Write a note on neurons.
✓
Answer
Neurons are specialized networks of cells that transmit messages from the brain to the body and from the body to the brain. They are the basic units of the nervous system.
A neuron consists of dendrites, axon, cell body, and terminal button or telocentric.
The cell body is the body of neurons. The nucleus of the neuron absorbs the food and keeps the cell alive.
The neural message comes in through the dendrites. These are branch-like structures.
The neural message goes out from the axon of the neuron.
At the end of the axon, there are end buttons. It is a bulb-like structure containing chemicals known as neurotransmitters.
Neurotransmitters are chemical messengers. The neural message jumps across the synapse in order to reach the dendrite of another neuron.
When the neural message is passing through, it excites or inhibits the neurotransmitter in it. This chemical reaction decides our reaction to various situations in life.
