6. Term meaning a nerve containing both sensory and motor fibers
7. A bundle of fibers located inside the CNS
8. Region of the “H” shaped area of the spinal cord containing the cell bodies of motor nerves
9. The phrenic nerve which supplies the diaphragm is derived from this plexus
11. The part of a spinal nerve which supplies all extremities and lateral and ventral trunk
12. A bundle of neuron fibers which are located outside the CNS
14. A group of nerve cell bodies that lie outside the CNS
16. A swelling of the dorsal root which contains the cell bodies of sensory nerves
19. The third possible part of a spinal nerve which is responsible for the functions of the ANS
20. small hole in the center of the grey matter of the spinal cord, which contains cerebrospinal fluid
22. This structure contains motor nerve fibers only which conduct impulses from the cord to the periphery

1. Regions of the “H” shaped area of the spinal cord containing the cell bodies of sensory neurons
2. The largest nerve in the body
5. Nerves joining together after leaving the vertebral canal
10. Area of the spinal cord which gives rise to the brachial plexus
13. The largest nerve of the Brachial Plexus.
15. lies in the central area of the spinal cord shaped like an “H” or a moth. Contains cell bodies, very few myelinated axons
17. The area of the spinal cord where it tapers to a point caudal to the lumbar enlargement
18. Area of the spinal cord which gives rise to the nerves which supply the pelvic limbs
19. Nerves arising from the lower portion of the cord that do not leave the vertebral column immediately, but run down the vertebral canal resembling hair
