Question

A voltage across the membrane of an unstimulated neuron is called the 1 and has a measured 2 voltage If the neuron is stimulated, the measured voltage can3 to the 4 This causes to rapidly open and close, which results in a series of cellular events that generate an 6 . The first event is the of 8 , resulting in the of-?10. This leads to 11 of the membrane. Next the12 and the 13 resulting in the 14 of 15 This leads to 16 of the membrane. Finally, the 17 and there is a brief 18 when the neuron cannot be restimulated
