I can only comment for Australia and unfortunately there the answer is Yes! The main origin and insertions are important and which lies medial/lateral to what. This is impt in the diagnosis of conditions that may affect several structures that lie in close proximity to one another. Purchasing a good anatomy atlas and a 3D CD such as those from primal pictures would be a great study aid that you will use long into your professional life. Also the Primal CD's have great quizzes on landmarks and more. I can recommend highly the following anatomy text book/ color atlas as the gold standard for any student of anatomy: Color Atlas of Anatomy
