1. Once the impulse continues to travel through the interneurons to the brain. (For a reflex, it just goes to the spinal cord.) ..... What happens next?
2. Division of ANS that regulates resting and nutrition-related functions such as digestion, defecation, and urination
3. Chemicals in the air are detected by
4. Homeostasis is maintaining a ..... internal environment.
5. ..... is a part of the nervous system that includes the brain and spinal cord
6. Which part of the brain is responsible for balance?
7. Which part of a neuron receives messages?
8. Which part of the nervous system that allow communication with rest of the body?
9. Which of the following neuroglia (glial cells) is NOT found in the CNS?
10. What cells help to detect colors?
11. The nerves that send messages from the body to the brain and spinal cord are called ..... nerves.
12. What is the function of cerebrospinal fluid in the brain?
13. Hormones cause specific effects by .....
14. Identify the neuroglia described:Regulates cerebrospinal fluid
15. Which organ is like a highway system where INFORMATION travels all throughout body?
16. A biological scientist would most likely research .....
17. What part of the Motor (efferent) division is in control of voluntary movement?

27. Name the two major parts of the central nervous system.
28. Nerve cells responsible for receiving external stimuli from the body's environment and passing that signal through nerves to the Central Nervous System.
29. A dramatic change/ depolarization past-55 mV initiates an ..... in a neuron and causes a neural transmission.
30. Passes the signal on to the interneuron in the spinal cord
31. The "bumps" on the surface of the brain are called .....
32. Which part of the nervous system detects changes inside and outside the body?
33. What type of memory would be affected by a lesion to the hippocampus?
