Need to edit product page tab headers - can't find them!

[solarshell]

I'm fairly new to Joomla and while I've been able to hunt down other part of the the site, the page tab headers are a complete mystery to me. Can you help me figure out where they are?

Where can I edit those tab headers: Description, View More Images, Cusotmer Reivews? Seems so simple - product page/tabs/edit but they are no where to be found.
