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