Human Uterus's Structure And Adnexae

Description

Uterus, uterine tubes, and ovaries are arranged in a classic adnexal layout within the female pelvis, with the uterine fundus superior to the body and cervix and the uterine cavity oriented toward the cervical canal. From the superolateral uterine cornua, each fallopian tube extends laterally with a gently arched course, ending in the fimbriated infundibulum adjacent to the ovarian poles. The ovaries sit lateral to the uterus, connected medially by the ovarian ligament to the uterine cornu and suspended toward the pelvic sidewall by the suspensory ligament (infundibulopelvic ligament), while the broad ligament provides a peritoneal sheet framing the mesometrium, mesosalpinx, and mesovarium. Midline anatomy. Bilateral symmetry. Adnexal anatomy drives everyday gynecology. The close relationship between fimbriae and the ovary underlies ovum capture and also explains why tubal pathology, including salpingitis and adhesions from pelvic inflammatory disease, increases infertility and ectopic pregnancy risk, most often within the ampulla. Spatial detail at the uterine cornu helps when teaching hysteroscopic tubal ostia, laparoscopic salpingectomy, and where the uterine artery crosses near the cervix, a frequent focus during total hysterectomy to control bleeding while avoiding ureteric injury. Ovarian position relative to the tube also supports discussion of adnexal torsion, where the infundibulopelvic ligament and utero-ovarian ligament form the axis of vascular compromise. Use this illustration in gross anatomy and embryology courses covering the Müllerian derivatives, in OB/GYN curricula discussing adnexal masses and ectopic pregnancy, and in surgical atlases outlining standard approaches to hysterectomy, tubal ligation, and oophorectomy with consistent nomenclature (uterus, uterine tube, ovary, adnexa).
