Pacinian corpuscle
Quick Summary
The Pacinian corpuscle is a pressure-sensitive mechanoreceptor that terminates sensory nerve fibers, primarily found in the skin. It is an oval-shaped, encapsulated structure, about one millimeter in length, with a lamellated appearance similar to an onion.12
These receptors are located deep within the dermis and are classified as "rapidly adapting" mechanoreceptors, meaning they respond to specific stimuli like pressure and vibration. The Pacinian corpuscle is named after Filippo Pacini, an Italian anatomist.21
