WebJan 1, 2014 · Action potential (AP) backpropagation, as opposed to forward propagation along the axon, consists of the active conduction along the neuronal dendrites of the depolarization produced by the initiation of an axonal AP. The amplitude of the depolarization generally decreases along the dendrites with increasing distance from the …
WebAction Potential A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. If the threshold of excitation is reached, all Na + channels open and the membrane depolarizes. At the peak action potential, K + channels open and K + begins to leave the cell. ladies leather walking boots size 6WebIn nervous system: Localized potential …reaches what is called the threshold potential, it triggers the nerve impulse, or action potential see below.
