As some one who's taken anatomy in undergrad, including the advanced anatomy in undergrad with cadever lab, I highly reccomend you take Human anatomy, if it is a detailed course. Anatomy at anything beyond the basic level should not be about memorization, rather concepts. If realy soley on memorization, you might reatain some info for a test, but then you will quickly do a brain dump. Also people at my shcool who had a real anatomy in undergrad tended to a little less stressed in anatomy and tended to spend less time on it thereby having more for other subjects. In the end if CVA is not a required course I'd by pass it.
One caveat though if you are not starting next fall, then I would'nt take either anatomy unless you plan on TAing to tutoring it, because you will forget it. For it to really help in med school, you really should take an advaced anatomy that has human cadevers or prosections. Beging anatomy does not scratch the surface of what is taught at Med school.
If you are not starting med school in the fall I highly reccomend takeing Human embryology before takeing anatomy. Embryology will go a long way toward helping you understand important clinical correlations and also understanding Anatomy as well.
Just one side note, never take advice about medical school unless it's form someone who teaches the course at medschool, some one who is currently in med school or from a physician. They tend to know whats going on and what is benificial.
