37. FUNCTIONS OF THE NERVOUS SYSTEM
Sensory Input: The nervous system gathers information
from our senses (sight, sound, touch, taste, and smell)
and sends it to the brain.
Integration: The brain processes this information and
makes decisions about what to do.
Motor Output: The brain sends signals to muscles and
glands to make the body respond, like moving your hand
away from something hot or releasing hormones.

38. Neurons are the main cells in the nervous system. They carry
messages throughout the body.
Each neuron has:
DENDRITES: THEY RECEIVE MESSAGES FROM OTHER NEURONS.
AXON: IT SENDS MESSAGES TO OTHER NEURONS OR BODY PARTS.
SYNAPSE: THIS IS THE TINY GAP BETWEEN NEURONS WHERE MESSAGES ARE
PASSED.
NEURONS

39. Glial cells aka helper cells, play a crucial role in
supporting and safeguarding neurons. They
supply nutrients, eliminate waste, and assist in
maintaining the proper functioning of neurons.
GLIAL CELLS

40. The nervous system plays a vital role in all our actions. It enables us to engage
with the world, maintains the function of our organs, and facilitates learning and
memory processes. Exploring its functions can lead to improved health and overall
well-being.
