There are more touch and pressure receptors such as Meissner's corpuscles, Pacinian
corpuscles, Merkel's disks, and Ruffini's corpuscles under the skin of the palm than under the skin of the dorsal part of the hand.
The ACL also has a proprioceptive function, and it has been shown to contain several mechanoreceptors, including Pacinian
and Ruffini corpuscles.
Histopathology revealed proliferation of fibrous connective tissue accompanied with whorled structures Pacinian
bodies that showed no sign of malignancy.
Vibration excites Pacinian
corpuscles, and these receptors convey their information through gracile and cuneate fascicles to higher centers.
Somatosensory stimulation can be applied with a small vibrator systematically along the lateral surfaces of the fingers where Merkel disc and Pacinian
corpuscles are abundant (see Figure 1).

Many encapsulated endings found in fascia are mechanoreceptors that respond to mechanical pressure or deformation, and include Golgi receptors, Pacinian
corpuscles, and Ruffini's corpuscles.
On the other hand palmar skin is abundant in pacinian
corpuscles and sweat glands for optimal sensibility and to provide moisture respectively1.
Researchers found that mice lacking the proper version of a protein called c-Maf have deformed Pacinian
corpuscles, the vibration detectors that surround mouse bones (normal corpuscles shown here ill a mouse's leg).
When you stroke your fingers over a surface, its structure triggers high-frequency vibrations in the finger, to which specific touch receptors, the Pacinian
corpuscles and Merkel disk receptors respond to vibration and light touch (or pressure) , this result may suggest that the distribution of these two kinds of receptors is denser on the ventral forearm.
Neurophysio-logical recordings indicate that, when such fine textures strike on the finger pad skin, the fingerprint ridges vibrate and cause Pacinian
Corpuscles to respond, thus enabling the detection of the micro texture (Elias & Saucier, 2005).
