Pacinian (lamellar ) corpuscle. Left: Schematic illustration of a lamellar corpuscle sectioned longitudinally. The axon (yellow) is surrounded immediately by lemmocytes, in turn surrounded by perineural epithelium. The red arrow points to a transection at the level indicated. Right: Transverse section through an actual Pacinian corpuscle. The axon (a, yellow) is surrounded immediately by neurolemmocytes (n), in turn surrounded by perineural epithelium (p).
