Great Discussion from Harvard

Great lesson..so go and visit!

·      Note

Is this a process that requires energy?

What are the affects of drugs upon action potential?

How does myelin affect the speed of action potential?

 
Topic

Number Two

If we follow the path that sodium potassium pumps create a message to flow down the axon..then here are some articles to ponder regarding drugs and sodium potassium pumps

Interesting lab

A learned response to first fyear med discussion board..

 

 

The sodium potassium pump maintains the resting membrane potential (which is polarized, i.e. negative with respect to the outside). The definition of “hyperpolarization” is “even more polarized (i.e. more negative) than RMP”… thus an action potential is depolarization, repolarization, hyperpolarization, then after-hyperpolarization (as the K channels inactivate). I know what you’re basically trying to say (which isn’t what the original guy asked, I think), but you’re using the wrong terminology… hyperpolarization (if you can even call that a state) is transient, the dip under the resting membrane potential after an action potential. Wow, too many parentheses.
