Human Biology

2. usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell.
4. that stimulates or acts as an incentive
7. Feedback:Feedback that reduces the output of a system, such as the action of heat on a thermostat to limit the output of a furnace or the accumulation of toxic waste products by a growing population of bacteria.
8. Of, at, relating to, or forming a limit, boundary, extremity, or end.
9. trilobed structure of the brain, lying posterior to the pons and medulla oblongata and inferior to the occipital lobes of the cerebral hemispheres, that is responsible for the regulation and coordination of complex voluntary muscular movement as well as the maintenance of posture and balance.
13. An agent, especially a chemical agent such as caffeine, that temporarily arouses or accelerates physiological or organic activity.
14. junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell.
16. Cells:a visual receptor cell that is sensitive to dim light.
17. capacity for or the practice of recognizing and respecting the beliefs or practices of others.
18. System:The bodily system that consists of the endocrine glands and functions to regulate body activities.

1. process by which a system, often biological or ecological, is modulated, controlled, or changed by the product, output, or response it produces.
3. to lower the rate of vital physiological activities.
5. of the impulse-conducting cells that constitute the brain, spinal column, and nerves, consisting of a nucleated cell body with one or more dendrites and a single axon.
6. Large and impressive in size, scope, or extent
10. Arc:The neural path of a reflex.
11. portion of the brain, consisting of the medulla oblongata, pons Varolii, and midbrain, that connects the spinal cord to the forebrain and cerebrum.
12. System:The system of cells, tissues, and organs that regulates the body's responses to internal and external stimuli. In vertebrates it consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs.
15. Cells: visual receptor cell in the retina that is sensitive to bright light and to color.
