PMDC NLE — Physiology MCQs
Practice 10 Physiology past-paper MCQs for PMDC NLE, each with a detailed explanation and reference. Try free samples below, then start a full quiz.
Physiology is a core part of the PMDC NLE syllabus. HighYield's Physiology question bank collects 10MCQs modelled on real past papers, so you practise the exact style and difficulty you'll face on exam day. Every question comes with a worked explanation and a subject reference, so you learn why an answer is right — not just which option to pick.
Work through Physiology in Tutor mode to learn as you go, or switch to Timed mode to simulate real exam pressure. Your accuracy is tracked per subject, so you always know whether Physiology is a strength to maintain or a weak area to drill.
Sample Physiology Questions
A CT scan of a 62-year-old man shows damage to Broca's area of the cortex. What deficit best describes the result of this damage?
- A.Inability to use both hands to grasp an object (reflects parietal/motor coordination, not Broca's area)
- B.Spastic paralysis of the contralateral hand (a primary motor cortex lesion causes this, not a Broca's area lesion)
- C.Paralysis of the laryngeal and pharyngeal muscles (this reflects brainstem, not Broca's area, function)
- D.Inability to speak whole words correctly
A man steps on a sharp stone while walking. Which reflexes are triggered?
- A.Withdrawal reflex in the affected limb, and crossed extensor reflex in the opposite limb
- B.Stretch reflex in the affected limb, and crossed extensor reflex in the opposite limb (stretch reflex is not the mechanism triggered by pain)
- C.Stretch reflex in the affected limb, and withdrawal reflex in the opposite limb (stretch reflex is not the mechanism triggered by pain)
- D.Crossed extensor reflex in the affected limb, and withdrawal reflex in the opposite limb (the reflexes are reversed here)
A marathon runner experiences muscle fatigue toward the end of a race despite an adequate oxygen supply. What is the most likely physiological cause?
- A.Increased calcium release from the sarcoplasmic reticulum (this would enhance, not impair, contraction)
- B.Glycogen depletion
- C.Depletion of ATP stores (resting ATP stores are tightly regulated and rarely become the limiting factor)
- D.Failure of neuromuscular transmission (rare in normal endurance fatigue)
