. Many schools provide students with

s for investigation by dissection, aided by dissection manuals, as well as cadaveric atlases (e.g. Netter's, Rohen's). Working intimately with a cadaver during a gross anatomy course has been shown to capture the essence of the patient-provider relationship. However, the expense of maintaining cadaveric dissection facilities has limited the time and resources available for gross anatomy teaching in many medical schools, with some adopting alternative prosection-based or simulated teaching. This, coupled with decreasing time dedicated to gross anatomical courses within the growing greater medical school curriculum, has caused controversy surrounding the sufficiency of anatomical teaching with nearly half of newly qualified doctors believing they received insufficient anatomy teaching. Medical schools have implemented on-screen anatomical lessons and tutorials to teach students surgical procedures. The use of technological visual aids and gross dissection are more effective together than either approach alone. Recently, online flashcards and quizzes have been used as well.
