Final answer:
The pelvic girdle attaches the lower limbs to the torso and is responsible for stability and locomotion. The muscles that move the femur originate from the pelvic girdle and provide power and stability to the body.
Step-by-step explanation:
The pelvis, also known as the pelvic girdle, attaches the lower limbs to the torso. It is responsible for bearing the weight of the body and facilitating locomotion. The pelvic girdle consists of two large hip bones that join together at the pubic symphysis in the front and with the sacrum at the back.
The range of motion in the pelvic girdle is limited compared to the pectoral girdle, which is important for stability and posture. The muscles that move the femur, such as the gluteal muscles, originate from the pelvic girdle and provide power and stability to the body.
