Why do some colleges teach Anatomy & Physiology in more detail than others? I am currently taking Anatomy & Physiology in college as a pre-requisite for Nursing school and we studied all the bones, but not all the markings. My brother who went to a different college saw what I was studying and he told me that he studied way more markings on the bones than what I was given. The same thing happened when I got to the muscular system. My brother is telling me that he studied twice as many muscles as I was required to. Is there a reason for this?
