Synaptic and Neuromuscular Transmission
- Previous year questions on Synaptic and Neuromuscular Transmission for NEET PG (National Eligibility cum Entrance Test - Postgraduate), from the Physiology section of the exam.
- Most questions here come from previous-year papers of Indian postgraduate medical entrance and licensing exams; where a paper and year are recorded the question carries them. The image-based questions are original vignettes written around an openly licensed figure, and were never asked in any exam.
- 3 live questions in Synaptic and Neuromuscular Transmission.
- 1 of 3 questions carries a verified exam year: 2019.
- Physiology is worth about 17 of 300 questions on the exam. See every subject’s weightage.
- Question set last updated 19 Aug 2026.

- ARectification
- BAmplification✓ Correct answer
- CInhibition
- DSummation
Q2.Release of synaptic vesicle from presynaptic terminal is inhibited by
- AInhibition of conduction of nerve impulse
- BPrevention of sodium influx
- CPrevention of calcium influx✓ Correct answer
