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.
The Pacinian corpuscle is located in the peripheral nervous system (PNS). It is a type of mechanoreceptor found in various tissues, including the skin and joints, and is responsible for detecting deep pressure and vibration. These sensory receptors transmit signals to the central nervous system (CNS) for processing but are themselves part of the PNS.
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.
The integumentary structure that functions to sense heavy pressure is the Pacinian corpuscle, also known as a lamellar corpuscle. These specialized sensory receptors are located deep within the dermis and subcutaneous tissue, responding to deep pressure and vibration. When pressure is applied, the Pacinian corpuscles become activated, sending signals to the nervous system to inform the brain about the sensory input. Their structure allows them to quickly adapt to changes in pressure, making them effective for detecting heavy touch stimuli.
