The earliest known members of the group are the enantiornitheans "Protopteryx
Gross anatomy 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. Gross anatomy Gross anatomy (also called topographical anatomy) is the study of anatomy at the visible (macroscopic) level. Gross anatomy is studied using both invasive and noninvasive methods with the goal of obtaining information about the macroscopic structure and organization of organs and organ systems.
