@instituteofhumananatomy: The Muscles Behind Your Grip Strength 💪🔬 Fun fact: Only 4 muscles in the upper arm (brachium) but 20 muscles in the forearm (antebrachium)! Several of these bend our fingers (flexion of the digits)—and that's where grip strength comes from! The Cool Part 🤩 See how the superficialis tendon gets SPLIT by the profundus tendon to reach that distal phalanx? This gives us the ability to flex that last finger joint! Together = GRIP STRENGTH! 💪 Your forearm anatomy is more incredible than you thought! 🧠 Follow for More Anatomical Awesomeness! ✨ #gripstrength #forearm #flexordigitorumsuperficialis #flexordigitorumprofundus #carpaltunnel #tendons #humananatomy #cadaverlab #fitness #strengthtraining #anatomyeducation #medstudent #premed

fun fact 15% of people don't have a Palmaris Longus. And I weirdly only have it on my right forearm. You can check by flexing your wrist and doing an Italian hand sign 🤌
