WebMechanism. Pacinian corpuscles are responsible for detecting pressure and vibration stimuli. Any pressure or change in pressure is detected by the change in the position or shape of the lamella of Pacinian corpuscles. When pressure is applied to the skin, the lamella of Pacinian corpuscles gets deformed. WebJun 19, 2024 · To better understand their function, the researchers studied Meissner corpuscles in mice, which express Meissner corpuscles in their fingertips and palms. The work involved studying the organs up ...
