Nervous System Anatomy

3. responsible for reflex actions such as chewing, tasting, and saliva production
5. thick, tough, outer layer of meninges
10. this is responsible for reasoning, thought, memory, judgment
11. section between the cerebrum and midbrain
12. membrane that contains blood vessels that nourish the nerve tissue
14. nerves that carry messages from all parts of the body to brain and spinal cord
15. carry impulses toward the cell body
17. lipid covering of of axons
19. chemicals that allow nerve impulses to pass from one neuron to another
21. part of nervous system that consists of the brain and spinal cord
22. division of PNS that carries messages between CNS and the body
23. oblongata regulates heartbeat, respiration, swallowing, coughing, and blood pressure
24. branch of nervous system that prepares the body to act (fight or flight response)
26. contains the sympathetic and parasympathetic nervous systems

1. regulates the autonomic nervous system, temperature, appetite, water balance,sleep
2. hollow spaces that connect with each other and with the space under the arachnoid membrane
4. 3 membranes that cover and protect the brain and spinal cord
6. space between axons and dendrites
7. membrane that allows space for fluid to flow between layers
8. part of nervous system that consists of the nerves
9. branch of nervous system that slows the heart rate, decreasing respiration and blood pressure (rest and digest response)
10. responsible for muscle coordination, balance, posture, muscle tone
13. conducts impulses between brain parts and for certain eye and auditory reflexes
16. serves as a shock absorber and carries nutrients to parts of brain and spinal cord
18. carry impulses away from the cell body
19. basic structural unit of the nervous system
20. branch of nervous system consisting of 12 pairs of cranial nerves and 31 pairs of spinal nerves
25. relay center that directs sensory impulses to cerebrum
