Neuron, illustration - Bildbanksillustration

Computer artwork of a neuron. Neurons are responsible for passing information around the central nervous system (CNS) and from the CNS to the rest of the body. Each nerve cell comprises a body surrounded by numerous extensions called dendrites (pink). Dendrites collect information from other nerve cells or from sensory cells. Shown are the nerve cell with the protective myelin (protein that coats and insulates the axons of the nerve cells) sheath in yellow.
