Answer 1

☆$\red {HELLO\:DEAR}$☆

• A neuron consists of a cell body witha 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.

Answer 2

Answer:

Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. It is primarily the surfaces of the dendrites that receive chemical messages from other neurons
