Final answer:
Pacinian corpuscles are rapidly adapting mechanoreceptors located deep in the skin that detect deep transient pressure and high-frequency vibration.
Step-by-step explanation:
Pacinian corpuscles are rapidly adapting mechanoreceptors located deep in the dermis of both glabrous and hairy skin. They are sensitive to deep transient pressure and high-frequency vibration. Pacinian corpuscles detect pressure and vibration by being compressed, stimulating their internal dendrites. They may help detect vibrations with a frequency of 250Hz.
