MRCOG Part 1: Anatomy
Anatomy in MRCOG Part 1 focuses almost entirely on clinically relevant anatomy for obstetrics and gynaecology — pelvic anatomy, the reproductive tract, the perineum, and surgical anatomy of importance in O&G procedures. Approximately 85 questions.
Topics Covered
Pelvic Anatomy
- ›Bony pelvis — types (gynaecoid, android, anthropoid, platypelloid) and obstetric dimensions
- ›Pelvic floor muscles — levator ani components, pudendal nerve
- ›Pelvic fascia, ligaments — uterosacral, cardinal (Mackenrodt's), round ligament
- ›Peritoneum and pouches — pouch of Douglas (rectouterine), vesicouterine pouch
Reproductive Tract
- ›Uterus — layers (endometrium, myometrium, perimetrium), blood supply (uterine artery), relations
- ›Cervix — internal and external os, transformation zone
- ›Fallopian tubes — parts (interstitial, isthmus, ampulla, infundibulum), blood supply
- ›Ovary — position, ligaments (ovarian ligament, suspensory ligament), blood supply (ovarian artery)
- ›Vagina — relations, fornices, blood supply, lymphatic drainage
Surgical Anatomy
- ›Ureter — course through pelvis, relation to uterine artery ("water under the bridge")
- ›Ureter in relation to uterosacral ligaments and cardinal ligaments — risk of injury
- ›Bladder — position, trigone, relation to uterus and cervix
- ›Rectum — relation to posterior vagina and rectovaginal septum
- ›Inguinal canal — structures, hernia types, round ligament passage
Perineum & Vulva
- ›Vulva — labia majora, minora, clitoris, vestibule, Bartholin's glands
- ›Perineal body — muscles attached, obstetric importance
- ›Anal sphincter — external (voluntary, pudendal nerve) vs internal (involuntary, autonomic)
- ›Lymphatic drainage — vulva and lower vagina to inguinal nodes; upper vagina and cervix to iliac nodes
Exam Tips for Anatomy
The ureter course is one of the most tested anatomy topics — know exactly where it is at risk in hysterectomy ("water under the bridge").
Lymphatic drainage is regularly tested: know the difference between vulval/lower vaginal drainage (inguinal) and upper vaginal/cervical drainage (iliac).
Bony pelvis types and their obstetric implications are tested — gynaecoid is the most favourable for vaginal delivery.
The relations of the pelvic organs to each other are tested as scenario-based questions about surgical risks.
Know the pudendal nerve path (Alcock's canal) and what structures it innervates — relevant to perineal anaesthesia.
