Q1 · Synaptic Transmission
NEET PGMediumExplanation
Depolarisation opens voltage-gated calcium channels, and calcium influx triggers vesicle fusion and neurotransmitter release into the synaptic cleft. This is the calcium-dependent step of synaptic transmission.
Q2 · Ascending Tracts
NEET PGMediumExplanation
The lateral spinothalamic tract carries pain and temperature, crossing near the level of entry. The dorsal columns carry fine touch, vibration and proprioception, crossing in the medulla.
Q3 · Motor Pathways
HardExplanation
About 85 to 90% of corticospinal fibres cross at the pyramidal decussation in the medulla to form the lateral corticospinal tract, which controls voluntary movement of the limbs on the opposite side.
Q4 · Reflexes
EasyExplanation
The patellar reflex is a monosynaptic stretch reflex: muscle spindle afferents synapse directly on alpha motor neurons, causing quadriceps contraction. It tests the L2 to L4 spinal segments.
Q5 · Cerebellar Function
MediumExplanation
Cerebellar lesions cause intention tremor, ataxia, dysmetria, dysdiadochokinesia and nystagmus, with signs ipsilateral to the lesion. Resting tremor and rigidity instead suggest basal ganglia, or Parkinsonian, pathology.
Q6 · Electroencephalography
MediumExplanation
Alpha waves at 8 to 13 Hz dominate in an awake, relaxed adult with eyes closed. Beta waves appear with mental activity, delta waves occur in deep sleep, and theta waves appear in drowsiness and in children.
Q7 · Autonomic Nervous System
EasyExplanation
Most postganglionic sympathetic fibres release noradrenaline. An exception is sweat glands, which use acetylcholine. All preganglionic autonomic fibres and postganglionic parasympathetic fibres use acetylcholine.
Q8 · Pain Pathways
HardExplanation
A-delta fibres are thinly myelinated and carry fast, sharp, well-localised first pain. Unmyelinated C fibres carry slow, dull, poorly localised second pain and temperature.
Q9 · Vision
MediumExplanation
Cones mediate colour vision and high-acuity central vision in bright, photopic conditions and are concentrated at the fovea. Rods handle dim-light, scotopic vision and are more sensitive but do not detect colour.
Q10 · Hypothalamus
EasyExplanation
The hypothalamus regulates body temperature, hunger, thirst and circadian rhythms, and links the nervous and endocrine systems via the pituitary. It is central to homeostasis.
Neurophysiology sits within Physiology, which carries the same syllabus in both exams. This set runs to 10 questions, each tagged Easy, Medium or Hard, 2 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Neurophysiology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this Neurophysiology set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Neurophysiology sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
