In my opinion, the best way to learn anatomy is to see it unfold before you during surgery.
When I was a pgy2, I would get into the OR as much as possible to watch or participate in the surgeries. Many times it was just watching. If there was a surgery going on while I was on call, I did my best to be in the OR and letting consults that weren't urgent/emergent wait.
There are days when I'm in the OR with a chief and the juniors are nowhere to be found. Usually the chief knows what's going on, and typically the junior is doing menial tasks that can wait. There sometimes is a sentiment that if the junior isn't going to get to do anything then the experience isn't valuable.
Anyway, show up to the OR. There's always great anatomy there.
Beyond that, look for particular papers that focus on limited aspects of anatomy. For example, there are tons of great papers on the anatomy of the facial nerve or anatomy of the trigeminal nerve. Always good stuff.
