Selected vertebrate skeletons.
Each hip bone is formed by the fusion of three distinct bones that unite in early adulthood. These three components are:12
- Ilium: The blade-shaped, flaring upper part of the hip bone.12
- Ischium: The lower posterior part, which supports the body's weight when seated.12
- Pubis: The lower anterior part of the bone.12
All three bones meet and fuse at the acetabulum, a deep, cup-shaped socket that articulates with the head of the femur to form the hip joint.12
