1. List the 3 spinal meninges and three associated spaces. Next to each, describe its structure. 2. For each of the following structures, indicate which part of which type of neuron is found in the structure. As an example, I have provided an example for the anterior root: - posterior horn - lateral horn - anterior horn - posterior column - lateral column - anterior column - posterior root - anterior root - axons of motor neurons - posterior root ganglion 3. List the 3 types of connective tissues found in nerves and indicate which structure it surrounds. 4. Give a description of each of the following external structures of the spinal cord: - cervical enlargement - lumbar enlargement - cauda equina - conus medullaris - filum terminale 5. List the 4 major plexuses. For each plexus, list the spinal nerves that contribute nerve fibers to the plexus and the major nerves that emerge from the plexus.

Interneurons Neurons that connect sensory and motor neurons Part 2: Copy the number for each question and indicate whether each of the following statements is true or false. 1. The cerebellum is the largest part of the brain. False 2. The pons is located below the medulla oblongata. True 3. The hypothalamus controls urges such as thirst and hunger. True 4. The corpus callosum controls most thinking and reasoning processes. True 5. Motor neurons will carry an impulse toward the central nervous system. True 6. The dorsal root of the spine's vertebrae has sensory neurons passing through. True 7. The hypothalamus produces several hormones that are stored in the pituitary gland. True 8. The hypothalamus usually involves the peripheral nerves and the spinal cord. False 9. A reflex lobe of the brain controls vision. False 10. The temporal lobe of the brain controls hearing. True 11. The frontal lobe controls respiration. False 12. The autonomic nervous system is part of the sympathetic nervous system. True 13. The hindbrain connects with the forebrain. False 14. The midbrain connects the nervous system.
