Explanation:
The cells that carries electrical impulses in our body are known as neurons. They are the basic units of the nervous system. Every neuron is made of an axon and dendrites. Dendrites and Axons are known as the nerve fibres. Axon is the in the posterior and the dendrite is in anterior.
There are more than 100 million neurons in human brain, they are almost ten percent of the total cells in the brain. Glial cell and Astrocytes support the neurons. Neurons are connected with other neurons but they don't touch each other, instead there are tiny gaps known as synapses. These gaps passes the signal from one neuron to the next.
