Action Potential - The Definitive Guide Biology Dictionary

WebThe ability to generate graded potentials The ability to have a refractory period in which the cell is insensitive to stimulation The ability to create a relatively stable resting membrane voltage The ability to propagate multiple signals of varying strength and magnitude along the axon The ability to generate action potentials. WebPropagation of an action potential through the T-tubules into the sarcoplasmic reticulum triggers the release of Ca++ into the cytoplasm of a skeletal muscle fiber. The motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. how to maintain battery https://1stdivine.com

Action Potential and How Neurons Fire - Verywell Mind

WebA recently depolarized area of a cell membrane cannot generate an action potential because of the absolute refractory period On a typical neuron, the axon is usually longer in length than the dendrites. true On a graph of an action potential, the small depolarizations that lead to threshold are from excitatory postsynaptic potentials (EPSPs).
