Correct answer: C — Recurrent laryngeal nerve
The recurrent laryngeal nerve supplies most intrinsic laryngeal muscles. Median nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Ischial spine is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Ligamentum flavum is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Radial nerve is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. In Primary FRCA anatomy, the tested structure should explain the block, airway sign or regional complication in the stem.
