01 / Location & anatomical relationships
On each side where your thigh meets your pelvis.
02 / Structure & organization
The femoral head fits into the acetabulum of the pelvis. Articular cartilage, a fibrocartilaginous labrum and a strong capsule support a stable weight-bearing joint. Surrounding muscle groups produce flexion, extension, abduction and rotation.
03 / Function
Its ball-and-socket joint lets your leg move in several directions.
04 / Mechanism
The round head of the femur fits into a cup-shaped socket in the pelvis. Cartilage helps the surfaces glide, while ligaments and muscles keep the joint stable. This arrangement permits bending and rotation.

Connect structure with function
The hip balances mobility with stability. Compare its deep socket with the shallower shoulder socket to understand why their movement ranges differ.
Check your understanding
Locate the hip 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.
