The pelvis is a bony structure located at the base of the spine, connecting the trunk to the lower limbs. It consists of several bones, including the ilium, ischium, and pubis, which together form a ring-like shape. The pelvis supports the weight of the upper body when sitting and standing, and it plays a crucial role in movement and balance. In addition to its structural functions, the pelvis also houses and protects vital organs in the reproductive and urinary systems. It provides attachment points for various muscles and ligaments, contributing to the stability and mobility of the hip joint.
