Encapsulated mechanoreceptors {pacinian corpuscle}, 1 to 2 mm diameter, detect deep pressure. Pacinian corpuscles are fast-adapting, have large receptive fields, and are in body, joint, genital, and mammary-gland hairy-skin and glabrous-skin deep layers.
Pacinian corpuscles respond to vibration with maximum sensitivity at 200 to 300 Hz. Range is 20 to 1500 Hz. Pacinian corpuscles can detect movements smaller than one micrometer. Pacinian corpuscles have lamellae, which act as high-pass filters to prevent steadily maintained pressure from making signals. Pacinian corpuscles send to myelinated dorsal-root neuron fibers.
