The tongue of the mudpuppy, Necturus maculosus, appears smooth and without any papillae. Farbman and Yonkers (1971) reported that the tongue contains round elevations or eminences, each with a single, large taste bud. Furthermore, their light micrographs, made of sectioned tissue, showed that the tips of the buds are flush to the lingual surface. In contrast, the mammalian taste buds lie below the epithelium of the lingual papillae and contact the surface only by way of a narrow taste pore. We undertook SEM studies to confirm this morphology, one which would be advantageous for later neurophysiological studies involving the stimulation of individual taste buds and microelectrode recording from taste bud cells.Figure 1 shows two adjacent eminences from the mudpuppy's distal tongue. The taste bud shows as a surface irregularity, centered at the top of each mound. Their dimensions and general distribution correspond to those reported by Farbman and Yonkers.

Taste Bud Cells

It is well known that taste buds are dependent on an intact nerve supply, and when experimentally denervated they degenerate and disappear (von Vintschgau & Honigschmied, 1877; von Vintschgau, 1880; Griffini, 1887; Meyer, 1897; Olmsted, 1920a, b, 1921, 1922; May, 1925; Whiteside, 1927; Torrey, 1934, 1936; Wagner, 1953; Guth, 1957, 1958, 1963; Beidler, 1962, 1963). Olmsted (1920b) has suggested that the degenerating taste bud cells are cleared away by macrophages invading the epithelium; Guth (1957, 1958, 1963) has demonstrated sloughing of degenerating taste buds from the epithelial surface, and others believe that taste bud cells dedifferentiate to become lining epithelium (Meyer, 1897; Wagner, 1953). Because of this disagreement and because recent evidence for cell turnover in taste buds has indicated that cell death and replacement is a normal occurrence (Beidler, 1962, 1963; DeLorenzo, 1963; Beidler & Smallman, 1965), it is pertinent to study the fine structure of degenerating taste buds in the hope of elucidating the process by which taste bud cells and nerve terminals degenerate.

Platelet adhesion initiates platelet aggregation and is an important component of the hemostatic process. Since the development of a new form of collagen as a topical hemostatic agent is of both basic and clinical interest, an ultrastructural and hematologic study of the interaction of platelets with the microcrystalline collagen preparation was undertaken.In this study, whole blood anticoagulated with EDTA was used in order to inhibit aggregation and permit study of platelet adhesion to collagen as an isolated event. The microcrystalline collagen was prepared from bovine dermal corium; milling was with sharp blades. The preparation consists of partial hydrochloric acid amine collagen salts and retains much of the fibrillar morphology of native collagen.
