The gluteus maximus is located superior to which muscle

The gluteus maximus is located superior to the gastrocnemius muscle.

The gluteus maximus is the most superficial gluteal muscle and the main extensor muscle of the hip. The group of the gluteal muscles includes the gluteus maximus, gluteus medius, gluteus minimus and tensor fasciae latae.  The gluteus maximus is a thick muscle that has a quadrangular shape. It is responsible for the maintenance of keeping the upper body erect.The gastrocnemius muscle, also known as leg triceps, is an important muscle that is required for walking and running. This muscle is located on the back portion of the lower leg.  The tendon of the gastrocnemius muscle is joined with the tendon of the soleus muscle and both form the Achilles tendon and attach to the calcaneus (i.e., the heel bone).
