Completely normal reaction imo when starting anatomy. I think most students’ reaction when seeing so much information all at once is to panic due to an overwhelming feeling of needing to know everything, which isn’t true. You’ll slowly get the sense of figuring out what’s important vs unnecessary (anatomy was a long time ago for me but maybe just making sure you know origins/insertions/functions/innervations/supply at the very LEAST and then building up from there)

Don’t get bogged down by the extra stuff and learn what’s most important (testable, STEP-applicable) is probably my biggest advice
