Why can’t nerve impulses travel backwards? Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line.
Is it possible for an action potential to travel backwards?
WebFeb 18, 2024 · Why can’t action potentials travel backwards towards the axon hillock? The refractory period prevents the action potential from travelling backwards. There are two types of refractory periods, the absolute refractory period and the relative refractory period. The absolute refractory period is when the membrane cannot generate another … WebJun 8, 2024 · For an action potential to communicate information to another neuron, it must travel along the axon and reach the axon terminals where it can initiate neurotransmitter … notizen tool für windows
