Spinal Cord, Spinal Nerves and Spinal Reflexes Study Guide 1. Distinguish between the central and peripheral nervous systems and their main components. 2. Discuss the structure and functions of the spinal cord, and describe the three meningeal layers that surround the central nervous system. 3. Identify and define the role of the major regions of the white and gray matter in processing and relaying sensory information and motor commands of the spinal cord. 4. Describe the major components of a spinal nerve, and relate the distribution pattern of spinal nerves to the regions they innervate. Explain how the varicella-zoster virus affects the peripheral nervous system to cause shingles, which manifests in a painful rash in a dermatomal pattern. 5. Discuss the significance of neuronal pools, and describe the major patterns of interaction among neurons within and among these pools (divergence, convergence, serial processing and parallel processing. 6. Describe the steps in a neural reflex, and classify the types of reflexes. 7. Distinguish among the types of motor responses produced by various reflexes (stretch, tendon, withdrawal, and crossed extensor), and explain how reflexes interact to produce complex behaviors. 8. Explain how higher centers control and modify reflex responses to facilitate and inhibit reflexes.
