Organs of the Pelvis

Description

Centered within the female pelvis, the uterus sits in the midline with the cervix projecting inferiorly into the vaginal canal, while the uterine tubes course laterally within the broad ligament toward the ovaries on either side. Superiorly, loops of small intestine and peritoneal folds occupy the lower abdominal cavity and drape into the pelvic inlet, with the sigmoid colon and rectum positioned posterior to the uterus. Anterior to the uterus, the urinary bladder and urethra lie immediately behind the pubic symphysis, separated from the uterus by the vesicouterine pouch. Osseous boundaries of the bony pelvis frame the viscera, and the levator ani and associated pelvic floor fascia form the inferior support layer. Clear midline orientation. This relationship of bladder, uterus, and rectum is the practical map for pelvic surgery and for understanding compartment-based prolapse. During abdominal or vaginal hysterectomy, the course of the ureter just lateral to the cervix beneath the uterine artery (water under the bridge) drives safe ligation technique and helps explain iatrogenic ureteral injury. The depiction also supports teaching of endometriosis distribution in the cul-de-sac (rectouterine pouch) and the clinical relevance of tubo-ovarian anatomy in ectopic pregnancy and adnexal torsion. Use this illustration for gross anatomy and pelvic anatomy modules, OB-GYN and urology lectures, and operative consent materials that need a single view tying reproductive and urinary viscera to the bony pelvis and pelvic floor. It also suits textbooks and review articles on cystocele, uterine prolapse, rectocele, and apical suspension procedures in an adult, light-skinned female subject.
