Hey jan, what textbook are you using for this?

Martini, Frederic H. and Nath, Judi L. "Fundamentals of Anatomy & Physiology" 8th Edition

I think we have access to that test bank. I'll get back to you if I fid the answers

Thanks!

Hey janjane, believe it or not, there is no test bank for this book, or none that I could find for both the 8, 9 and 10th edition.

Someone correct me if I'm wrong.

But, on the bright side, some of these questions are quite easy! I would go through them, but there are so many. Pick out the ones you're absolutely unsure of.

is there any older edition? :thi:

My apologies, there is a test bank for this book :-:) but I'm not allowed to publish the questions. It's copyright material :-\. However, I can still help you with the questions.

That fine! :) Thanks for the help.

Question?  [?-?] how can i access the test bank section?

You have to have greater than 25 posts

oh wow, i guess i have to work on my numbers. :thi:

the send message doesnt work. ???

Same reason as before JanJane...

okay thanks!

Hey Jan i need help also:  my questions are same but different.

here are some websites to find the answers

for example the answer to the False question of cytoplasm is = includes cytosol, this is the answer
 sorry i cant post a link were i found the help
