  • Title: Catecholamine-containing cells of the taste buds in the tongue of the frog (Rana temporaria).
    Author: Krokhina EM, Esakov AI, Savushkina MA.
    Journal: Arch Anat Microsc Morphol Exp; 1975; 64(1):67-74. PubMed ID: 1082738.
    Abstract:
    In a study of the epithelial layer and taste buds of the tongue of the frog using fluorescence, peculiar dumb-bell shaped cells were found in the taste buds of fungiform papillae and these showed a highly-positive reaction to catecholamines. Adrenergic nerve fibres were detected in the vessels of the taste bud and in the epithelium of the tongue. Under conditions of catecholamine deficiency produced by preliminary reserpinization of frogs a decrease in specific fluorescence of the cells and the nerves was observed.
