Definitions and functions and its
parts. (Celinda)
• The nervous system is
one of the major
regulatory systems of the
body maintaining
homeostasis. Its functions
are, monitoring the body’s
internal and external
environments. Another
function: integrate
sensory information. And,
direct or coordinate the
responses of other organ
systems to the sensory
input.
Vocabularies• Central Nervous system
• Peripheral Nervous
system
• Brain
• Spinal Cord
• Nerves
• Neurons
Definitions continues….
• Central Nervous System- consists of brain and
spinal cord
• Peripheral Nervous System- consists of sensory
organs, such as eyes, ears, and body nerves
• Spinal Cord- cord of nerve tissue in the spinal
column
• Nerves- cord like fiber carrying impulses to and
from the brain.
• Neurologic- medical that deals with the nervous
system and disorders affecting it.
Disorders and Diseases of the
Nervous System (Rachel)
• Most of the diseases and
disorders of the Nervous
System are located in the brain
itself and its surrounding
structures. Some other
diseases lead to closure of
some of the blood vessels of
the brain. A spinal cord
disease associated with injury
or compression of the spinal
nerves. A disorder is the
pressure inside or around the
skull. It also involves the blood
flow to the brain. If brain cells
die, it causes a brain attack or
stroke.

Examples of Disorders and
Diseases
Diseases
1)
2)
3)
Multiple Sclerosis- This is a disease
of the central nervous system that is
an unpredictable condition that can
be relatively benign, disabling or
devastating, leaving the patient
unable to speak, walk, or write.
Spine Disease- associated with
injury or compression of the spinal
cord or spinal nerves.
Brain Tumor- an abnormal growth
that involves the brain itself or its
surroundings structures. Two
general classes: 1. Intra- axial
tumors- tumors which grow with in
the substance of the brain. 2. Extraaxial tumors- tumors that originate
outside of the actual tissues of the
brain, but can involve the brain
because of their close proximity.
Disorders
1)
2)
Brain attack (stroke)- Happens
when brain cells die because of
inadequate blood flow to the
brain
Intracranial pressure (ICP)- The
pressure inside the skull.
Definition continues…
• Inadequate- Not enough or not good enough
• Symptom- setting that shows that you have
on illness
• Tumors- an abnormal lump or mass of tissue
in the body
• Seizures- a sudden attack of illness or a
spasm
• Epilepsy- a disease of the brain that causes a
person to have sudden black outs or
convulsions.
Identify the Major parts included in
your systems ( Melissa)
• The two major parts
of the nervous system
is the central nervous
system and peripheral
nervous system. The
central system
controls your body or
the spinal cord. The
peripheral nervous
system connects to
your organ.
VocabulariesCentral nervous system- brain
Peripheral nervous system- vein
The important of your system
and why it is vital to your
body’s Survival (Jennifer)
• Brain is important because it helps us
think, feel, remember, and imagine. The
brain keeps the body in order. Without
your brain, we can’t do anything. Brain
helps us control our body. It helps us keep
working.
