Just distal to the intervertebral foramen of the spinal column, the spinal nerve branches into rami (singular: ramus). 50 terms. The integration of sensory information produces spinal reflexes in the spinal cord to cause a motor response to stimuli faster than the distant brain could make the same response. The structure of the spinal cord aids it in carrying out these relaying and integrative functions. You may be surprised to find out that the spinal cord in an adult comes in at about 17 1/4 inches long, is about as wide as your thumb, and is just as thin as a straw that you drink from at the base. The arterial supply of the spinal cord is shown on three different illustrations: an anterolateral view of the thoracic spine showing the emergence of the anterior spinal artery from the root and intercostal arteries), an axial section showing the branches of costal arteries destined for spinal cord and muscle and finally an overview of the arterial vascularisation to understand the substitution networks between the anterior and posterior spinal arteries as well as the role of the anterior segmental medullary artery (Adamkiewicz' artery). When you look at the spinal cord cross section, it almost looks like a taffy candy that has a butterfly right in the middle. The nervous system is critical to many of our homeostatic feedback loops. They are named for the area of the vertebral column from which they come. Every bundle of axons is a tract and it transmits specific information. Play Now. The spinal cord acts as a conduit for information between the brain and the body below the neck. Canadian Provinces Quiz. ninalahoti. In contrast to this general arrangement of the brain, the spinal cord is arranged with the white matter surrounding the central gray matter, indicating that the spinal tracts carry information up and down the cord along the outer aspects, while synaptic transmission tends to occur more centrally. Exiting through a big hole at the bottom of the skull, the spinal cord is covered by the vertebral column that protects it. Note that not all of the spinal nerves arise from the cord at the level of the vertebrae between which they pass. Last Updated 01 March, 2023.

For example, your right arm is mainly controlled by the motor area in your left brain. Sensory and motor fibers enter and exit the cord via rootlets that arise from both the posterior and anterior aspects of the cord. And that is because the vertebral column grows at a rate that is much faster than the spinal cord do,thus the cord will take up less and less room as the person grows. What is the role of the ventral root? Dorsal Horn . In transverse section, the spinal cord is incompletely divided into right and left halves by an anterior (ventral) median fissure and a posterior (dorsal) median sulcus and septum . The vertebra forms a bony protective conduit for the spinal cord while also providing strength and support to the soft tissues of the head, neck, and trunk. All rights reserved. Recall that the central nervous system tissues can generally be divided into white matter and gray matter. Distal to the posterior root ganglion, the fibers of the anterior and posterior root merge together and pass through the dura to become the spinal nerve. 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 is most obvious when considering those spinal nerves arising in the lower lumbar and sacral regions. by korimroberts19.
