in which glossary would you expect to find a listing for the critical vocabulary words that are highlighted in each section

A glossary is a dictionary of terms specific to a certain subject. A biology textbook might have a glossary in the back, so you can quickly look up all those technical words. A glossary can also come at the end of a chapter or even in footnotes. The glossary is often found at the end of a book or article and is usually in alphabetical order.
