1. NERVOUS SYSTEM
Coordinates all activities in the body by transmitting messages back and forth to every cell of the body through _________________.

2. Central Nervous System
_______________ and ______________
Receives messages from the PNS (__________________________________________________________________) and sends a response or reaction.
Tells the body how to ______________________________________

3. _________________ About 18 +/- inches
Sends messages from __________________________ to ________________________ and visa versa.

4. Brain
_______________________________________________________________________________________________________________
Allows you to think, reason, coordinate, learn, remember, perform all bodily functions whether voluntary or involuntary

5. Brain Parts
______________
_______________

6. Cerebrum LARGEST, most complex part of brain
Controls __________________________________________________________________________
______________side controls the left side of the body
______________ side controls the right side of the body

7. Cerebrum Lobes ________________ Lobe _____________ Lobe

8. Frontal Lobe Voluntary ______________ Use of _________________

9. Parietal Lobe Sensory Information _____________
_____________—where your body is and what it is doing

10. Occipital Lobe
__________________

11. Temporal Lobe
_________________

12. ___________________________
Coordinates movement of the skeletal muscles
Posture
Balance

13. Brain Stem
3-inch stalk of nerve cells and fibers that connect the __________________________________________________________________________
The “Gateway” from the brain to the body and the body to the brain

14. Brain Stem Parts _______________________ ____________________ Thalamus
Hypothalamus

15. Medulla Oblongata The lowest portion of the brain stem
Regulates _____________________ rate
Regulates hearing, talking, and swallowing
Regulates reflexes such as:
______________________

16. Pons Sits just above the M.O.
Connects nerve impulses to other parts of the ______________________
Helps breathing
Controls muscles of the ________________________________

17. Midbrain Highest portion of the brain stem
Involved in controlling ________________ movement and _______________ size

18. _______________________
Relay center for incoming messages
Kind of like the
Pony Express,
:~)

19. Hypothalamus Controls various body processes
_________________
__________________
Through the __________________gland it controls metabolism, sexual development, and emotion

20. Peripheral Nervous System (PNS)
Nerves outside of the ______________________________________
Sends info from inside and outside of your body to the CNS for the brain to respond to

21. PNS Parts A__________________ Nervous System

22. Autonomic Nervous System
Controls Involuntary functions
_______________________—Reflex—”Fight or Flight”
_______________________—opposes actions of the sympathetic nervous system by slowing bodily functions during rest

23. Somatic Nervous System
Relays messages from the eyes, ears, nose, tongue, and skin to the CNS which sends a response to the _______________________ muscles to move or react to a situation

24. Neurons
Nerve cells
Cell body -__________________________________________________________________________________—nucleus
_______________—branched structures that extend from the cell body. They receive info from other neurons or sensory receptors and transmit impulses toward the cell body
_______________—transmit messages away from the cell body and toward other neurons, cells, or glands
