Does our conventional body belong to the external sense bases?

There are six internal sense bases named eye, ear, nose, tongue, body, and mind. There are six external sense bases named visible form, sound, odour, taste, and mental objects. I have two parts in my question; 1. If we look at our own hand, leg, or any other conventional body part or if we touch and feel our own conventional body, do all these belong to the external sense bases? 2. If the answer is "yes" to the first part of the question, which form elements (rūpa) are included in internal?
