Question 49 Match each term to its definition. Lies between the arachnoid mater and pia mater, and is filled with cerebrospinal fluid Contains fibers that carry sensory information into the spinal cord The innermost layer of the meninges Small space between the outer covering of the spinal cord and the vertebrae Contains fibers that carry motor information out of the spinal cord Tough outer layer of the meninges A single nerve that contains both motor and sensory fibers Carries cerebrospinal fluid through the spinal canal

Part A: Match the term with its correct description 1. Carries sensory impulses toward spinal cord - A. Dura mater 2. Carries motor impulses away from spinal cord - B. Arachnoid mater 3. Carries both sensory and motor impulses - C. Pia mater 4. Tough outer covering of brain and spinal cord - D. Subdural space 5. Layer of meninges attached to the surface of the brain and spinal cord - E. Subarachnoid space 6. Middle layer of meninges - F. Cauda equina 7. Consists of myelinated axons - G. Conus medullaris 8. Includes posterior, anterior, and lateral horns - H. Cervical enlargement 9. Tapered end of the spinal cord - I. Lumbar enlargement 10. Gives rise to nerves that serve the upper limbs - J. Spinal nerve 11. Gives rise to nerves that serve the lower limbs - K. Posterior (dorsal) root 12. Space between the dura mater and arachnoid mater - L. Anterior (ventral) root 13. Space between the arachnoid mater and pia mater - M. Gray matter 14. Nerves extending downward from the conus medullaris - N. White matter 15. Carries cerebrospinal fluid down the center of the spinal cord - O. Central canal
