Universidad ue Europea Action potential in neurons Dendrites Neurons (nerve cells) are the core components of the nervous system. They provide critical functions such as control ling muscle activity, sensing thinking, remembering, and regulating glandular secretions. Soma Electrical signals and chemical messengers are used to transmit and receive information between them. The neurons consist of: Nclen Asos The cell body (soma) and its processes Dendrites: the branched projections of a neuron that act to propagate the electrochemical stimulation received from...
