When the chemically gated ion channels open which ion is mainly responsible for depolarizing the sarcolemma?
The main ion responsible for depolarizing the sarcolemma is sodium (Na+).
What is the purpose of a depolarizing agent in a battery?
The term depolarizing agent has been used to denote a substance used in a primary cell to prevent buildup of hydrogen gas bubbles.A battery depolarizing agent takes up electrons during discharge of the cell; therefore, it is always an oxidizing agent.
Does Valium depolarize or hyperpolarize a cell?
Yes it has a depolarizing effect.
What does eshmeron mean?
It is a non-depolarizing muscle relaxant, apparently.
What is the period when the atria are depolarizing?
atrial diastole
What is the difference between depolarizing and non-depolarizing drugs?
nondepolarizing meds act as an antagonist to acetylcholine at the myoneural junction in the muscle. Polarizing will mimick the effects of acetylcholine and cause membrane depolarization at the neuromuscular junction. In other words, look over your action potential.
The period during which the ventricles are depolarizing which precedes their contraction?
QRS wave
When acetylcholine receptors open which ion is mainly responsible for depolarizing the sarcolemma?
sodium
Depolarizing muscle relaxant used in surgery?
I believe you're thinking of succinylcholine.
What principle states that the properties of the action potential are independent of the relative strength of the depolarizing stimulus?
the all-or-none principle
The start of an action potential?
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
How is an action potential self-regenerating?
depolarizing currents established by the influx of Na+ flow down the axon and trigger an action potential at the next segment
