Action Potential: Definition & Steps - Study.com
WebA receptor potential, also known as a generator potential, [1] a type of graded potential, is the transmembrane potential difference produced by activation of a sensory receptor. [2] A receptor potential is often produced by sensory transduction. [3] It is generally a depolarizing event resulting from inward current flow. WebMar 5, 2024 · Action Potential. A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium ions to … tfiledb.findchrbyaccount
