Pacinian corpuscle refers to a receptor with a distinctive elliptical shape associated with RA2 mechanoreceptors. It transmits pressure to the nerve fiber inside it only at the beginning or end of a pressure stimulus, and is responsible for our perception of vibration and fine textures that are perceived when moving the fingers over a surface. Pacinian corpuscles are proprioceptor sensitive to pressure and vibration found in the subcutaneous, submucosa, subserous tissues around joints, external genitals, and mammary glands.
