Reddit reviews Atlas of Human Anatomy (Netter Basic Science)

See if you can get your hands on an anatomy atlas (Netter's Atlas of Human Anatomy, for example). They're extremely detailed, often with photos of musculature, nerves, etc instead of more cartoonish drawings for general learners.

I included the Amazon link for reference, but you can often find them in used bookstores or libraries. If you enjoy having the reference on hand, though, they can be a solid one to have. I would go to a bookstore and look at the different ones available, because some are more photo-heavy, others more drawing-heavy, some separate out systems that you don't need, etc.
