The gracilis muscle (m. gracilis) is flat, long, and located superficially along the entire length of the medial surface of the thigh. It begins with a short tendon on the lower half of the pubic symphysis and on the lower branch of the pubic bone. In the lower third of the thigh, the belly is located between the sartorius and semimembranosus muscles. The tendon of the gracilis muscle is attached to the medial surface of the upper part of the body of the tibia and participates in the formation of the superficial goose foot.
Function of the gracilis muscle: adducts the thigh; flexes the leg, simultaneously rotating it inward.
Innervation of the gracilis muscle: obturator nerve (LII-LIII).
Blood supply of the gracilis muscle: obturator, femoral and external pudendal arteries.
