What is pacinian corspuscles?

Pacinian corpuscles are specialized mechanoreceptors located in the skin and other tissues, primarily responsible for detecting deep pressure and vibration. They are large, onion-shaped structures composed of concentric layers of connective tissue surrounding a nerve ending. When pressure is applied, these corpuscles rapidly adapt to the stimulus, providing the sensation of pressure changes. They play a crucial role in the tactile sensing system, contributing to our ability to perceive fine details and vibrations.
