1. Slacker’s Guide to Thoracic Gross Anatomy
Prepared by Mike Ori

2. Caveat Emptor
As with all slackers guides, I have omitted, condensed, and misunderstood information so don’t complain if I got something wrong, after all, you’re a slacker.
Also, it goes without saying that the faculty has not vetted the information in any way. Always refer to their notes and lectures for the last word.

3. CT and Such
You’re probably best off working on an interactive system try
CPR Radiograph key from Slice-o lecture is important
