Do Buddhists talk about insides?

Buddhists talk about abstract and concrete things, particulars, parts and wholes, etc., and Theravada Buddhism is often I think thought of in terms of an analysis of parts, breaking things down into smaller components and the Buddhist 'dharma'. But do they talk about "insides" at all? I'm asking because surely everything with a beginning has an inside, but death, which must occur and so begin, can't have an inside in at least some senses, at least supposing that there is no after-life.
