For me it is easiest to remember the innervations and actions if you group muscles together in compartments (especially if you know your anterior and posterior divisions of the brachial and lumbosacral plexi)...for example the hip adducters are almost all innervated by the obturator nerve, the Hamstrings are innervated by the tibial branch of the sciatic, the Musculocutaneous nerve innervates the elbow flexors--biceps brachii, coracobrachialis and brachialis, the forarm flexors are innervated by anterior div nerves (ulnar and median) and extensors by posterior div (radial). It is also easier to try to learn the origin/insertion of a muscle and use that to figure out the action--all you gotta do is be able to predict what would happen if you shortened that muscle...makes learning things like why the right sternocleidomastoid would rotate the head to the left but would tilt it to the right. Figure out what works best for you though, no one learns the same way, I am horrible at memorization (which is how most people learn anatomy), but I'm really good at figuring out ways to think through things to get to the right answer.
how did u come to figure out the rite way for u? I have to learn upper lower and thorax in less than a month
Good Luck!!
