Unique features of neurons, which distinguish them from other somatic cells By Balogh Olivér

Structure having specialized projections that are used for networking and communication axon and dendrites supported by special cells and complex mesh of structural proteins Glial cells and neurofilaments well developed rough endoplasmatic reticulum system units can be found Nissl bodies

Function the nervous tissue (neurons + glial cells) is responsible for processing the incoming information from the environment also to regulate the basic functions of the body neurons are highly excitable, maintaining a -70mV resting potential they communicate by neurotransmission (chemical and electrical synapses)

Life cycle most of the neurons are incapable of self-division and are persist without replacement though studies showed that (in the human brain) for a minority of cells the neurogenesis is possible also possible for the axons to regrow if they are severed
