Gluteus maximus. The hamstrings (semitendinosus, semimembranosus, and biceps femoris) also aid in hip extension however they also perform knee flexion. Therefore gluteus maximus is the power extensor of the hip =)

I also have some additional information to add to the above paragraph. The Gluteus maximus muscle is attached proximally to the ilium posterior to the posterior gluteal line, the dorsal surface of the sacrum and coccyx, and the sacrotuberous ligament; and distally to the iliotibial tract then inserts into the lateral tibial condyle, with some fibres inserting onto the gluteal tuberosity of the femur. It is innervated by the inferior gluteal nerve, the origin of which is spinal levels L5, S1 and S2 in this case. As well as extending the thigh at the hip (hip extension), it assists in the thigh's lateral (external) rotation, steadies the thigh, and assists in raising the trunk from the flexed position.

What is the fuction of the Psoas Major Muscle?
The psoas is one of the flexors of the hip.
Flexes and adducts arm at the shoulder along with pectoralis major?
The Coracobrachialis
Which quadricep muscle has an additional action and what is it?

The gastronemius muscle is one of the calf muscles and it plantar flexes the foot or flexes the knee.
What muscle flexes the hip and knee joints?
The strongest Flexor of the hip (thigh) is illiopsoas muscle which is the merger of the illiacus and the psoas major muscle. The illiacus is on the medial side of the pelvic bone attaching to the femur and the psoas major muscle attaches from the lumbar vertebrae to the femur.
