brain stem controls involuntary functions
central nervous system made of the brain and spinal cord
cerebellum coordinates voluntary muscle movement and regulates balance
and posture
cerebrum controls memory, language, and thought
nervous system gathers, processes, and responds to information neuron
basic functioning unit of
the nervous system
peripheral nervous system sensory and motor neurons that transmit
information between the central
nervous system and the rest of the body physical relating to material things
reflex automatic movement in response to a stimulus
spinal cord tube like structure of neurons
stimulus change in an organism’s environment that causes a response
synapse gap between two neurons
NERVOUS SYSTEM

smelling seeing, hearing,
Tasting,_______,
Dreaming
thinking,___________,
breathing, heart
beating, moving, running, sleeping,__________,
laughing
singing, remembering, feeling pain or pleasure,
painting, writing...you couldn't do any of these
things without your central nervous system!
WHAT IS THE NERVOUS SYSTEM?
brain
cord
Made up of your________,
your spinal_______,
and ________that
thread throughout your body.
nerves
control
 It's the _________center
for your entire body.


Your brain uses information it receives from your
nerves to coordinate all of your actions and
reactions. Without it, you couldn't exist!
WHAT ARE NERVES?

thin
They're the _____threads
of nerve cells, called
__________that
run throughout your body.
neurons

they carry messages back and forth just the way that
telephone wires do.
send
__________nerves
______messages
____the
brain
Sensory
to
and generally connect to the brain through the
spinal cord inside your backbone.
 ________nerves
carry messages ______the
brain
Motor
from
to all the muscles and glands in your body.

SO HOW DO THEY PASS ALONG MESSAGES?

__________are
thin. Some are very small, and
Neurons
some can be three feet long! All are shaped
stars
somewhat like flat ________which
have long
fingers. The fingers of one neuron almost reach to
the next neuron, to ______on
information.
pass
REMIND YOU OF ANYTHING?

How about a cool relay of dominoes in
which one standing domino falls and
trips the next and the next and the next.
DURING A FOOTBALL GAME, THE COACHES
STAND ON THE PERIPHERY OF THE FIELD.
prefix peri- means "around or outside."
 What does periphery mean in the statement on
the board?



The coaches stand outside the boundary of the field.
What do you think the peripheral nervous system
is?

it is part of the nervous system outside of something. It
is the part of the nervous system that is outside the
central nervous system.


Your Nervous System consists of all of the
following, except…..
 A.
Brain
 B. Heart
 C. Spinal Cord
 D. Nerves
DISCUSSION QUESTIONS

What are some of the tasks performed by the
nervous system?
 The
nervous system gathers information, reacts to
changes in the environment, and makes
adjustments that maintain homeostasis—the
regulation of their internal environment.
DISCUSSION QUESTIONS

What are the two parts of the central nervous
system?
 the
brain and the spinal cord
REFER TO BOOK

How do the PNS and the CNS interact?
 The
PNS is made of neurons that transmit
information between the CNS and the rest of the
body.
DISCUSSION QUESTIONS

How does a reflex work?


Responding nerve signals are sent directly from the
spinal cord to the appropriate muscles.
Give an example of how the nervous system works
with another body system to maintain
homeostasis?

One example is shivering when cold. The nervous
system senses changes in temperature around the
body and signals the muscular system to contract. The
shivering action creates movement to warm up the
body.
