This USMLE step 1 book is a lot more dense than the title implies. With over 180 pages, it does provide a good basis for anatomy based pathology. The MRI pictures are great. Key chapters would be heart, lung, upper extremity, spine, and lower extremity. Anatomy of the upper limb is extremely high yield review. A good understanding of the nerves and muscle enervation of the hands and arms will help answering several questions. An other priority is to understand fractures and their related deficiencies.
