Nervous System

3. All the nerves outside the CNS. It connects the CNS to the body's muscles, skin, and organs.
4. The chemical messenger that jumps across the synapse to carry the signal from one neuron to the next cell.
7. The branch-like arms of a neuron that receive messages (signals) from other neurons.
9. Neurons that carry command signals AWAY from the CNS to muscles and glands, telling them to move or act.
10. Part of the brain that regulates your sleep.
12. The long, thin tail of a neuron that sends the message away from the cell body to the next cell.
15. The largest part of the brain that controls conscious thought, voluntary movement, and senses.
16. Information being received by your 5 senses.
17. Neurons that carry information from the senses (eyes, skin, etc.) TOWARD the CNS (the brain/spinal cord).
20. The rapid electrical signal that travels down a neuron (the actual message).
22. The tiny gap or meeting point between two neurons where they communicate.
23. Controls your hunger and emotions.
24. Ms. Ruiz's favorite color.
25. The movement or action that is made from a brain command.

1. The division of the PNS that runs on "auto-pilot."
2. This is the step where the information received from sensory input is processed.
5. The main organ of the CNS, responsible for thought, memory, emotion, and controlling the body.
6. Regulating conditions inside an organism.
8. Connects the brain to the spinal cord. It controls vital, involuntary functions like breathing and heartbeat.
11. A fatty coating around the axon that speeds up the nerve message.
13. Cell that sends messages (electrical/chemical signals) throughout the body.
14. The body's control center and communication network (like an electrical grid).
18. The main command center of the nervous system. It includes the Brain and Spinal Cord.
19. A thick bundle of nerves running down the back.
21. The part of the brain at the back that helps coordinate smooth muscle movement and balance.
