The phases of the action potential include
WebbThe beginning of the action potential is represented in Figure 1 as phase 1. At this point, the cell is at rest and the membrane potential is approximately -70 mV.During phase 2, … The cardiac action potential differs from the neuronal action potential by having an extended plateau, in which the membrane is held at a high voltage for a few hundred milliseconds prior to being repolarized by the potassium current as usual. This plateau is due to the action of slower calcium channels opening and holding the membrane voltage near their equilibrium potential even after the s…

WebbChronic exposure to the mycotoxin deoxynivalenol (DON) from grain-based food and feed affects human and animal health. Known consequences include entereopathogenic and immunotoxic defects; however, the neurotoxic potential of DON has only come into focus more recently due to the observation of behavioural disorders in exposed farm animals. … WebbOthers are inhibitory, causing the membrane of the next cell to hyperpolarize, thus decreasing the probability of that the next neuron will fire an action potential. The process by which this information is communicated is called synaptic transmission and can be broken down into four steps. First, the neurotransmitter must be synthesized and ...
