Which type of sensory structures carry deep pressure and vibration sensations______________?
Correct answer: C. Pacinian corpuscles
- A. Hair end organs
- B. Meissner's Corpuscles
- C. Pacinian corpuscles
- D. none of these
Explanation
Pacinian corpuscles are rapidly adapting mechanoreceptors located deep in the skin and subcutaneous tissues, where they detect deep pressure and high-frequency vibration. Meissner's corpuscles mainly detect light touch and low-frequency vibration near the skin surface. The likely alternative is Meissner's corpuscles because they also sense touch, but they are not the main receptors for deep pressure.
