  1. 1. Nerve cell; sends messages through the nervous system.
  2. 2. Neuron A neuron having a motor function; an efferent neuron conveying motor impulses.
  3. 3. Anything that an organism can sense; usually refers to a change that causes an organism to do something in response; piural is stimile.
  4. 6. All the cells and tissue in the body considered collectively, with the exception of germ cells.
  5. 8. Any of the cordlike bundles of fibers made up of neurons through which sensory stimili and moter impulses pass between the brain of other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body.
  6. 9. Neuron Any neuron having a sensory functon, an afferent neuron conveying sensory impulsus. The first in an afferent pathway is the primary sensory.
  7. 10. An animal and / or human'sautomatic response to a stimulis, such as jurking away from a hot surface.

  1. 1. System System of organs and tissues that controls and coordinates the bodys activities.
  2. 4. Muscle Smooth and cardiac muscle, not under concious control.
  3. 5. The junction accross which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell.
  4. 7. A tissue composed of fibers capable of contracting to effect body movement.
  5. 12. Cord Bundle of nerves that goes from the brain stem down to the center of the backbone.
  6. 13. Short extension of the nerve cell body that receives stimuli from the axons.
  7. 15. nervous system The part of the nervous system of vertebrates that contriles involuntery actions of the smooth muscles, hart and glands.
