The Basement Membrane

Jonathan Reisman writes about his medical student days, specifically the basement membrane (which is fascial, and relates to Tom Myers' "double bagged" metaphor).  While learning from his cadaver and his histology class he got the notion to improve his perspective on anatomy by observing at a nearby slaughterhouse. On that day he had "a central insight of anatomy and histology would take shape for me. It was there that I would learn something about the border between our bodies and the rest of the universe".  Get the full insight here.
