Question

Quizplus · Accepted Answer

When an impulse (or signal) enters a neuron, it is received by the dendrite and then passed on to the next cell (either another neuron or an effector cell) via the axon. The soma (or cell body) contains the nucleus and other organelles, but it does not play a direct role in transmitting signals. Therefore, choices C, D, and E can be eliminated. B is the opposite of the correct sequence, so A is the best choice.
