Across
  1. 3. process of neurotransmitters molecules recycles back to the presynaptic neuron.
  2. 5. vesicles packed neurotransmitter molecules.
  3. 6. process of molecules flowing from areas of high and low concentration.
  4. 7. is a nerve cell. These nerve cells are a primary part of the nervous system. The nerve cells are responsible for transmitting information throughout the body.
  5. 8. the ____ neuron where the signals are coming from.
  6. 10. cleft small separation between neurons.
  7. 12. allows electrical signals to transmit quickly.
  8. 13. the strong signals from the dendrites get sent here and become an action potential.
  9. 15. potential travels down the axon.
  10. 16. cells Highly interconnected.
Down
  1. 1. cortex The outermost layer of the brain. It is made up of two hemispheres joined in the middle by nerve fibers.
  2. 2. Responsible for receiving chemical signals from other neurons by their receptors.
  3. 4. the ____ neuron that receives the signals from neurons.
  4. 9. interprets chemical signals picked up by the dendrites which cause electrical changes in the neuron.
  5. 10. an area where two neurons meet to pass chemical signals.
  6. 11. chemical signals from neurons through the receptors of dendrites.
  7. 14. terminals releases neurotransmitters to interact with the next neuron.
