What is the function of the sartorius muscle in a fetal pig?

In quadruped animals such as pigs, the sartorius muscle acts to adduct the hind leg, meaning it pulls the leg inward toward the center of the body. The sartorius muscle is located in the thigh and runs from the hip joint along the inside of the thigh to the knee.

In the bipedal human body, the sartorius muscle moves the leg forward and sideways, and rotates the leg at the hip joint. It is also the major muscle involved in pulling the foot and ankle towards the other leg in order to sit cross-legged or sit with one leg resting on the knee of the other leg.
