Pacinian corpuscle in dermis

A Pacinian corpuscle is a relatively large structure (up to a millimeter in diameter) located deep in dermis.  Each corpuscle resembles a tiny onion, with many concentric layers encapsulating a central nerve ending.  

Historical note:  An array of "Pacinian" corpuscles attached to digital nerves are shown at right, as reported from dissection by Vater nearly a century before Pacini.
