Studying anatomy requires memorization of facts (muscle origins, nerve fibers, etc) and 3 dimensional conceptualization. You can use tables and mnemonics to memorize facts like aterial branches, etc. The 3D mapping of the body is what takes work.
I would encourage you to think of an organ or region of the body as you are studying and mentally try to list and position every structure surrounding it. For example, think of the mandibular ramus. Now think of what is superior, inferior, medial, lateral, anterior, and posterior to the ramus. Now, name the blood and neurologic supply to the muscles and glands you named. If you can think like that, you will master anatomy.
Finally, anatomic spaces are important. You should be able to define the infratemporal fossae, the borders of the posterior mediastinum, and the difference in intra and extraperitoneal structures. Use atlases and cadavers to help.
