Musculus gracilis

The gracilis muscle is part of the adductor group in the hip, which includes several muscles that extend between the pelvis and femur. It is unique as the only two-jointed muscle in this group, running from the inferior ramus of the OS pubis to the tibial tuberosity. The gracilis muscle is innervated by the obturatory nerve and primarily functions in hip adduction and flexion, as well as knee flexion and internal rotation. These muscles are crucial for leg crossing and pelvic stabilization.

Which group of muscles does the gracilis muscle belong to?

• Extensor group

• Abductor group

• Flexor group

• Adductor group
