The brain as we know is the master organ of the body. It controls almost all
bodily functions even if we are awake or not. Our body responds to the
environment automatically and these responses are needed in order for us
to survive. Class, our topic for today is about the Nervous System.

D. Skills:
1. Describing the
structure and
functions of the NS.
2. Illustrating the
work of the CNS and
PNS.
3. Correlating NS to
other body systems.
B. Presentation
1. Give the general functions of the nervous system.
2. Present the major divisions of the Nervous system
and their functions.
3. Based from the presentation of the major divisions
of the NS, let the students fill out the diagram below.
1. It receives information about the environment outside and inside the body.
2. It interprets information gathered.
3. It makes the body respond or react to the information.
•main processing center for the entire nervous system.
•Includes the 1.) brain and the 2.) spinal cord.
•Brain is consist of the Brain stem, cerebellum and cerebrum.
Central NS
•connects the CNS to the organs and limbs.
•a. Somatic NS- associated with the voluntary control of the body movements.
•Could be a sensoy or motor neuron
•b. Autonomic NS-associated with the involuntary control of the body
movements.
•b.1. Sympathetic - activated when the body is in a dynamic role or stress. Ex.:
increased heart rate and breathing, dilation of pupil etc.)
•b.2. Parasympathetic- maintains body functions and restores the body to
normal or relaxed mode.
Peripheral NS

4. Post a picture of a Neuron and its major parts.

5. Describe the Neuron and its parts based on
function.
6. Have the students watch a video presentation of an
action potential by a neuron.

Neuron- carries out impulses or electric signals.
Main Parts:
a. Dendrites- receives stimulation from the body parts
or environment
b. Cell body- composes the cell organelles.
c. Axon- carries impulses away from the cell body. It
is the site of action potential.

7. Tell the class that they will have an activity entitled
“How fast is your Reaction?” and they need to prepare
a ruler and writing materials.
8. Ask the class to find a partner for this activity and
construct on a ½ sheet of pad paper a table of results
just like below.
9. Give the instructions to the students for the activity.
Trials
Centimeters where the ruler fell
Eyes Open Eyes Close
Right Hand Left Hand Right Hand Left Hand

Ave.
a. Have your partner hold a metric ruler at its end with the highest number in cm.
b. Place the thumb and forefinger of your left hand close to, but not touching, the end with the
lowest number.
c. When your partner drops the ruler, try to catch it between your thumb and finger.

10. Process the activity by asking the following
questions:
Q1. Did you catch the ruler faster with your eyes open
or closed?
Q2. Explain why a message moving along nerve
pathways takes time.
Q3. Describe the nerve pathway that the message
followed when you saw the ruler fall.
d. Record where the top of your thumb is, when you catch the ruler. This number gives how many
centimeters the ruler fell.
e. Repeat steps 2 to 5 five more times and record the measurements on the data table that you
have constructed earlier.
f. Repeat steps 2 to 5 five more times using your right hand to catch the ruler.
g. Repeat steps 2 to 5 five more times using your left hand with your eyes closed. Your partner will
signal you by saying “now” when the ruler drops.
h. Repeat steps 2 to 5 five more times using your right hand with your eyes closed. Record your
data and observations.
i. Exchange tasks and drop the ruler for your partner.
j. To complete your data chart, change all the centimeters to seconds by multiplying by 0.01.
k. After recording all the data, compute for the average by adding up the measurements of all the
trials and dividing it by the number of trials
The ruler was caught faster with eyes open.
The message travels from one neuron to another
until it reaches the brain. Then, the brain’s response
is also transmitted by another set of neurons.
First, the eye sees the ruler, and then sends a
message to the brain. The brain sends a response
through the muscles in the hand. Finally, the muscles
contract to allow the person to catch the ruler.

C. Application
1. Introduce the class to an activity entitled: “A Nervous
Trip”
2. Tell the class to form a team of 8-10 members.
3. Present the game set-up of the relay course.
4. Give the guidelines of the game.
-Among the members of the group, assign students who will represent the following parts: Brain,
Organ, Sensory Neurons, and Motor Neurons.
-Have the “Brain” stand at one end of the classroom, and the “Organ” at the other end near the
blackboard.
-Let three to four members representing “Sensory Neurons” stand and line up between the “Brain”
and the “Organ.” Another set of three to four members representing “Motor Neurons” will stand
and line up facing the “Sensory Neurons.”
A. The teacher will show a card to the first member of the group, who is the “Organ.” Each card
will depict a situation of a stimulus affecting an organ.
B. The “Organ” must pass the message to one “Sensory Neuron” by whispering.
Each member who receives the message must relay it to another until it reaches the last “Sensory
Neuron.”
C. Let the last person in the “Sensory Neuron” group run to the “Brain” to communicate the
message that was transmitted from the “Organ.”

5. Process the activity by asking the following
questions:
Q1. How will you differentiate the sensory and motor
neurons based on their functions?
Q2. Based on the simulation activity, explain how
information travels in the nervous system.
D. Generalization
What could be concluded from our topic in the Nervous
System?
D. The “Brain” must think of a reaction to the stimulus presented and pass this response to the
“Motor Neurons.”
E. Each member of the “Motor Neuron” group who receives the response from the brain must
relay it to another until it reaches the last person in the group.
F. The “Organ” will receive this response through the “Motor Neurons” and run quickly to the
board to write the response.
G. The team with the most acceptable answer and the shortest time of trip will win the game
The sensory neurons transmit impulses from the receptor to the brain
while the motor neurons transmit impulses from the brain to the
effector.
Information travels in the nervous system through the neurons that
transmit the impulse. The sense organ receives the message, and
the information is sent by the sensory neurons to the brain. The
brain then processes the information and sends a response through
the motor
neurons to the organ, gland or muscle.
When a receptor such as an organ perceives a stimulus, the impulse is
sent to the brain by the sensory neurons, which then transmit
information from one nerve cell to another. As the message reaches
the brain, it processes the information and commands an effector such
as a muscle or an organ to respond. The message coming from the
brain is sent through the motor neurons.
