Correct answer: E — Saphenous nerve
The saphenous nerve supplies the medial leg and ankle. Between internal oblique and transversus abdominis is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. C3 to C5 roots is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Thoracic paravertebral space is less appropriate because it would fit a different clinical clue or a separate anaesthetic problem. Internal superior laryngeal 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.
