The Central Nervous
System

Central Nervous System




There are two main
parts of the central
nervous system.
The brain is the
control center.
The spinal cord is the
main highway.
The nerves (neurons)
are the signal carriers.
The Brain facts



The brain is the
control center of the
body.
The average adult
human brain weighs 3
pounds.
The brain contains
about 100 billion
nerve cells.


Your brain is about
2% of your total body
weight but uses 20%
of your body's energy.
The energy used by
the brain is enough to
light a 25 watt bulb.
Parts of The Brain


The Frontal Lobe is the
primary command and
control center of your
brain. It is responsible for
reasoning and problem
solving. It can also be
involved in motor control
and memory.
The Parietal Lobe helps
to process pain and touch
sensation. It is also
involved in thinking.
Parts of The Brain


The Temporal Lobe
helps to process
sound and language.
It is also involves
emotion, memory and
speech.
The Occipital Lobe
involves vision and
processing.
Parts of The Brain


The Pons help
control automatic
body functions.
The Cerebellum
helps with controlling
movement. It helps to
control posture,
balance, and helps
people to learn
movement.
Parts of The Brain




The Cerebrum is the most
highly developed part of
the human brain.
It is here that things like
imagination, thought,
judgment, and decision
occur.
The Brainstem is the
region of the brain that
connects the cerebrum
with the spinal cord.
Motor and sensory neurons
travel through the
brainstem allowing for the
relay of signals between
the brain and the spinal
cord.
The Spinal Cord



The spinal cord is the
main pathway for
information
connecting the brain
and peripheral
nervous system.
A pair of spinal nerves
leaves each segment
of the spinal cord.
The length of the
spinal cord is about 45
cm in men and 43 cm
in women.
Parts of The Spinal Cord


The Cervical
Nerves are
responsible for
relaying messages
and ensuring
functioning to
different body
parts.
C1-C7 controls the
head, diaphragm,
upper body
muscles, wrist ,
triceps, and hand.



Thoracic spine
refers to the
upper- and
middle-back.
T1-T12 controls
the chest and
abdomen
muscles.
It is built for
stability and
plays an
important role in
holding the body
upright and
providing
protection for
the vital organs
in the chest.
Parts of The Spinal Cord


Lumbar
spine has no
spinal cord
and is made
up of a large
amount of
space for the
nerve roots.
L1-L5 controls
the leg
muscles.


Sacral nerve
is located at
the bottom of
the spine.
S1-S5 control
the bladder,
sex functions
and bowels.
