Neuromuscular Junction MCQs with case scenarios
36 clinical vignettes mapped to competencies PY 3.4, PY 3.5 and PY 3.6 — junction structure and impulse transmission, neuromuscular blocking agents, and the pathophysiology of myasthenia gravis. Every item reveals a worked explanation and a take-home pearl the moment you answer.

The three competencies
Each set runs as a standalone 12-question assessment. Answers are revealed one question at a time, with the reasoning spelled out.
PY 3.5
Action of neuromuscular blocking agents
- Depolarizing: succinylcholine
- Non-depolarizing: vecuronium
- Reversal: neostigmine, sugammadex
PY 3.6
Pathophysiology of myasthenia gravis
- Autoimmune AChR destruction
- Ptosis & fatigable weakness
- AChR antibodies, edrophonium test
- Anticholinesterases, immunosuppressants
The competency map
The question bank is built directly from this chart, so every item traces back to one of the listed learning objectives.
How the assessment works
Start from a case
Every question opens with a clinical vignette — a burns patient given succinylcholine, an infant fed honey, a woman whose ptosis worsens by evening.
Answer and learn at once
Choosing an option immediately marks it right or wrong, shows the correct answer and explains the underlying mechanism rather than just naming it.
Close the loop
The score screen lists the pearls behind the items you missed, offers a full review of all questions, and reshuffles the set for another attempt.

The mixed assessment draws all 36 cases from the three competencies in random order — the closest thing to how these topics actually appear in an exam.
