I posted this in another Case thread -
It's about 50% prosection (pelvic, head & neck), 50% dissection (thorax, abdomen, limb). *Required* anatomy time is kinda minimal, which is great if you hate anatomy or just don't want to spend 6 hours cutting through fat to get to a structure you need, but like others have mentioned, you always have the option of taking an in-depth semester-long gross anatomy course which is great but takes a lot of time.
Talk to older students who've done dissection (i.e. not our current first years, yet) before you form an opinion on the system...two points: 1) I heard it from all the upper classmen, and I echo for a lot of people I know that dissection gets really tiresome...you spend most of your time on unimportant parts (cleaning fat off of the heart to be able to see important structures) and half the time cut through or damage what you're supposed to see and 2) dissection technique is NOT surgical technique...a neurosurg resident once told us not to worry b/c if anything, you have to unlearn dissection technique to learn surgical technique.
Basically, you can definitely go to Case and graduate very strong in anatomy, if you do the free optional extra courses or just work hard at it. But I guess the best way to put it, which could be a pro or con depending on how you look at it, is that we're not required to spend a ton of time on anatomy.
