Answer 1

Answer

The structure of neuron: Nerve cells or neurons are the structural and functional units of the nervous system. It consists of three major parts namely, cell body, dendrites, axon.

Cell Body: It is irregular in shape or polyhedral. It contains cytoplasm and certain granular bodies called Nissl's granules which contain a group of ribosomes for protein synthesis.

Dendrites: Dendrites are short fibers that branch repeatedly and protrude out of the cell body. They transmit electrical impulse towards the cyton.

Axon: They are long fibers arising from the cell body with a branched distal end. It terminates in a synaptic knob. It is filled with neurotransmitters.

Answer 2

Answer:

A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. ... The term neurite is used to describe either a dendrite or an axon, particularly when the cell is undifferentiated. Most neurons receive signals via the dendrites and soma and send out signals down the axon.
