I'm a dental student studying gross anatomy. Usually, students don't have enough skill in disecting the cavador to all stuctures (arteries, muscles, vein, nerves) they've studied. This reference help me improving and completing my lab skill. Its pictures are all color. They're all real picture. All structure are all clear. (clean fascia very clearly) Some sturctures are dyed so they help you identify and understand it easier.It's the best lab reference book I've ever had.
