I. process of initiating nerve impulse
WebJan 9, 2014 · Ohio State University researchers have discovered how a key protein finds its way to the right spot on the axon to launch these vital electrical impulses, which enable communication of nerves’ sensory, movement and memory signals to and from the brain. Image courtesy of Chen Gu, Ohio State University WebAug 7, 2011 · 1. Initiation or Generation of a Nerve Impulse (Action Potential) At rest, the voltage-sensitive sodium and potassium gates in the channels in the plasma membrane of a nerve cell are nearly closed and the Na+/K+ pump moves 3 Na+ ions to the ECF and 2 K+ ions to the ICF. This contributes to the formation of a resting membrane potential of -70 ...
