  • Title: Intraperineural localization of lamellated sensory corpuscles in the skin and oral mucosae of the adult cat and miniature pig.

    Journal: J Neurocytol; 1989 Feb; 18(1):61-9. PubMed ID: 2468743.
    Abstract:
    Lamellated sensory corpuscles in the perioral tissues of the adult cat and the adult miniature pig were studied by light and electron microscopy. In the cat lip, over half of the lamellated corpuscles existed in an aggregate form associated with other nerve elements and blood capillaries in peripheral nerve swellings, while the remainder existed in an isolated form. Conversely, almost all the lamellated corpuscles in the miniature pig existed in an aggregate form in nerve swellings. Most of the intraperineural lamellated corpuscles showed ultrastructural characteristics of simple corpuscles. However, some of the intraperineural lamellated corpuscles exhibited interlaced arrangements of tortuous axon terminals and cytoplasmic lamellae resembling the arrangement in Meissner corpuscles. Immunohistochemical staining using anti-neuron specific enolase also revealed the presence of intraperineural, Meissner-like corpuscles in the cat lip. This study indicates that intraperineural localization of lamellated corpuscles is common in carnivora and artiodactyla and that the intraperineural lamellated corpuscles are heterogeneous in their ultrastructural pattern.
