what are the muscles of the groin
Adductor Magnus is the largest groin muscle and is one of the two long adductor muscles (gracilis is the other). It is usually described as having two parts, hamstring and adductor parts. It adducts, flexes and internally rotates the hip.
Adductor Brevis. Adductor Brevis is the smallest and shortest of the three short adductor muscles. It originates on the pelvis and inserts into the thigh bone and adducts inwards and flexes the hip out forwards. It is most commonly injured in a groin strain.
The inguinal ligament supports the muscles that run inferior to its fibers, including the iliopsoas and pectineus muscles of the hip. It also supports the nerves and blood vessels of the leg as they pass through the groin, including the femoral artery, femoral vein, and femoral nerve. The support provided by the inguinal ligament is important to maintaining the flexibility of the hip region while allowing vital blood and nerve supply to the leg.
