WebThe ultimate goal of the action potential is to spread along the membrane inducing changes in voltage-gated proteins. This process allows ions to follow their gradients and generate electrical current. In order to understand this spreading phenomenon (commonly referred to as propagation), it is important to understand three concepts: membrane ... WebAnswer A) :- The motion capacity generated on the axon hillock propagates as a wave alongside the axon.The currents flowing inwards at a factor at the axon in the course of an motion capacity unfold out alongside the axon, and depolarize the … WebAug 13, 2024 · The formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. cup of cheer mug
