Special Senses is part of the Central Nervous System section of Physiology. Practise 24 exam-style MCQs for NEET PG, FMGE, INI-CET and NEET SS, each with the correct answer and a detailed explanation.
Bitter taste at the tongue's posterior third, the photoreceptor-to-ganglion order of the optic pathway and glutamate release from hair cells anchor these Special Senses MCQs, which test vision, hearing and taste as high-yield NEET PG revision.
Sample Special Senses MCQs with answers
Sample MCQ #1
The receptors/buds responsible for carrying bitter taste sensation are situated
AAt the tip of the tongue
BJust behind the tip
CAt the sides
DAt the posterior aspect
Show Answer & Explanation ▾
✓ Correct Answer: D. At the posterior aspect
Tip of the tongue - sweet (more sensitive) Posterior part of tongue - bitter Sides of tongue - salt and sour taste Reference: Ganong, 25th edition page no. 222
Sample MCQ #2
First order neuron in optic pathway is:
ABipolar cell
BGanglion cell
CHorizontal cell
DPhotoreceptors
Show Answer & Explanation ▾
✓ Correct Answer: D. Photoreceptors
Photoreceptors are first order neurons Bipolar cell is second order neuron Ganglion cell is third order neuron Reference: Ganong 25th edition page no.178
Sample MCQ #3
Direction of sound is differentiated by
AAuditory cortex
BMedial geniculate body
CLateral geniculate body
DInferior colliculus
Show Answer & Explanation ▾
✓ Correct Answer: D. Inferior colliculus
All auditory pathways ascending through the brain stem converge in inferior colliculus Helps in localization of sound and the direction from which the sound comes Reference: Kandel, Principle of Neural Sciences, 5th edition page no.697
Sample MCQ #4
Neurotransmitter released by inner hair cells during depolarisation is
AGlutamate
BGlycine
CAcetylcholine
DGABA
Show Answer & Explanation ▾
✓ Correct Answer: A. Glutamate
Depolarization of hair cells release a neurotr ans mitter glutamate, which initiates depolarization of neighboring afferent neurons Reference: Ganong 25th edition page no.204
Sample MCQ #5
The rod receptor potential differs from other sensory receptors in that it shows
ADepolarization
BDecreased negative
CIncreased conductance of sodium
DHyperpolarization
Show Answer & Explanation ▾
✓ Correct Answer: D. Hyperpolarization
"Vision is the only sense wherein activation of receptors leads to hyperpolarization (EYEperpolarisation)" Reference: Ganong, 25th edition page no.179
Sample MCQ #6
False regarding papillae of tongue
AFungiform papillae at tip
BCircumvallate papillae at base
CFoliate papillae at back edge
DFiliform papillae have taste buds at tip
Show Answer & Explanation ▾
✓ Correct Answer: D. Filiform papillae have taste buds at tip
Taste buds are present in papillae of the tongue Fungiform, circumvallate, foliate papillae have taste buds Filiform papillae don't have any taste buds Reference: Ganong, 25th edition page no.222
Sample MCQ #7
Photoreceptors on exposure to dark release
AAcetylcholine
BGlutamate
CAdrenaline
DEpinephrine
Show Answer & Explanation ▾
✓ Correct Answer: B. Glutamate
Neurotr ans mitter stored rods and cones terminal endings is glutamate Reference: Ganong, 25th edition page no.179
