Quizplus · Accepted Answer

The soma, or cell body, contains the nucleus and organelles necessary for the majority of a neuron's functions, including metabolism, maintenance, control, and performance. While dendrites receive signals and axon terminals release them, these processes are supported by the soma's metabolic processes. Vesicles function in the transport and release of neurotransmitters, but they do not contribute significantly to the neuron's basic metabolism and maintenance.
