around the surface of the spinal cord. You can freely give, refuse or withdraw your consent at any time by accessing our cookie settings tool. Because the spinal cord terminates near vertebrae L1, and there is a lot of body tissue that needs to be innervated below this level, there are a significant number of nerves arising from the lower aspect of the spinal cord. When the origin and destination of a tract are on the same side of the body, it is referred to as an ispsilateral relationship. This neuron projects its axon via a descending white matter tract to a point in the spinal cord where it synapses in the ventral horn with a lower motor neuron. You can move the markers directly in the worksheet. Cross-sectional anatomy. The spinal cord is made up of 31 segments. This electron micrograph shows a cross section of a myelinated nerve in the peripheral nervous system. The spinal cord is a central nervous system structure that extends inferiorly from the brain stem and into the lower back. Motor neurons exit the spinal cord through the anterior roots of the spinal nerves, so they are found in the anterior and lateral horns. The nervous system is critical to many of our homeostatic feedback loops. The white matter is subdivided into dorsal (or posterior), lateral, and ventral (or anterior) columns. The anterior horn contains the cell bodies of somatic motor neurons, and it sends its axons out the anterior root of the spinal nerve to the muscle cells it innervates. The anatomy of the grey matter of the spinal cord is summarized on a diagram with the various grey matter nuclei (note that this representation is virtual because some nuclei are only present at some levels between them but are displayed on a single cross-sectional diagram).
