The flexor pollicis longus (/ˈflɛksərˈpɒlɪsɪsˈlɒŋɡəs/; FPL, Latin flexor, bender; pollicis, of the thumb; longus, long) is a muscle in the forearm and hand that flexes the thumb. It lies in the same plane as the flexor digitorum profundus. This muscle is unique to humans, being either rudimentary or absent in other primates.[1] A meta-analysis indicated accessory flexor pollicis longus is present in around 48% of the population.[2]
