A neuron is the basic unit of the nervous system, which includes the cell body, dendrites, and an axon. The axon is a long, slender projection that conducts electrical impulses away from the neuron's cell body. The terminal bud (also known as the synaptic terminal, terminal bouton, or synaptic end bulb) is found at the end of the axon and is responsible for transmitting the signal to other neurons or muscles. Therefore, in terms of size, the neuron (including all its parts) is larger than the axon, which in turn is larger than the terminal bud.
