Since 1975, the Oklahoma Notes have been among the most widely used reviews for medical students preparing for Step 1 of the United States Medical Licensing Examination. OKN: Anatomy takes a unified approach to the subject, covering Embryology, Neuroanatomy, Histology, and Gross Anatomy. Like other Oklahoma Notes, Anatomy contains self-assessment questions, geared to the current USMLE format; tables and figures to promote rapid self-assessment and review; a low price; and coverage of just the information needed to ensure Boards success.
