Across
  1. 2. – Branch-like parts of a neuron that receive messages.
  2. 5. – A long fiber that sends messages away from the neuron.
  3. 8. – A neurotransmitter that affects mood, sleep, and emotions.
  4. 10. Potential – The electrical signal sent through a neuron.
  5. 11. Neuron – A neuron that carries signals from the brain to the muscles.
  6. 12. Transmission – The process of sending messages between neurons using neurotransmitters.
  7. 13. Psychology – The study of how biology influences thoughts, emotions, and behavior.
  8. 14. Vesicles – Tiny sacs in axon terminals that store neurotransmitters.
  9. 15. – A neurotransmitter linked to pleasure, motivation, and movement.
  10. 16. – A neuron that connects other neurons within the brain and spinal cord.
  11. 19. Body – The main part of a neuron that contains the nucleus.
  12. 20. Sheath – A fatty layer that covers and protects the axon, speeding up signals.
  13. 21. – The process where neurotransmitters are taken back into the neuron after a signal is sent.
  14. 23. – The space where neurons pass messages to each other.
Down
  1. 1. – A neurotransmitter that helps with muscle movement and memory.
  2. 3. – The minimum level of stimulation needed for a neuron to send a signal.
  3. 4. Terminals – The ends of a neuron where signals are sent to the next cell.
  4. 6. – The scientific study of the brain and nervous system.
  5. 7. Potential – The state of a neuron when it is not sending a signal.
  6. 9. – Something that causes a response in the body.
  7. 14. Neuron – A neuron that carries signals from the senses to the brain.
  8. 17. – Chemicals that carry messages between neurons.
  9. 18. Cells (Glia) – Support cells that help neurons function.
  10. 22. – Nerve cells that send and receive messages in the body.
  11. 23. Gap – The tiny space between two neurons at a synapse.
