01 / Location & anatomical relationships
At the back of your pelvis, above your thighs.
02 / Structure & organization
Gluteus maximus forms much of the posterior bulk, with gluteus medius and minimus deeper and more lateral. Subcutaneous fat also contributes to contour. These muscles act on the femur and help stabilize the pelvis during gait.
03 / Function
Large muscles here help you stand up and climb stairs.
04 / Mechanism
The gluteal muscles help move and stabilize the hips. They work when you rise from a chair, climb a step or stand on one leg. Fat and skin cover these muscles and help cushion sitting.

Connect structure with function
Hip extension is prominent when rising or climbing. The smaller gluteal muscles help keep the pelvis level while the opposite foot is off the ground.
Check your understanding
Locate the buttocks in relation to its neighbors. Explain how the structural features described above support its function, then distinguish it from a nearby structure with a different role.
