Hey! Firstly- I feel your pain!!!! I just completed my first year of OT school and gross anatomy is HELL!!!! I don't know about your program, but in mine people literally just passed anatomy. It takes a crazy amount of work and effort to literally just pass! My course was during first semester, so it was more spread out but we also had other classes to focus on.
I am one of the strange weirdo's that happens to love anatomy, and I was probably the only person in my class who got an A in the course, but that doesn't mean it was easy for me! It took SO much work and studying time to get the grades that I did.
I also had to memorize the origin, insertion, innervation, and action of each muscle. My program gave out a muscles manual and it was 54 pages, divided into three tests. I cut out each muscle with it's info and made flashcards out of them. Then I counted up how many I had, and looked at a calendar. I wrote down the number of flashcards I needed to memorize each night, and also gave myself a night or two to review them all. This was on top of lecture notes that also needed to be memorized, which I did the same thing for.
This first course is really going to determine how you are able to divide your time wisely in OT school. Pace yourself! DO NOT CRAM! My final was cumulative of ALL THE MUSCLES OF THE BODY! Yep, origin, insertion, innervation, and action of every single muscle! If you study correctly, the info will go into your brain the correct way. The key to memorizing is repetition!!!! Take your flashcards with you everywhere, and when you have time pull them out. Review them before you go to sleep, when you get up, when you have extra time. If you go over them the next day and forgot everything (story of my life!) keep repeating it! And it will go into your brain!
I loved cadaver lab! I'm an extremely visual person, so I was able to pick up which muscle was which very quickly- but I helped so many people like you who needed extra help because honestly, the muscles all look the same! A program you might find useful on the Ipad is an app called Muscle Systems Pro III. It's amazing for isolating specific muscles if you're unsure of where it is located/ originates/ inserts. SUNY Downstate has an online cadaver quiz site that's AMAZING!

I used this before each lab practical to quiz myself, and even after each lab session to reinforce what I learned. Do you have a list of specific structures you need to identify in lab? My course did and I always took my list with me to lab. When I found a muscle/vein/artery I wrote a hint down for myself, or tried to draw a pic of it so I could remember it better.
And of course, SPEND AS MUCH TIME IN LAB AS YOU CAN! Go before class, after class, Sundays. As much as you need to! Take an atlas with you, and a study buddy! If your college has tutors take advantage! I know its so hard since you have so much other work to do, but try to find the time! I went with a friend early Sunday morning, between class, during breaks, Fridays. KEEP REPEATING EVERYTHING! Study out loud. Youtube also has great videos of cadavers that I also watched.
Hope this helps! I know it's not easy, but once you get passed anatomy the rest is a breeze!! And if you get through it, you know you could do anything! My friends and I always say that nothing gets worse then anatomy!
YOU WILL GET THROUGH IT! Keep studying! It will get better and you will LOVE OT school! Good luck!
