Immunological 'memory' is due to the persistence of antibodies, and long lived (decades) B and T memory cells. Immune responses are much quicker after second or subsequent exposure to the antigen. Where they can differentiate into plasma 'B' cells or cytotoxic 'T' cells within hours. ...
-occurs when a cell reaches threshold potential and voltage gated NA+ channels open allowing the influx of Na+ into the neuron b. repolarization When a nerve cell membrane changes from positive inside to negative inside, the cell membrane is undergoing repolarization. back to original membrane ...
