Across
  1. 3. Division transmits impulses from sense organs to the central nervous system
  2. 4. 26 small bones that make up your backbone
  3. 6. Impulse the message carried by a neuron
  4. 7. Nervous System the sensory and motor neurons that connect the central nervous system to the rest of the body
  5. 9. Stem Connects the brain and spinal cord
  6. 11. Nervous System is the division of the peripheral nervous system that controls the body's skeletal muscles
  7. 12. Pump is a carrier protein that uses ATP to actively transport sodium ions out of a cell and potassium ions into the cell
  8. 16. Division carries signals from the CNS to gland and muscle cells that carry out the body's responses
  9. 17. Area of the brain responsible for all voluntary activities of the body
  10. 19. are the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
  11. 21. is the extension of a neuron, ending in branching terminal fibers, through which messages pass to other rows or to muscles or glands
  12. 22. A large structure of the hindbrain that controls fine motor skills.
  13. 23. Potential is the brief wave of positive electrical charge that sweeps down the axon
  14. 24. Cord Nerves run up and down the length of the back and transmit most messages between the body and brain
Down
  1. 1. chemical messengers that cross the synaptic gaps between neurons
  2. 2. the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
  3. 5. Potential The difference in electric charge between the inside and outside of a neuron's cell membrane
  4. 8. Nervous System is the division of the autonomic nervous system that calms the body, conserving its energy
  5. 10. positively and negatively charged atoms
  6. 13. Terminal The endpoint of a neuron where neurotransmitters are stored
  7. 14. bundled axons that form neural "cables" connecting the central nervous system with muscles, glands, and sense organs
  8. 15. Nervous System brain and spinal cord
  9. 18. The mass of nerve tissue that is the main control center of the nervous system
  10. 20. Nervous System the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations
  11. 23. Nervous System is the part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms.
