Action Potential in motor NeuronNormal RMP Resting membrane potential of neuron is 70Depolariation Presynaptic membrane haveVoltage sensitive sodium channels whose activation cause and entryof Na sodium inside So when membrane potential reaches 55 mvAction potential fires by opening sodium channels and allow entryof sodium channels inside and Membrane potentialovershoots to 55 mvRepolarisation when depolarisationreaches to 55 mv K channel opens and Na channels becomeinactivated which causes repolarisationHyperpolarisation Unlike Na channels Kchannels are slow hence when action potential reaches restinglevel continuous efflux of K causes more negativity inside cellmembrane leading to See Answer
