Question

Quizplus · Accepted Answer

The long stem that protrudes from a cell body at one end and ends in numerous small filaments at its opposite end is called an axon. Dendrites also protrude from the cell body, but they have shorter and more numerous branches called dendritic spines, which receive input from other neurons. Synapses are the points of communication between neurons where neurotransmitters are released, and vesicles are small structures within neurons that store and release neurotransmitters.
