A neuron in vertebrates generally humans consist of four major regions.
1. A cell body - is the enlarged portion of the neuron and is covered by a cell membrane. It contains the nucleus and the mitochondria and other organelles.
2. Dendrite - are thin cytoplasmic extensions of the body that receive information in the cellbody.
2. Axon - are also thin cytoplasmic extension but they carry information away from the cell body.
4. Synaptic terminals - are formed at the ends of those axons which divide and re-divide.

A neuron is consist of nucleus and covered by cell body. The cell body branched out is termed as the dendreon and the longest extension of the dendreon is termed as axon. The dendreons are further branched out are known as dendrites. The axon terminal branched out into synaptic ending or the ending of the axon terminal is termed as the synaptic ending. The axon terminal is covered by a seath like structure is termed as myelin seath. The myelin seath is discontinued at certain places are termed as nodes of ranvier.
