Cadavers are rather expensive and hard to come by so you probably would be hard pressed to find an undergraduate anatomy course with any significant degree of actual human dissection. Also dissection is a definite skill and dissecting a person tends to be somewhat more difficult than what you find with say a cat. The other problem is that human anatomy is seldom as easy to distinguish as it is in books so it's easy to destroy or miss important structures (nerves come to mind) if one is either inexperienced (undergraduates), inept (most undergraduates), inattentive (think ADHD which could be more or less a criteria to be attracted to EMS based on a lot of my former partners and students) or just plain lazy (the vast majority of undergraduates).
