1. THE NERVOUS SYSTEM
THE NERVE CELL (NEURONS)

2. THE NERVE CELL

3. • MOTIVATION DRILL/GAME: PASS THE MESSAGE
THE CLASS WILL FORM A 2 GROUP, EACH
GROUP HAS 6 MEMBERS.
• THE FIRST MEMBER WILL RECEIVE THE MESSAGE
AND PASS IT TO THE OTHER MEMBERS THROUGH
WHISPERING UNTIL IT REACH THE LAST MEMBER.
THE LAST MEMBER WILL WRITE THE MESSAGE TO
THE BOARD. THE GROUP WITH THE FASTEST TIME
WILL WIN THE GAME AND WILL BE AWARDED.

4. NERVE
CELL
- IT IS THE BASIC UNIT OF THE NERVOUS
SYSTEM
- ALSO KNOWN AS “NEURONS”
- THERE ARE 12-14 BILLIONS OF NEURONS OR
NERVE CELL IN ONE PART OF THE BRAIN ALONE.
A NEURON HAS A CELL BODY CONTAINING THE
NUCLEUS.
DENDRITES AXONS
CELL BODY

IMPULSES OR
SIGNALS TOWARDS
THE CELL BODY

6. • Neurons are cells with the special ability to carry
signal or impulses. The signal or impulse can be
thought, emotions, learning, and many other
body functions are carried by nerve impulse in
the neurons.
• A nerve impulse cannot travel or jump from one
neuron to another. When a nerve impulse comes
to the end of the axon, it produces the chemical
called the neurotransmitter. The neurotransmitter
is a chemical that crosses the space between the
neurons (Synapse) and stimulates the nerve
impulse to start in the next dendrites.

8. -The nervous system is assisted by five sense organs
• eyes, nose, ears, tongue, and skin.
-These sense organs are constantly receiving
information from the environment and sending
messages to the brain. These senses aid in the
survival of human beings.
- A human must be able to respond to a stimulus in
order to survive.
STIMULUS- is any factor that may trigger a nerve
impulse.
RESPONSE- is a reaction to the stimulus.
