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 _____________ 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

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 ____________________ 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
