OG2.1 | Female Reproductive Anatomy — Summary & Reflection

KEY TAKEAWAYS

Female Reproductive Anatomy — Key Points:

• The vulva includes the mons pubis, labia majora and minora, clitoris, vestibule, and Bartholin's glands (which drain posterior to the vaginal orifice and can form cysts/abscesses).
• The vagina runs upward and backward at ~45°; the posterior fornix is separated from the Pouch of Douglas only by a thin wall.
• The uterus has three layers (perimetrium → myometrium → endometrium) and four parts (fundus, body, isthmus, cervix). The isthmus becomes the lower uterine segment in late pregnancy. The transformation zone of the cervix is the target of Pap smear and the origin of virtually all cervical carcinomas.
• The fallopian tube has four parts (interstitial → isthmus → ampulla → infundibulum); fertilisation occurs in the ampulla, which is also the commonest site of ectopic implantation.
• The ovary is the only pelvic organ not covered by peritoneum, facilitating transperitoneal metastasis of ovarian carcinoma. Lymphatics drain to para-aortic nodes at L1 level.
• Uterine support: the cardinal (Mackenrodt's) ligament is the chief mechanical support; the ureter traverses it ~1–2 cm lateral to the cervix, at risk during hysterectomy.
• Uterine artery = branch of internal iliac artery; ovarian artery = direct aortic branch. The uterine artery crosses above the ureter ('water under the bridge').
• Lymphatics: cervix drains to external iliac + obturator nodes; uterine body to para-aortic; vulva to superficial inguinal.
• The Pouch of Douglas is the most dependent peritoneal recess — the site of free-fluid collection and the route for culdocentesis.

REFLECT

Think about the last pelvic ultrasound report you read or observed being reported. Could you have correctly identified each structure described? Which part of today's anatomy felt most three-dimensional and real to you, and which part remains abstract? Kolb's experiential learning cycle asks us to bridge conceptual knowledge with concrete experience — consider what clinical encounter (bimanual examination, laparoscopy observation, or surgical anatomy demonstration) would most help you consolidate this anatomical map into durable knowledge. Write down one anatomical relationship from this module that you will look for deliberately on your next ward or OT posting.
