Sure, so anatomy is 11 units, histology is 5, neuro is 6 I believe. Anatomy runs from August to mid-October; Histo starts right after, ends in mid-March; Neuro runs until the last day of class in May. Let's split histo into 2 units in the fall and 3 units in the spring to make the math easier. So in the fall, you take 13 units of core classes (anatomy + histo) and the other 3 units can come from, seminar classes, anatomical techniques, or grand rounds or a research in anatomical sciences class. You decided what you want to take, though there are suggested options/combinations recommended by the department. In the spring, you have 9 units of core (histo + neuro), again you get the other units from those extra classes offered by the department. For one of the electives, I decided to take Leadership in Health Care in the spring, which I recommend because the seminars are really good and they're very applicable. Other electives I took were Anatomical Techniques, functional anatomy (which is taking physiology alongside med students), and seminars in anatomical research. The program directors assure you that the elective classes won't get in the way of focusing on anatomy and histology. The department is really good about making sure the MS students devote their time to the core curriculum classes.
Regarding your second question, I heard the MS physiology program was very organized, but they don't take physiology alongside the med students. I really liked my MS Anatomy program because you actually can compare yourself to the medical school first-year class and you take anatomy and histology alongside them. Plus, neuroscience is a second-year medical school level class, and although we don't take it alongside med students, we get the same professor who teaches the T2s and neuro is considered a difficult class in med school so taking neuro early on will definitely prepare you! I would overall make the claim that the MS Anatomy program will definitely help prepare you for medical school if that is what you want to do. You actually experience medical school while doing the masters program and gauge if this is something you really want to do with your life. Hope that helps!
