Second, the vertebra protects the delicate tissues of the spinal cord by surrounding it with hard bone tissue. by korimroberts19. Another function of the spinal cord is maintaining muscle tone and producing reflexes. As previously mentioned, the lateral horns are only found in the thoracic and lumber regions of the spinal cord, where they contain the motor nuclei of the sympathetic nervous system. Innerbody Research does not provide medical advice, diagnosis, or treatment. For example, segment S2 of the spinal cord would be located near the T12 vertebrae. They are named for the area of the vertebral column from which they come. For example, the thoracic segments have relatively small anterior horns, as there is little skeletal muscle to innervate in the thorax and abdomen, while the cervical and thoracolumbar regions have large anterior horns, used to innervate the skeletal muscles of the arms and legs, respectively. Grey matter consists of the central canal at the centre and is filled with a fluid called CSF (Cerebrospinal fluid). Below the medullary cone, the vertebral canal contains a bundle of nerve roots called the cauda equina. Get 22% Off before it's gone >>. ), the segments appear to be divided into two zones. This is because the lateral horns contain the neurons of the sympathetic nervous system, which leave the cord only in these segments. they contain efferent fibers) while the posterior rootlets carry sensory information into the spinal cord (i.e. When the origin and destination of a tract are on the same side of the body, it is referred to as an ispsilateral relationship. The nerve roots for these nerves arise from the spinal cord at, or near, the medullary cone, which you will recall is near the L1 vertebrae. Basically the spinal cord is responsible for: Here's is a video explaining clearly about the spinal cord: Copyright WWW.NEWHEALTHADVISOR.ORG 2014, All rights Reserved. It consists of horns (four projections) and forms the core mainly containing neurons and cells of the CNS. The lateral horn is not found at all levels of the spinal cord, but is limited to thoracic and lumber segments of the cord. 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. 240 plays. Open menu. Recall during development, newly formed neurons proliferate adjacent to the canal to form a mantle layer, which becomes the gray matter in the central region of the mature spinal cord.

The tracks that move upward are responsible for signals to the brain and the descending tracts send the signals from the brain to neurons throughout the body. Cerebrospinal fluid flows around the pia mater in the hollow subarachnoid space beneath the second layer of meninges, the arachnoid mater. Sensory and motor fibers enter and exit the cord via rootlets that arise from both the posterior and anterior aspects of the cord. 4. anterior column (white matter) posterior root of spinal cord. Include SEVERAL cross-sections of mostly axons of the neurons. Because the spinal nerve roots dont always originate at the level of the vertebrae that they pass through, the segments of the spinal cord are named for the spinal nerve to which they give rise. Consider a river flowing toward a lake at an average velocity of 3 m/s at a rate of 500 m^3/s at a location 90 m above the lake surface. 55. Give it a try! For clearer demonstration of the spinal cord cross section, watch the video below: The white matter has the nerve fibers that run up and down the length of the cord, they are called axons.

Although each segment of the spinal cord has similar features, there are some differences along its length, as you may be able to determine from the image above. 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. Almost all nerve signals traveling to and from the body below the head pass through the spinal cord, making it the information superhighway of the body. The white matter of the spinal cord is divided into the paired posterior (dorsal), lateral, and anterior (ventral) columns. The ascending tracts generally carry sensory information from the periphery to the brain, while the descending tracts carry motor signals to muscles and glands. 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. This is a printable worksheet made from a PurposeGames Quiz. IMAIOS is a company which aims to assist and train human and animal practitioners. The spinal cord, which consists of the major nerve tract of vertebrates, runs down from the bottom of the brain through the passageway of the spinal column. Recent flashcard sets. 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. It is the 31 pairs of spinal nerves and their related structures that provide the pathways for this interaction. At this rate, the spinal cord will only extend up to the first lumbar vertebrae by the time a person reaches adulthood. Anterior Median Fissure . Peter A Brennan MD, PhD, FRCS (Eng), FRCSI, Hon FRCS, FFST RCS (Ed), FDSRCS, in Gray's Surgical Anatomy, 2020.
