  • Title: [Differentiation of tactile corpuscles (Merkel's) in the beak of Coturnix coturnix quail during ontogeny].
    Author: Boĭchuk NV, Chelyshev IuA.
    Journal: Arkh Anat Gistol Embriol; 1987 Nov; 93(11):55-61. PubMed ID: 3446099.
    Abstract:
    Succession of the Merkel's corpuscles appearance and the nervous fibers connected with them in the germ of the beak has been studied by means of light (silver nitrate impregnation) and electron microscopic techniques. Appearance of the Merkel's corpuscles in the subepithelial connective tissue is preceded by sprouting of nervous fibers into the area. From the very beginning of their differentiation the tactile corpuscles are in contact with nervous terminals. Sensory innervation is a necessary condition for differentiation of the Merkel's corpuscles and tactile bodies in the bird quail.
