How much self-studying anatomy?

[zamorak]

Current m2. Forgot most of anatomy from first year. 
Which resources should I be using to self-study anatomy for future m3 surgery rotation and eventually NSG subI?

I understand neuroanatomy and anatomy relating to the head/neck region are important for someone interested in NSG.
How important is it to have the details of other anatomic regions memorized (i.e., pelvic region, lower extremity, etc.) at this point?

Surgical Recall. It's all clinically relevant anatomy. Should study the anatomy of the exposure in question at the time you need it. There are equivalent books for NSG as well. I don't remember more than tidbits from general anatomy. The important thing to take away from anatomy (which is being lost in ever shorter anatomy courses) is HOW to learn from anatomy.
