2. the type of muscle that is under voluntary/conscious control
5. specialized cells that send electrical impulses/messages
7. small extensions that receive impulses
10. bypass processing in the brain
12. cells that send processed information to muscles and glands
13. maintains balance and coordination by processing information from muscles around skeleton and joints.
16. a division of the ANS that deals with "rest & digest" responses (e.g., constriction of pupils)
17. and example of a type of muscle that is under involuntary control
19. cells that detect changes from the internal or external environment
21. long extensions that transfer impulses
22. the control center of the NS

1. where the impulse ends in this cell
3. division of a system that deals with involuntary contraction of muscle
4. a collection of axons bundled together blood vessels & connective tissues
6. a system connects the nerves in your body to your spinal cord and brain
8. division of the PNS that deals with voluntary contraction of muscle
9. receives impulses from receptors in blood vessels to regulate blood pressure (also regulates temperature, HR, & breathing)
10. are what the cells contain that allow for detection of changes in the environment
11. a division of the ANS that deals with "fight or flight" responses (e.g., increasing HR)
14. a change in the environment that elicits a response
15. contains the nucleus and organelles
18. the brain and spinal cord are part of this system
19. causes paralysis if this is injured
20. controls voluntary movement, processes different senses and stores memories
