Nervous System:
The nervous system is like the control center of our bodies. It's
made up of special tissues called nervous tissue. The worker in
this system is the nerve cell or neuron. The nervous system is
mainly in charge of managing and coordinating things in complex
animals.
Functions of the nervous system:
1. The nervous system gets information from the world around us.
2. It collects information from different parts of our body.
3. It helps us make decisions and control our muscles and glands.
Neuron or Nerve cell: Neuron is a highly specialized
cell which is responsible for the transmission of
nerve impulses.

The cell body, or cyton, is the main rounded part of the neuron
where you find the central nucleus and cytoplasm.
Dendrites are like the tree branches of the neuron's cell body.
They receive and pass on signals or messages.
The axon is the neuron's long part that carries messages away
from the cell body. It's protected by a covering called the
myelin sheath.
Nerve endings are like tiny branches at the ends of neurons,
and they send electrical signals to other neurons.

E.M.A
Working of a neuron:
1. The neuron gets information from receptors as an electrical
signal at the start of its dendrite.
2. This signal travels from the dendrite to the cell body and then
all the way to the tip of the axon.
3. Between two neurons, there's a small gap known as a synapse.
Special chemicals bridge this gap to transmit the same signal to
the next neuron.
4. At the end of the axon, electrical signals trigger the release of
these chemicals.
A synapse is where the end branches of one neuron's axon
connect with the dendrite of another neuron.
E.M.A
Transmission of nerve impulse: Nerve impulses travel
in the following manner from one neutron to the next.
Dendrites → cell body → axon → nerve endings at the tip of axon → synapse → dendrite of next neuron.
The chemicals released from the tip of a neuron's axon traverse the
synapse or neuromuscular junction to connect with the adjacent cell.
