Smith, Susan J. Mitchell. Motor neurons exit the spinal cord through the anterior roots of the spinal nerves, so they are found in the anterior and lateral horns. At the lower levels of the spinal cord there is a greater ratio of grey matter to white matter. In the cortex of the brain, gray matter makes up the cortical (outer) regions, while the white matter tracts tend to make up the majority of the deep tissues of the brain, although there are exceptions to the latter, such as the deep basal and thalamic nuclei that are composed of gray matter. This is a printable worksheet made from a PurposeGames Quiz. The white matter of the spinal cord is divided into the paired posterior (dorsal), lateral, and anterior (ventral) columns. 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. Interneurons that connect the sensory and motor neurons are found in the center of the gray matter between the horns. 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. Click the card to flip Flashcards Learn Test Match Created by Mjespo125 Terms in this set (12) dura mater This layer above the arachnoid is the? 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. This should make sense, as there are less ascending and descending tracts of whiter matter as you move lower. Cross-sectional anatomy. This quiz is filed in the following categories.
