A layer of epidural adipose tissue fills the space between the dura mater and the vertebra and acts as a shock absorber for the spinal cord. Cerebrospinal fluid flows around the pia mater in the hollow subarachnoid space beneath the second layer of meninges, the arachnoid mater. Below the medullary cone, the vertebral canal contains a bundle of nerve roots called the cauda equina. . Please include what you were doing when this page came up and the Cloudflare Ray ID found at the bottom of this page. #2. You may note from its name that it is an ascending tract, so the information that it carries is sensory. The butterfly-shaped gray matter extends from the central canal anteriorly to form the anterior gray horn, laterally to form the lateral gray horn, and posteriorly to form the posterior gray horn. 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. The spinal cord runs through the vertebral foramen, a hollow tube running the length of the spinal column. 208.113.148.196 You can consent to the use of these technologies by clicking "accept all cookies". A small, circular tube-like cavity known as the central canal sits in the center of the gray matter. The ventral roots look like axon streaks against the white matter. 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. RachaelHG1. 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. You can move the markers directly in the worksheet. The innermost layer of meninges, the pia mater, covers the surface of the spinal cord and contains many blood vessels to support the spinal cords tissues. It starts with an upper motor neuron, whose cell body is in the cerebral cortex or gray matter of the brainstem. Your IP: 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 second illustration of the spinal cord schematised in 3-dimensions the white matter cords, the grey columns and the horns of the spinal cord. Exiting through a big hole at the bottom of the skull, the spinal cord is covered by the vertebral column that protects it.
