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

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

___________________________
  • 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
slide18
_______________________
  • 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
