Day 07

Detailed notes For MRCS Part A you are not tested on lymph physiology in detail — you are tested on which nodes drain which organ, because that determines where cancers metastasise and where surgeons must dissect. Two principles unlock most questions: 1. Lymphatics follow arteries — drainage of a gut segment mirrors

👩‍⚕️ Thyroid is one of the most heavily examined organs in MRCS Part A. Examiners love it because it links anatomy (recurrent laryngeal nerve, parathyroids, blood supply), physiology (TSH–T4–T3 axis), pathology (autoimmune disease, four cancers with distinct biology) and surgery (four classic post-thyroidectomy complications). Master those four axes

# 31 NECK LUMPS Neck lumps are an examiner's playground. They reward candidates who can map a clinical sign to an anatomical compartment, then collapse the differential by age and behaviour of the lump. The trick is not memorising every lesion — it is having a reproducible system: where is

# 33 OTOLARYNGOLOGY ENT comes up reliably in MRCS Part A because it sits at the crossroads of head and neck anatomy, embryology, microbiology and acute surgical management. This chapter teaches the topic the way examiners test it: anatomy first, then the conditions, then the SBAs. Detailed notes Anatomy of the
