Socket (acetabulum)

The socket of the acetabulum is a cup-shaped part of the pelvis bone that forms the hip joint by accommodating the head of the thigh bone (femur). It acts as a stable and smooth surface allowing the leg to move and bear weight during activities like walking and running. The acetabulum's shape and structure provide support, stability, and flexibility to the hip joint, crucial for mobility and everyday movement. It is reinforced by cartilage, ligaments, and muscles that help protect the joint and facilitate smooth motion.
