Across
  1. 4. the chief motor nerve of the face; also known as facial nerve.
  2. 5. sensory-motor nerve that, with its branches, supplies impulses to the fingers
  3. 6. the largest artery in the body
  4. 7. the largest and most complex nerve tissue in the body; controls sensation, mucsles, activity of glands, and the power to think, sense, and feel.
  5. 8. double-layered membranous sac that encloses the heart; made of epithelial tissue
  6. 9. structures that temporarily close a passage or permit blood flow in only one direction
  7. 11. an automatic reaction to a stimulus that involves the movement of an impulse from a sensory receptor along the sensory nerve to the spinal cord.
  8. 12. sensory-motor nerve that is smaller than the ulnar and radial nerves and that, with its branches, supplies the arm and the hand.
  9. 14. the valve between the right atrium and left ventricle of the heart; also known as bicuspid valve
  10. 15. small vessel that connects the capillaries to the veins
  11. 16. affects the muscles of the chin and lower lip.
  12. 19. small vessel that connects the capillaries to the veins
  13. 20. extension of a neuron through which impulses are sent away from the cell body to other neurons, glands, or muscles.
  14. 23. sensory nerve endings located close to the surface of the skin.
  15. 24. supplies blood to the muscles of the eye
  16. 26. main arteries that supply blood to the face, head, and neck
  17. 28. primary structural unit of the nervous system; also known as nerve cell
  18. 30. complex iron protein that gives blood its color
  19. 31. supplies blood to the side of the nose.
  20. 32. tree-like branchings of nerve fibers extending from the nerve cell that carry impulses toward the cell and receive impulses from other neurons.
  21. 33. a lower, thick-walled chamber that receives blood from the atrium
  22. 34. supplies impulses to the skin on the outer side and back of the foot and leg.
  23. 35. main blood supply to arms and hands
Down
  1. 1. also known as leukocyte
  2. 2. located in the back of the head; affects the scalp as far up as the top of the head
  3. 3. controls the voluntary functions of the five senses
  4. 8. its function is to carry impulses to and from the central nervous system
  5. 10. the portion of the central nervous system that originates in the brain and extends down to the lower extremity of the trunk; protected by the spinal column.
  6. 12. affects the skin of the lower lip and chin
  7. 13. thin-walled blood vessel; less elastic and located closer to the skin's surface than arteries
  8. 17. main blood supply to arms and hands
  9. 18. flows from the body into the right atrium
  10. 21. extends down the front of the leg; also known as anterior tibial nerve
  11. 22. main nasal muscle of concern to cosmetologists
  12. 25. largest cranial nerve; also known as trifacial or trigeminal nerve
  13. 27. the largest and longest nerve in the body.
  14. 29. the scientific study of the structure, function, and pathology of the nervous system
