Neurons are the building blocks of the nervous system. They receive and transmit signals to different parts of the body. This is carried out in both physical and electrical forms. There are several different types of neurons that facilitate the transmission of information. The sensory neurons carry information from the sensory receptor cells present throughout the body to the brain. Whereas, the motor neurons transmit information from the brain to the muscles. The interneurons transmit information between different neurons in the body.

2. NEURON
⮚Neuron or nerve cell is the structural and
fundamental unit of nervous system.
⮚ It is the basic building block of the
nervous system.
⮚Neurons are specialized to transmit
information throughout the body.
⮚These highly specialized nerve cells are
responsible for communicating information
in both chemical & electrical forms.

3. PARTS OF NEUTRON
✔DENDRITES : A nerve cell can have many
dendrites which branch many times, their
surfaces are irregular and covered in dendritic
spines. Dendritic tip of nerve cell sets off a
chemical reaction that creates an electrical
impulse.
✔ CELL BODY(soma): The Electrical impulse
travels from the dendrite to the cell body. It
produces all the proteins for the dendrites
,axons & synaptic terminals

4. ⮚AXONS: At the end of the axon ,
the electrical impulse sets off the
release of chemicals. Axon is the
main conducting unit of the neuron
⮚MYELIN SHEATH: It protects
the nerve fibre .It is the insulation of
the nerve fibre
