Match List-I with List-II and select the correct answer by using the codes given below :
| List-I (Types of Cutaneous Receptors) | List-II (Modality Best Handled) |
|---|---|
| (P) Pacinian corpuscle | (1) Pressure |
| (Q) Ruffini ending | (2) Pain and temperature |
| (R) Merkel ending | (3) Touch |
| (S) Free nerve ending | (4) Vibration |
Answer: C
The correct match is P-4, Q-1, R-3, S-2.
- Pacinian corpuscles, layered and fast-adapting, respond best to vibration.
- Ruffini endings, slow-adapting, respond to sustained pressure and skin stretch.
- Merkel endings (discs) signal light touch and fine detail.
- Free nerve endings carry pain and temperature.
Pairing free nerve endings with pain and temperature and Pacinian corpuscles with vibration is the standard textbook account, and only option C does both.
