Title: PhysioEx 9.0 Exercise 3 answers---I have different questions than yours!?!?
Post by: ladams2 on Oct 8, 2012
I have been looking through all of these posts, but non of these question fit my book/questions. 

For example:  Exercise 3, Activity 1, Questions #1  Explain why the resting membrane potential had the same value in the cell body and in the axon?
   Quetions #2   Describe what would happen to a resting membrane potential if the sodiume-potassium transport pump was blocked.

All of the forums that I have read to get help with this entire Exercise 3 seems different than mine.  Anyone have my type of questions????  I am struggling with this as are my fellow classmates.

The resting membrane potential is the same because the permeability of the ions is the same in both locations.

If the sodium-potassium pump is blocked, sodium will flow in, depolarizing the membrane.

Ok, sorry I feel retarded, but when I open up other forums regarding PhysioEx 9.0 Exercise 3, the questions are different.  Am I missing something or looking at something wrong??

Perhaps a different version? These questions were taken from the pre-lab. The ones you see are probably from the review.
