What is ventricle depolarization?
Type your answer here... abnormally slow depolarization of the ventricles would most change the shape of the ?in an ekg tracing
What change in membrane potential triggers action potential?
depolarization
Define the term depolarization?
Depolarization is a term used in biology. It is the change in or loss of polarity or polarization in a cell by removing some of the negative charges.
What change in membrane potential depolarization or hyperpolarization triggers an action potential?
despolarization
What is depolorization?
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
What change in membrane potential triggers an action potential?
An ion channel.
When threshold is reached depolarization occurs with the same amplitude of potential change This is known as?
the all or none law
As heart ventricles contract and then relax blood pressure inside of arteries change from?
systolic to diastolic
What can CMD do?
man cmd csan do many things like change pass without knowing it and tracing website . getting anyones ip tracing mails ,internet personal info .. and lots of stuff
What change in polarization is the t waves on an ecg tracing?
t wave just appears before the ventricular relaxation
How do you change sizes on your penguin on Club Penguin?
It is impossible to change sizes unless you hack, which is illegal. If you see a non computer controlled penguin with a abnormally sized penguins report them immediately.
What does it mean when a graded potential is called graded Why does it get this name?
Greded Is the membrane voltage change in response to a change in membrane permeability by adding or taking out gate channel. Depolarization occurs when there is a change in voltage towards a positive values b/c of opening up Na+ gate channels Hyperpolarization occurs when there is a more negative change in voltage due to opening up Cl- or K+ gate channels. It is called "graded" b/c you can open up some or many channels so the depolarization or hyperpolarization can be big or small Graded potentials start in one spot b/c of a change in permeability and then spreads to others as it travels; called local circuit current. The strength of graded potentials decreases as it spreads along the axon and eventually dies If you inject negative ions into the cell a hyperpolarization occurs If you inject positive ions into the cell a depolarization occurs If you inject a lot of positive charge the membrane depolarizes past 0 creates action potential and then comes back down' You get action potential once you pass the threshold voltage potential. Is a rapid depolarization which repolarizes
