The structure of a neuron: contains nucleus and organelles; receives nerve impulses and conducts it towards cell body whereas conducts nerve impulses away from the body.

The structure of a Neuron: Soma/cell body contains nucleus and organelles; dendrites receives nerve impulses and conducts it towards cell body whereas axon conducts nerve impulses away from the body.

Explanation:

A neuron is the structural and functional unit of the nervous system. A neuron has three main structural components namely, soma, one axon, and many dendrites.  

Soma is the metabolic center of the neuron and does not participate in conduction of nerve impulse. Many small extensions arise from the soma and are called dendrites. The function of dendrites is to carry the nerve impulse from axon terminals of the presynaptic neuron towards soma.

One large extension of soma is axon that carries the nerve impulse from soma to the axon terminals.
