Arrector Pili - because it does not have sensory detection.
MECHANOCEPTOR
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.
Meissner's corpuscles; pain and touch receptors, Pacinian corpuscles; pressure receptors, hair follicle receptors; light touch receptors, Rufini's corpuscles; respond to deep pressurethat recieve the stimulus
The Pacinian corpuscle responds to "mechanical" pressure i.e. touch.
pacinian corpuscle
Pacinian corpuscle is sensitive to deep pressure.

MECHANOCEPTOR

The pacinian corpuscle is present in the dermis layer of the skin. Its function is to detect deep pressure and vibration.
There are four different types of receptors in the skin. There are merkel receptors, meissner corpuscles, ruffini cylinders and pacinian corpuscles.
Inhibitory proprioceptors
It's the encapsulated endings- nerves that are found in the skin and joint capsules (end bulb of Krause, Ruffini corpuscles, Meissner's corpuscles, Pacinian corpuscles); skeletal muscle (neuromuscular spindles); muscle-tendon junctions (Golgi tendon organ)
Sensory receptors in the dermis include: free nerve endings, pacinian corpuscles, and hair follicle receptors The mechanoreceptors of the skin are the meissner's corpuscles (which respond to light touch), the pacinian corpuscles (deeper in the dermis and respond to pressure), and the merkel's disks (closely related to the merkel's cells located in the epidermis and respond to light touch). The nociceptors are pain receptors that recognize hot, cold, and pain.

Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion. They are responsible for detecting sensations like touch, pressure, vibration, and proprioception. Examples of mechanoreceptors include Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and hair cells in the inner ear.
