Motor Control: Descending Pathways and Cortical Control
- Previous year questions on Motor Control: Descending Pathways and Cortical Control 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.
- 4 live questions in Motor Control: Descending Pathways and Cortical Control.
- 2 of 4 questions carry a verified exam year: 2018, 2019.
- Physiology is worth about 17 of 300 questions on the exam. See every subject’s weightage.
- Question set last updated 19 Aug 2026.
Q1.Concurrent flexion of both wrists in response to electrical stimulation is characteristic of which area of the nervous system?
- APostcentral gyrus
- BVestibulospinal tract
- CDentate nucleus
- DSupplementary motor cortex✓ Correct answer
Q2.All are true about Decerebrate posture EXCEPT
- AExaggerated gamma motor neuron discharge
- BReticulospinal tract is involved
- CExtension of both upper and lower extremity
- DFlexion of upper extremity and extension of lower extremity✓ Correct answer
Q3.According to Sherrington classification, the decerebrate rigidity is characterized by all except
- ARigidity occurs in all the muscles of the body✓ Correct answer
- BIncrease in the rate of discharge of the gamma efferent neuron
- CIncreased excitability of the motor neuron pool
- DDecerebration produces no phenomenon akin to spinal shock
Q4.Maximum area in homunculus signifies?
