a.1.(Anat.) Of, pertaining to, or discovered by, Filippo Pacini (1812-1883), an Italian physician of the 19th century.
Pacinian corpuscles
small oval bodies terminating some of the minute branches of the sensory nerves in the skin of the fingers, mesentery, integument and other parts of the body; the corpuscula lamellosa; called also Vater's corpuscles and Vater-Pacini corpuscles. They are sensitive to pressure, and supposed to be tactile organs.

Anatomy and physiology teach that feedback to the central nervous system comes largely from Golgi tendon organs, Pacinian corpuscles, and Ruffini nerve endings.
(2) FA mechanoreceptors can be divided into Meissner corpuscles and Pacinian corpuscles, being the first one related to low (30 Hz) and the later one to high (200 Hz) vibration frequencies.
Basic neurophysiological studies have shown that vibration can alter sensory and motor function by mostly activating the primary spindle endings, although secondary spindle endings, such as Golgi tendon organs, Pacinian, and Meissner corpuscles can also be activated [1].
In the dermis, there are Ruffini endings and Pacinian corpuscles in a glabrous (or hairless) skin, whereas there is a complex combination of mechanoreceptors and their associated nerves and hair follicle receptors in a hairy skin [23, 24].
