Impulse goes down through the T tubular after the calcium is released it causes the release of the troponin and then the myosin to attach When sodium enters that is depolarization Enzyme that breaks the acetylcholine called: acetylcholinesterase -ase=enzyme Pg. 288 something in bold: refractory period: lost excitability Refractory period: When something depolarizes and then the process of depolarization to depolarize again.
