Skin Receptor Matching
This solution details the correct matching of skin receptor types from List-I with their corresponding sensory functions in List-II.
Key Receptor-Function Pairs
Understanding the specific roles of various skin receptors is crucial for identifying the correct matches.
| List-I: Receptor Type | List-II: Sensory Function | Established Association |
|---|---|---|
| (a) Meissner's corpuscles | (iii) Touch | Detects light touch and texture changes. |
| (b) Pacinian corpuscles | (iv) Pressure | Senses deep pressure and high-frequency vibrations. |
| (c) Krauser's end bulbs | (i) Cold | Primarily responsible for detecting cold stimuli. |
| (d) Free nerve ending | (ii) Pain | Responds to noxious stimuli (pain) and temperature variations. |
Conclusion
Based on these established physiological associations, the correct matching combination is:
(a)-(iii); (b)-(iv); (c)-(i); (d)-(ii)
Important Questions from Sense organs - Teaching
- An observer watches the video in which the speaker's lips form the sound 'ga-ga' while the sound trace provides speech that is normally perceived as 'ba-ba'. The conjunction of these conflicting sources produces the perception of 'da-da' which integrates these information and results in which illusion?
- Hold a pencil at arm's length and look at it first with one eye then with the other. There is a little difference between the two views relative to the background. Now bring the pencil just six inches away from your face and try the same thing. This time you will perceive a great difference between the two views. Which one is the correct answer of above example?
- Which of the following is/are true about rhodopsin?
(a) It is a rod pigment that enables vision in low light.
(b) It is a cone pigment that enables vision in bright light.
(c) It is a G-protein coupled receptor.
(d) It is a cone pigment and G-protein coupled receptor.
