Adjusting and setting points of x and y values

Hi all

I need to make a little diagram - where there are 5 menu items (ie heart, lungs, etc), and a second mc above it, which is an image of a body.

When one of the menu items is clicked, the body mc physically moves under a mask to around the selected area (heart etc), and comes to a smooth stop, no matter where it came from.

So I guess somehow these points are set.

It’s pretty simple but I couldn’t locate any examples.

Anyone know of any tutorials that might be able to help?
