ActionScript 2.0 :: Draw And Call A Simple Movie Clip?

I am new to actionscripts and I'm having some difficulty. I am creating a website that teaches kids about the about the brain and I am creating a website very familiar to this one,[URL]..So far I only know how to draw and call a simple movie clip such as what you see below. What I am trying to do is create the features that you see on the above website. I'll try to explain as best as possible what I have done so far:

I created one flash file and drew the background for where the text will display. Next I created several movie clips for each of the brain parts and I placed an invisible button over each of these movies. For example I told the button, "cerebellum_button" to play the movie "cerebellum_mc" and told it to go to the "turnon" label." Once it stopped at the label "turnoff" it displayed the text for what the cerebellum does.

I don't think that the below method is efficient, I feel that my code is redundant because I�m having to create a button for each animated movie clip, then each one of those movie clips displays text. It seems to me that I can somehow create a text in a centralized location and call it. However because I am new at this stuff I have had to create text in each of the movie clips. Is there a way that I can centralize all of the text then call it? My aim is to have the user roll over the brain part, have it animate, and have it display the text to explain what that brain part does. So far this is what I have working, I have one button and one animated movie that includes text.

cerebellum_button.onRollOver = function(){
cerebellum_mc.gotoAndStop("turnon");
}
cerebellum_button.onRollOut = function(){
cerebellum_mc.gotoAndStop("turnoff");
