What is the main function of the pelvic girdle?

The primary role of the pelvic girdle is to connect the spine to the lower limbs, providing a stable structure for the attachment of the lower extremities while facilitating movement. This anatomical feature consists of the hip bones, sacrum, and coccyx, working together to support the body's weight as it transfers from the spine to the legs during activities such as walking, running, and standing.

Additionally, this connection is crucial for maintaining balance and stability while allowing a range of motion in the hip joint. The design of the pelvic girdle also plays a significant role in protecting the pelvic organs, including those associated with the urinary and reproductive systems. This combination of support, connection, and protection highlights its essential function in the overall structure and mobility of the human body.
