If I were to go up to a doctor and ask them, "Name me one book that you recall from medical school," I would wager that a large majority of them would reply "Netter", especially surgeons. Dr. Frank Netter was a physician and artist who made a monumental contribution to the training of physicians. He drew hundreds of illustrations detailing the human physique at every level. It's the one book that I can guarantee that I will keep and even reuse again and again over my career. While I'll never be a surgeon, I find these images to be beautiful and mesmerizing in their own right. And yes, I had to learn all of these details and then some.
