Used in detecting pressure in fingertips, palms, soles of the feet, and other hairless skin regions.
Pacinian corpuscle is sensitive to deep pressure.
The Pacinian corpuscle responds to "mechanical" pressure i.e. touch.

Pressure is the sensation associated with activation of the lamellated corpuscle in the skin. The laminated corpuscle is also referred to as the Pacinian corpuscle.
The pacinian corpuscle is present in the dermis layer of the skin. Its function is to detect deep pressure and vibration.

The efflux of potassium ions is maintained by passive potassium channels.
Whilst all of these things are within the dermis of the skin, the arrector pili is the odd thing out. The arrector pili is a muscle where as the rest (meissner, pacinian and merkel) are nerve endings. The result of contraction of arrector pili is the standing up of a hair. The meissner corpuscle is a sensory nerve ending that is specific for fine touch, as are merkel cells [light touch]. The pacinian corpuscle is a nerve ending specific for sensation of deep pressure and vibration.
Pacinian corpuscles are onion-shaped receptors that respond to deep pressure. They are found in the skin and are sensitive to mechanical stimuli. When pressure is applied to the skin, these receptors generate nerve impulses that travel to the brain, allowing us to perceive the sensation of deep pressure.
Mechanoreceptors are part of the nervous system that detect changes in movement or pressure. They are a cutaneous receptor found in the dermis or epidermis. They involve special tiny organs. These include cutaneous mechanoreceptors (for light touch), Ruffini's end organ (sustained pressure), Meissner's corpuscle (changes in texture, slow vibrations), Pacinian corpuscle (deep pressure, fast vibrations) and Merkel's disc (sustained touch and pressure).
