A neuron consists of a cell body (perikaryon) and its processes, an axon and one or more dendrites. Neurons function in the initiation and conduction of impulses. They transmit impulses to other neurons or cells by releasing neurotransmitters at synapses.he dendrites receive stimuli from other nerves or from a receptor organ, such as the skin or ear, and transmit them through the neuron to the axon. The axon conducts the impulses to the dendrite of another neuron or to an effector organ that is thereby stimulated to action.
A typical neuron has all the parts that any cell would have, and a few specialized structures that set it apart. The main portion of the cell is called the soma or cell body. It contains the nucleus, which in turn contains the genetic material in the form of chromosomes.Neurons have a large number of extensions called dendrites. They often look likes branches or spikes extending out from the cell body. clump of neuron cell bodies, for example, is called a ganglion (plural: ganglia) or a nucleus (plural: nuclei). A fiber made up of many axons is called a nerve. In the brain and spinal cord, areas that are mostly axons are called white matter, and it is possible to differentiate pathways or tracts of these axons.
