Across
- 4. An insulating layer of fat coating some neurons.
- 6. The area of the brain that controls automatic functions.
- 10. That area of the brain responsible for processing vision.
- 11. Projections of the neuron that carry impulses to the cell body.
- 12. Fluid that freely flows around the brain, around the spinal cord, and back to the brain, whose function is to protect the brain by acting as a shock absorber.
- 16. Immune cells that mature in the thymus
- 17. An event that causes a sensory nerve to generate an impulse.
- 20. Receiving antibodies from another individual; donor or mother to baby
- 24. An elevation in body temperature above the normal 98.6 degrees F
- 26. A complex system that protects us from infectious organisms
- 29. A non-specific response occurring in reaction to an injury to tissues as a way to further protect the body from infection
- 30. An artificial way to filter the blood for patients with kidney failure
- 31. The outer 4mm of the brain and the interior of the spinal cord which appears grey. This is where all of the axon cell bodies are located.
- 32. Lymphocytes that produce antibodies; plasma cells
- 33. A part of the hindbrain that helps to coordinate involuntary actions.
Down
- 1. The sensory and motor nerves in the body and extremities.
- 2. The part of the brain that is responsible for hearing and processing speech.
- 3. The brain and spinal cord.
- 5. That area of the brain responsible for processing sensory information.
- 7. lobe The lobe of the brain responsible for thinking and planning to move the body.
- 8. An individual nerve cell.
- 9. The waste products left in the urinary system after all the wastes are filtered out and the needed materials (water and ions) are reabsorbed
- 13. Immunity to a specific pathogen that develops after becoming infected by a pathogen or receiving a vaccine
- 14. The largest projection of the neuron, responsible for carrying all impulses out and away from the nerve cell.
- 15. A chemical that causes blood vessels to dilate and increase blood flow to the tissue in the area
- 18. The area of the brain and spinal cord that appears white due to the high concentration of myelinated axons it contains.
- 19. The direct connection between the brain and the endocrine system.
- 21. A property of the immune system in which it "remembers" the specific pathogens it has been exposed to in the past so the pathogen can be cleared quickly if re-exposed.
- 22. Gland located just below the hypothalamus (brain) that releases various types of hormones upon stimulation by the hypothalamus
- 23. The part of the midbrain that relays sensory information.
- 25. Nervous tissue that controls automatic functions.
- 27. Light sensitive cells that allow for vision in low levels of light, but are not able to process color.
- 28. The functional unit of the kidney
