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