I need some help getting prepared so I can pass these last two semesters

I’m currently on summer break right now. Next semester I’m going to have a class on cross sectional anatomy. I heard from not all but a few people that it’s a brutal class. So I would like to start reading about it to give myself a good start and make the class go a little smoother for me. I had my sister give me her notes/book on the class to me so I’ll be looking at that. I texted my friend who just graduated and asked where I should start and she said I should look at the vessels and veins of the brain. What I really need is a picture of it with all the things labeled. Is there any specific sites or links that can really help me? Thanks.
