NERVOUS SYSTEM

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


Central nervous system
Central Nervous System

  • _______________ and ______________

  • Receives messages from the PNS (__________________________________________________________________) and sends a response or reaction.

  • Tells the body how to ______________________________________


_________________

  • About 18 +/- inches

  • Sends messages from __________________________ to ________________________ and visa versa.


Brain
Brain

  • _______________________________________________________________________________________________________________

  • Allows you to think, reason, coordinate, learn, remember, perform all bodily functions whether voluntary or involuntary


Brain parts

Cerebrum
Cerebrum

  • LARGEST, most complex part of brain

  • Controls __________________________________________________________________________

  • ______________side controls the left side of the body

  • ______________ side controls the right side of the body


Cerebrum lobes

Frontal lobe
Frontal Lobe

  • Voluntary ______________

  • Use of _________________

  • _____________

  • _____________


Parietal lobe
Parietal Lobe

  • Sensory Information

    • _____________

    • _____________

    • _____________

    • _____________

    • _____________—where your body is and what it is doing

___________________________

  • Coordinates movement of the skeletal muscles

  • Posture

  • Balance


Brain stem
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


Brain stem parts
Brain Stem Parts

  • _______________________

  • ____________________

  • ____________________

  • Thalamus

  • Hypothalamus


Medulla oblongata
Medulla Oblongata

  • The lowest portion of the brain stem

  • Regulates _____________________ rate

  • Regulates _____________________ rate

  • Regulates hearing, talking, and swallowing

  • Regulates reflexes such as:

    • ______________________

    • ______________________

    • ______________________


Pons

  • Sits just above the M.O.

  • Connects nerve impulses to other parts of the ______________________

  • Helps breathing

  • Controls muscles of the ________________________________


Midbrain
Midbrain

  • Highest portion of the brain stem

  • Involved in controlling ________________ movement and _______________ size


_______________________

  • Relay center for incoming messages

Kind of like the

Pony Express,

:~)


Hypothalamus
Hypothalamus

  • Controls various body processes

    • _________________

    • __________________

    • __________________

  • Through the __________________gland it controls metabolism, sexual development, and emotion


  • Peripheral nervous system pns
    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


    Pns parts
    PNS Parts

    • A__________________ Nervous System

    • ____________________ Nervous System


    Autonomic nervous system
    Autonomic Nervous System

    • Controls Involuntary functions

      • _______________________—Reflex—”Fight or Flight”

      • _______________________—opposes actions of the sympathetic nervous system by slowing bodily functions during rest


    Somatic nervous system
    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


    Neurons
    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
