During the second half of an action potential
Weba second action potential is generated until the interval reaches the absolute refractory period When the stimulus voltage is increased, _______. a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

During the second half of an action potential
Did you know?
Web"Second upstrokes," i.e., action potentials arising dur- ing the course of repolarization, were noted by Trautwein early in the course of the study of the cardiac action potential via intracellular recording.16Second upstrokes arise after a brief arrest of repolarization, i.e., during an early afterdepolarization. WebDuring the absolute refractory period no second CAP was recorded because: A) the voltage-gated sodium channels can open, but the shock needs to be bigger to produce action potentials. B) the voltage-gated sodium channels are inactivated, so can not open to produce an action potential.
WebDuring the falling phase of action potential, the membrane repolarizes beyond the resting membrane voltage. This phenomenon is due to? A large number of open potassium channels. More potassium channels are open during the membrane's resting state, allowing more K+ ions to leave the cell. CCI Which two ions travel across the cell membrane … WebSep 26, 2024 · An action potential is a predictable change in membrane potential that occurs due to the open and closing of voltage gated ion …
Weba. once an axon reaches threshold, the amplitude and velocity of an action potential are nearly equal each time b. all neurons produce an action potential at the same time or none at all c. all of the extracellular sodium enters the axon, or none at all d. neurons are either active all the time or not at all a WebThere are three main events that take place during an action potential: A triggering event occurs that depolarizes the cell body. This signal comes from other cells connecting to the neuron, and it causes positively charged ions to flow into the cell body.
WebJan 5, 2024 · The relative refractory period is a period after one action potential is initiated when it is possible to initiate a second action potential, but only with a greater depolarization than was necessary to initiate the first. The relative refractory period can be understood at least in part by the hyperpolarizing afterpotential.
