  • Title: Sensory nerve endings in the penis in green monkey (Cercopithecus aethiops sabaeus).
    Author: Malinovský L, Sommerová J.
    Journal: Z Mikrosk Anat Forsch; 1977; 91(1):94-104. PubMed ID: 417480.
    Abstract:
    The authors examined the sensory innervation of the skin in the penis in green monkey in four adult individuals both in the light and in the elctron microscope. They found 3 kings of nerve endings. The free nerve endings were the most frequently occurring kind of nerve endings in the superficial layers of the corium--altogether 6,444 in number. The second kind of sensory nerve endings is represented by the glomerular endings out of which 96 per cent were found in the papillae. The typical Meissner's endings were observed in the light microscopy only rarely. Deeper in the corium the authors also found single simple sensory corpuscles and Pacinian corpuscles. Studying the ultrastructure the authors found in the papillae of the corium 4 types of glomerular endings: quite simple glomerular endings with irregularly arranged Schwann cells, larger and more complicated glomerular endings having a thicker capsule, endings with lamellar system around the terminals and typical Meissner's endings. In the epidermis the authors observed naked axons which passed in the spaces among the epidermal cells. They contained an accumulation of mitochondria. In the basal cell layer of the epidermis there was a small amount of Langerhans cells.
