The soma of a neuron, like that of other cell bodies, contains a nucleus and specialized organelles.The cell body is in charge of carrying genetic information, maintaining the neuron's shape, and supplying energy to drive activity. The nucleus of the neuron is the cell body, also known as soma. If the electrical signals transferred inward towards the soma are large enough, an action potential is generated, and the signal is conveyed along the axon.They receive signals from neighbouring neurons and send electrical stimulation to the neuron's soma or cell body.As seen in the neuron diagram, in most neurons – the dendrites extend outwards from the cell body.These are tree-like extensions at the beginning of the neuron that help to expand the cell body's surface area.
