  1. 4. The term for thinking
  2. 5. Projections that receive and transmit the impulse toward the cell body
  3. 8. Division of the nervous system that extends beyond the brain and spinal cord
  4. 10. The impulses sent by the nerve cells to muscles and glands; includes muscle contractions and reflexes, glandular secretions, changes in hormone levels or activation of immune reactions
  5. 11. Division of the nervous system that includes the brain and spinal cord
  6. 13. Receive stimuli from the external environment
  7. 15. Impulse-conducting cells that are the simplest units of the nervous system
  8. 17. Type of receptor that detects chemical stimuli
  9. 19. Type of sensory neuron that transmits the impulse toward the CNS
  10. 21. Sensory ___________ is the gradual decrease in receptor responsiveness to a constant or prolonged stimulus
  11. 22. Type of receptor that detects actual or potential tissue damage and serves as a protective function
  12. 23. When nerve cells detect internal or external stimuli and transmit the information to the brain and spinal cord
  13. 24. Type of receptor that detects pressure and soundwaves
  14. 27. Type of neuron that transmits an impulse between the sensory and motor segments of the nervous system
  15. 28. Division of the autonomic nervous system that controls energy expenditure and is referred to as "fight or flight"
  16. 29. Ability of a neuron to release a neurotransmitter
  17. 30. Ability of a neuron to transmit an impulse along the length of their axon and on to other neurons, muscles, or glands

  1. 1. Subdivision of the peripheral nervous system that regulates involuntary activities of organs, glands, and smooth muscle
  2. 2. The basic structures of the nervous system include the brain, spinal cord, cranial and spinal nerves, sense organs, and
  3. 3. Chemical messengers that are released by synaptic vesicles upon arrival of a nerve impulse
  4. 6. Type of receptor that detects light stimuli
  5. 7. Contains the nucleus and other organelles
  6. 9. Type of motor neuron that transmits the impulse away from the CNS
  7. 12. Ability of a neuron to respond to a stimulus and produce an impulse
  8. 14. Division of the autonomic nervous system that controls energy conservation and is referred to as "rest and digest"
  9. 16. Receive stimuli from the internal environment
  10. 18. Type of receptor that detects changes in electrolyte concentrations in blood plasma
  11. 20. Type of receptor that detects changes in environmental temperature
  12. 25. The most common neurotransmitter
  13. 26. Projection that transmits the impulse away from the cell body
  14. 29. Subdivision of the peripheral nervous system that transmits sensory input and controls the voluntary function of skeletal muscles
