2. NERVOUS SYSTEM
is a complex
collection
of nerves and
specialized
cells known as
neurons that
transmit
signals between
different parts
of the body.

3. FUNCTION OF THE NERVOUS
SYSTEM
• Governs all your conscious activities
like:
LEARNING THINKING

4. FUNCTION OF THE NERVOUS
SYSTEM
• Controls the involuntary functions of
some organs like:
BREATHING HEARTHBEAT

5. FUNCTION OF THE NERVOUS
SYSTEM
• Responsible for your emotions such:
FEAR LOVE ANGER

6. TWO TYPES OF THE NERVOUS
SYSTEM
PERIPHERAL CENTRAL
the nervous
system outside the
brain and spinal
cord
the complex of nerve
tissues that controls the
activities of the body

7. AUTONOMIC
NERVOUS SYSTEM
TWO TYPES OF
PERIPHERAL NERVOUS
SYSTEM
controls the nerves of
the inner organs of
the body on which
humans have no
conscious control.
This includes the
heartbeat, digestion,
breathing (except
conscious breathing)
etc.

8. SOMATIC NERVOUS
SYSTEM
consists of peripheral
nerve fibers that pick
up sensory
information or
sensations from the
peripheral or distant
organs (those away
from the brain like
limbs) and carry
them to the central
nervous system
TWO TYPES OF
PERIPHERAL NERVOUS
SYSTEM

9. BRAIN
TWO TYPES OF CENTRAL
NERVOUS SYSTEM
The brain lies within the
skull and is shaped like
a mushroom. The brain
weighs approximately
1.3 to 1.4 kg. It has
nerve cells called the
neurons and
supporting cells called
the glia.

10. SPINAL CORD
TWO TYPES OF CENTRAL
NERVOUS SYSTEM
The spinal
cord is along
tube like
structure
which extends
from the brain.
The spinal
cord is
composed of
a series of 31
segments.

11. OTHER PARTS
OF THE CENTRAL
NERVOUS SYSTEM

12. NEURON OR
NERVE CELL
NEURON
a cell that carries
messages
between the
brain and other
parts of the
body and that is
the basic unit of
James Chadwick

13. CELL BODY OF
A NEURON
STRUCTURE OF A
NEURON
like any other
cell with a
nucleus or
control center
MATTHIAS SCHLEIDEN

14. AXON
is a long, slender
projection of the
nerve cell
that carries
impulses away
from the cell
body.

STRUCTURE OF A
NEURON

15. DENDRITES
any of the
usually
branched
fibers that
carry nerve
impulses
toward a nerve
cell body
