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

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.

CT and Such You’re probably best off working on an interactive system try http://www.imaios.com/en/e-Anatomy CPR Radiograph key from Slice-o lecture is important
