What does a neuron look like?

उत्तर
- A neuron consists of a cell body with a nucleus and cytoplasm. It has two important extensions known as the axon and dendrites.
- An axon is a long, thread-like extension of nerve cells that transmits impulses away from the cell body. Dendrites, on the other hand, are thread-like extensions of cell body that receive nerve impulses.
- Thus, the axon transmits impulses away from the cell body, whereas the dendrite receives nerve impulses. This coordinated function helps in transmitting impulses very quickly.
