Pacinian Corpus, Pacinian corpuscles are structurally complex sensory receptors, encapsulating the endings of mechanosensory neurons in a distinctive onion-like INTRODUCTION Pacinian corpuscles (PCs, Corpuscula iamellosae, see Cauna and Mannan, 1958) come under the gross classification of primary mechanoreceptors (Davis, 1961): The threshold of Pacinian corpuscles increases considerably when the receptor is stimulated along the longitudinal axis. The investigation was initiated on the hypothesis previously suggested by one of us (II'inskii} that The Pacinian corpuscle (PC) is a dermal touch receptor responsible for transducing high{ frequency vibrations, making it a central biological component for haptic processing. It includes information about (i) the Pacinian corpuscles are rapidly adapting mechanoreceptor end-organs that detect transient touch and high-frequency vibration. The Pacinian corpuscle is a mechanoreceptor, which means it is a sensory receptor that responds to touch, pressure or vibration. Arterial twig, ending in capillaries, which form The Pacinian corpuscle is a highly sensitive mammalian sensor cell that exhibits a unique band-pass sensitivity to vibrations. Pacinian Corpuscles: The Inner Core The terminal glial cells of Pacinian corpuscles form the inner core, which lies between the axon and the intermediate layer. Pacinian corpuscles are the largest sensory receptor, visible to the naked eye, and usually localized in the palmar and plantar aponeurosis.
