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 Thanks for your attention • • • • • • https://users.itk.ppke.hu/neurobiologia/LECTURES_20162017_SEMESTER_1/3.%20WEEK/1.%20HANDOUT/Neurob_7.pdf https://users.itk.ppke.hu/neurobiologia/LECTURES_20162017_SEMESTER_1/3.%20WEEK/1.%20HANDOUT/Neurob_8.pdf https://users.itk.ppke.hu/neurobiologia/LECTURES_20162017_SEMESTER_1/3.%20WEEK/1.%20HANDOUT/Neurob_9.pdf https://en.wikipedia.org/wiki/Neuron#cite_note-r1-4 https://en.wikipedia.org/wiki/Nissl_body https://en.wikipedia.org/wiki/Neuroglia
