Label cross-section of spinal cord Quiz Information. In most of these loops, the structures of the nervous system make up more than one component, and carry out more than one function in these loops. 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. All Rights Reserved. Lateral Horn . Each pair is also connected by a commissure of white matter that runs adjacent to the gray commissure, termed the anterior and posterior commissures. The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white 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. Rootlets . Finally, the size of the anterior and posterior horns varies, depending on the amount of tissue they are innervating. A plexus is a network of anterior rami from neighboring spinal nerves that come together in a weblike or tangled network adjacent to the spinal cord, and from which new nerves arise.

At low magnification, differentiate inner gray from outer white matter and identify dorsal and ventral horns of the gray matter. Second, the vertebra protects the delicate tissues of the spinal cord by surrounding it with hard bone tissue. In general, the posterior ramus communicates with structures posterior to the cord, while the anterior ramus communicates with structures anterior to the cord. Expert Answer. Each of these regions, or columns, contains thousands of axons traveling between the brain and the bodys tissues. Extending from the posterior of the vertebral body is the vertebral arch, which surrounds the spinal cord. Significant Figures and Scientific Notation, Functional Divisions of the Nervous System: CNS. The columns are further divided into tracts that carry sensory information up the spinal cord (ascending tracts) and motor information down the spinal cord (descending tracts).
