This document provides an overview of female pelvic anatomy. It describes the bony pelvis and its joints, as well as the pelvic openings. It then discusses the pelvic floor muscles, fascia, and ligaments. The document outlines the blood supply, lymphatic drainage, and innervation of the pelvic region. It also reviews the internal pelvic organs and perineal structures in detail.
