Anatomy is a core subject in MRCS Part A, and understanding applied anatomy is essential to tackle clinical scenario-based questions. The paper tests not just memorization but your ability to connect anatomy with surgical pathology and operative techniques.
Must-Know Anatomy Topics for MRCS Part A
1. Nerve Supply of Upper and Lower Limbs
This is a high-yield area in the MRCS exam. Expect questions on:
- Brachial Plexus: Roots, trunks, divisions, cords, branches
- Clinical scenarios: Erb’s palsy, Klumpke’s paralysis, axillary nerve injury
- Peripheral Nerves of the Arm: Radial, median, ulnar
- Motor and sensory distribution
- Sites of injury and surgical relevance
- Lumbosacral Plexus: Femoral, sciatic, obturator nerves
- Foot drop, meralgia paresthetica, femoral nerve palsy
Mortimer Green Tip: Use interactive diagrams and MCQs on nerve lesions to strengthen clinical correlations.
2. Breast Anatomy
Understand both gross and surgical anatomy, especially:
- Lymphatic drainage of the breast (levels I, II, III)
- Axillary tail (of Spence)
- Nerve supply: Intercostobrachial nerve and long thoracic nerve
- Surgical landmarks during mastectomy
- Applied anatomy in breast cancer staging
Common Exam Theme: Nerve injured during axillary node clearance? (Answer: Long thoracic nerve)
3. Abdomen and Pelvis: Ligaments, Arteries, and Nerves
The abdomen and pelvis are tested in anatomy, pathology, and surgery MCQs.
- Peritoneal Ligaments: Falciform, gastrohepatic, splenorenal, etc.
- Arteries:
- Celiac trunk, SMA, IMA
- Internal iliac artery branches
- Blood supply of the rectum and anal canal
- Nerve Supply:
- Autonomic innervation (sympathetic & parasympathetic)
- Pelvic splanchnic nerves, pudendal nerve
- Referred pain patterns
Mortimer Green App includes cross-sectional anatomy images and applied MCQs on pelvic vessels and nerve injuries.
4. Brain and Neurological Deficits
This is an interdisciplinary topic—often tested in anatomy, neurology, and clinical medicine sections.
- Cortical Areas:
- Motor and sensory homunculus
- Broca’s and Wernicke’s areas
- Cranial Nerves: Course, function, and lesion effects
- Brainstem Syndromes: Weber’s, Millard-Gubler, Wallenberg, etc.
- Vascular Territories: MCA, ACA, PCA strokes and their deficits
- Cerebellum & Basal Ganglia: Ataxia, tremor, Parkinsonian symptoms
Case-Based MCQs often test your ability to localize neurological deficits based on lesion site—covered thoroughly in Mortimer Green mock tests.
