Comprehensive Test Review (Qns & Ans)
2025
1. Which type of sensory receptor is primarily responsible for
detecting changes in temperature?
- A) Mechanoreceptors
- B) Nociceptors
- C) Thermoreceptors
- D) Photoreceptors
- ANS: C) Thermoreceptors
- Rationale: Thermoreceptors are specialized sensory
receptors that detect changes in temperature.

,2. What is the primary function of the cochlea in the auditory
system?
- A) To amplify sound waves
- B) To convert sound waves into electrical signals
- C) To protect the inner ear
- D) To maintain balance
- ANS: B) To convert sound waves into electrical signals
- Rationale: The cochlea is responsible for converting sound
waves into electrical signals that can be interpreted by the brain.
3. Which part of the eye is responsible for focusing light onto
the retina?
- A) Cornea
- B) Lens
- C) Iris
- D) Pupil
- ANS: B) Lens
- Rationale: The lens focuses light onto the retina, allowing
for clear vision.

,4. The __________ membrane is located in the cochlea and is
crucial for the process of auditory transduction.
- ANS: Basilar
- Rationale: The basilar membrane is located in the cochlea
and plays a key role in auditory transduction by vibrating in
response to sound waves.
5. In the visual system, the __________ is the region of the
retina with the highest concentration of photoreceptor cells.
- ANS: Fovea
- Rationale: The fovea is the region of the retina with the
highest concentration of photoreceptor cells, providing the
sharpest vision.
6. __________ receptors are responsible for detecting pain and
are activated by tissue damage.
- ANS: Nociceptors
- Rationale: Nociceptors are sensory receptors that detect
pain and are activated by tissue damage.
True/False Questions
7. True or False: The semicircular canals in the inner ear are
involved in detecting linear acceleration.
- ANS: False
©/2025
, - Rationale: The semicircular canals are involved in detecting
rotational acceleration, not linear acceleration.
8. True or False: Rod cells in the retina are more sensitive to low
light levels than cone cells.
- ANS: True
- Rationale: Rod cells are more sensitive to low light levels
and are responsible for vision in dim lighting conditions.
9. True or False: Olfactory receptors are responsible for
detecting taste stimuli.
- ANS: False
- Rationale: Olfactory receptors detect smell stimuli, while
taste receptors (gustatory receptors) detect taste stimuli.
Multiple Response Questions
10. Which of the following are primary tastes detected by taste
receptors on the tongue? (Select all that apply)
- A) Sweet
- B) Sour
- C) Bitter
- D) Spicy
