The soma is the cell body of the neuron that contains the nucleus and much of the other 'life' of the neuron. Dendrites and axons reach out from the soma to connect with other neurons.
The cell membrane of the axon and soma contain voltage-gated ion channels that allow the neuron to generate and propagate an electrical signal (an action potential). These signals are generated and propagated by charge-carrying ions including sodium (Na +), potassium (K +), chloride (Cl â), and calcium (Ca 2+).
