[1] [2] This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure.

The large mechanoreceptors—Pacinian corpuscles and Ruffini endings—are located in the lower layers and respond to deeper touch. WebMerkel disk receptors respond maximally to low frequencies (5–15 Hz), Meissner’s corpuscles to mid-range frequencies (20–50 Hz), and pacinian corpuscles to high frequencies (60– 400Hz).Receptortuningthresholdsdeterminethecapacityto detect vibration. blow smoke up arse meaning
