A study now identifies an interaction between them that controls microtubule organization and thereby protein sorting into axons and dendrites. Once neurons have completed their last cell cycle, they must migr ...

Unit 22.1: The Nervous System
... A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in the sodium-potassium pump to open, allowing ...
