Human Body

6. A substance that stimulates an immune response
8. In the PNS; transmits impulses from the CNS to effector organs, which are the muscles and glands.
12. Protein that inhibits the reproduction of viruses
13. A junction that mediates information transfer from one neuron to the next or from a neuron to an effector cell.
15. The language of the nervous system; by which each neuron communicates with others to process and send messages to the rest of the body.
16. Fluid found in the lymphatic system
17. Consists of nerve fibers that convey impulses to the central nervous system from sensory receptors located throughout the body

1. A cell that engulfs large particles or whole cells
2. An organism that causes disease
3. Cytokine that causes an inflammatory response to an injury; resulting in redness, swelling, warmth and pain.
4. A large white blood cell that engulfs pathogens and cellular debris
5. The structural units of the nervous system, highly specialized cells that conduct messages in the form of nerve impulses from one part of the body to another.
7. Resistance to a certain pathogen
9. Fatty insulating sheath that surrounds all but the smallest nerve fibers.
10. Short, tampering, diffusely branching extensions; receptive regions. Recieves information from other nerve cells and transports it to the soma.
11. Released by white blood cells and macrophages; cause body temperature to increase which prevents bacteria from multiplying
14. Impulse generating and conducting region; neuron process that carries impulses away from the nerve cell body; efferent process; the conducting portion of a nerve cell.
