Are there shortcodes or php include-type options for showing product description, reviews, etc.

[Penrose]

Details: On my products page I have tabs that are generated by Custom Fields. In the same UL (tabs) I want to have Description and Reviews but right now I don't know how to incorporate those two sections. I want each tab to show the default product description and reviews section automatically. 

Question: In the front-end are there shortcodes or options that I can use inside Custom Fields that will call/show the product description and reviews? And in the back-end are there PHP include-type options?
