Nervous system and brain

5. Chemicals that transmit signals across a synapse from one neuron to another.
6. Receives signals from other neurons
7. Cells in the nervous system that support, nourish, and protect neurons.
9. Releases neurotransmitters to send signals to the next person
15. The part of the brain that coordinates voluntary movements and balance.
16. This hormone regulates the metabolism of carbohydrates, fats, and proteins.
18. The nerve pathway involved in a reflex action.
20. Nerve cell that carries electrical messages
21. This system works with the nervous system to identify odors

1. System This system gives your body its shape and holds your organs in place.
2. The major controlling, regulatory, and communicating system in the body.
3. Rapid change in the electrical charge across a neuron's membrane
4. The brain region controlling the pituitary gland and regulating homeostasis.
8. The junction between two nerve cells where impulses pass.
10. This hormone interacts with the sympathetic nervous system during the fight or flight response.
11. Transmits electrical impulses away from the cell body to other neurons or muscles
12. This carries impulses from all parts of the brain to the body and all parts of the body to the brain.
13. Small gap between the presynaptic and postsynaptic neuron's
14. The largest part of the brain that controls memory and reasoning
17. Store and releases neurotransmitters
19. Maintains the neuron's health and processes incoming signals
