Nervous System By: Sean Moran, Zach Persechino & Shannon

Slide 3
The nervous system is made up of the brain, spinal cord, and a
network of neurons. This system is responsible for sending,
receiving, and interpreting information from all parts of the body.
This system can be divided into two parts: the central nervous
system and the peripheral nervous system.
Slide 4
The central nervous system is the processing center for the
nervous system. It receives information and sends information to
the peripheral nervous system. The two main organs of the central
nervous system are the brain and spinal cord. The brain processes
sensory information sent from the spinal cord. Both the brain and
spinal cord are protected by three layers of tissue called the
meninges. The peripheral nervous system carries information to and
from the central nervous system. There are two types of cells in
the peripheral nervous system. These cells carry information to and
from the central nervous system. Cells of the sensory nervous
system send information to the central nervous system from internal
organs.
Slide 5
Each neuron receives an impulse and must pass it on to the next
neuron and make sure the correct impulse continues on its path.
Through a chain of chemical events, the dendrites pick up an
impulse through the axon and transmitted to the next neuron. The
entire impulse passes through a neuron in about seven milliseconds
faster than a lightning strike.
Slide 6
There are more nerve cells in the human brain than there are
stars in the Milky Way. The left side of human brain controls the
right side of the body and the right side of the brain controls the
left side of the body. An average adult male brain weighs about
1375 grams. An average adult female brain is about 1275 grams.
Slide 7
The Nervous System works with many other systems in your body
they include: Skeletal System because the bones provide calcium
that is essential for the function of the nervous system
Respiratory System because the brain monitors respiratory volume
and blood. Muscular System because receptors in muscles provide the
brain with info about body positions and movements.
THE END!!!! Now you know more about the nervous system. You
probably know how the nervous system functions and works. We hope
you learned new and interesting things!!
