The Intricacies of the Nervous System
The Nervous System
By: Sonia Espinosa, Matt Marchisotta, and Jillian
Abizadeh
The Nervous System’s Main Function
Your body’s control system, it sends, receives, and processes nerve
impulses all throughout the body
The nervous system is comprised of nerves made up of specialized cells
known as neurons
The nervous system is essential when it comes to perceiving and
comprehending the external world
Where is the nervous system in your
body?...everywhere!
Main parts of the System and vocabulary
Brain- An organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation
and intellectual and nervous activity
Cerebrum- The principal and most anterior part of the brain in vertebrates
Cerebellum- The part of the brain at the back of the skull in vertebrates, it also coordinates and regulates muscular activity
Medulla- The inner region of an organ or tissue, especially when it is distinguishable from the outer region or cortex
Spinal Cord- The cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all
parts of the body to the brain
Nerves- A whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from
these to the muscles and organs
Neurons- A specialized cell transmitting nerve impulses
Impulses- A sudden strong and unreflective urge or desire to act
Neurotransmitter- A chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by
diffusing across the synapse or junction
Reflexes- An action that is performed as a response to a stimulus and without conscious thought
Stimulus- a thing or event that evokes a specific functional reaction in an organ or tissue
Response- an behavior of a living organism that results from an external or internal stimulus
Some pictures to brighten your day!
….and more!
What each part does:
Central nervous system- consists of the brain and spinal cord, sends out
nerve impulses and analyzes information from the sense organs, it is the
main control center in your body, and the center of thought.
Peripheral nervous system- includes the craniospinal nerves that branch off
from the brain and spinal cord; from the central nervous system, it carries
nerve impulses to the muscles and glands
Autonomic nervous system- regulates involuntary action, such as a heart
beat and digestion.
Never seen a brain?! Well now ya have!
Describe the path a nerve impulse travels
throughout the body from stimulus to response
They pass through the thoracic region to innervate the internal organs
How the system affects other body systems
Receptors in muscles provide the brain with information about body
position and movement. The brain controls the contraction of skeletal
muscle. The nervous system regulates the speed at which food moves
through the digestive tract.
How other body systems affect the system
Bones from the skeletal system provide calcium that is essential for the
proper functioning of the nervous system.
In the endocrine system, reproductive hormones affect the development of
the nervous system.
The digestive system sends sensory information to the brain.
Reproductive hormones from the reproductive system affect brain
development and sexual behavior.
Two diseases of the nervous system
Epilepsy, in which abnormal electrical discharges from brain cells can seize
which means they can cause seizures, epilepsy is triggered by bright and or
flashing lights. That is why there are caution signs in movies or television
shows that have bright and or flashing lights
Huntington’s disease, which is an inherited condition that causes the nerve
cells in the brain to degenerate.
Effects of outside/environmental factors on the
system
Lead in the nervous system causes…
Kidney damage
Learning disabilities
Attention deficit disorder
Decreased intelligence
Fun Facts!
There are millions of nerve cells in the human body. This number even
exceeds the number of stars in the Milky Way.
The human brain consists of about 100 billion neurons. If all these neurons
were to be lined up, it would form a 600 mile long line.
In humans, the right side of the brain controls the left side of the body,
while the left side of the brain controls the right side.
