Question

You place two nerve cells which have synaptic connection to each other and are normally able to signal to each other in a dish filled with a buffer containing H Na and Cl as the only inorganic ions You stimulate the first neuron by applying a depolarizing voltage across the membrane of one of the dendrites but find that the second neuron does not respond Which of the following is the most likely explanation for its lack of response a An action potential can only be initiated by opening a ligand gated channel b Propagation of the action potential along the axon is prevented by the lack of K in the buffer c The axon membrane is unable to repolarize i this buffer d Neurotransmitter is not being released into the synaptic cleft e Neurotransmitter is released but is unable to stimulate opening of the ligand
