NaOH cell maceration/scanning electron microscopic studies on the connective tissue core in the incisive portion of the mouse hard palate. 1995

NaOH cell-maceration method was applied to the oral surface of the mouse hard palate to demonstrate the three-dimensional architecture of the connective tissue core (CTC) in the incisive portion. The CTC of the incisive papilla was inverted T-shaped, and was partially fused to that of the first antemolar ruga. Between the CTC of the incisive papilla and that of the first antemolar ruga, the incisive foramen opened in the shaped of crescent hiatus. Further, the round depressions, corresponding to the site of the taste buds, were situated exclusively in the anteromedial margin of the incisive foramen and in the oral aspect of the CTC of the incisive papilla close to the foramen. Such topographical relationship between the taste buds and the incisive foramen seems to be correlated to the discriminatory function of the taste buds. In the lateral sides of the incisive papilla, the connective tissue layer formed the conspicuous serrated ridges. It is suggested that the serrated ridges are interdigitated with the furrows in the basal surface of the epithelium, and act to prevent the epithelium from slipping during mastication.

UI MeSH Term Description Entries
D008297 Male Males
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY. Scanning Electron Microscopy,Electron Scanning Microscopy,Electron Microscopies, Scanning,Electron Microscopy, Scanning,Electron Scanning Microscopies,Microscopies, Electron Scanning,Microscopies, Scanning Electron,Microscopy, Electron Scanning,Microscopy, Scanning Electron,Scanning Electron Microscopies,Scanning Microscopies, Electron,Scanning Microscopy, Electron

D003238 Connective Tissue Tissue that supports and binds other tissues. It consists of CONNECTIVE TISSUE CELLS embedded in a large amount of EXTRACELLULAR MATRIX. Connective Tissues,Tissue, Connective,Tissues, Connective
D004846 Epithelial Attachment A wedge-shaped collar of epithelial cells which form the attachment of the gingiva to the tooth surface at the base of the gingival crevice. Epithelium, Junctional,Junctional Epithelium,Attachment, Epithelial,Attachments, Epithelial,Epithelial Attachments
D005260 Female Females
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001485 Basement Membrane A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers. Basal Lamina,Basement Lamina,Lamina Densa,Lamina Lucida,Lamina Reticularis,Basement Membranes,Densas, Lamina,Lamina, Basal,Lamina, Basement,Lucida, Lamina,Membrane, Basement,Membranes, Basement,Reticularis, Lamina
D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species. Species Specificities,Specificities, Species,Specificity, Species
D013649 Taste The ability to detect chemicals through gustatory receptors in the mouth, including those on the TONGUE; the PALATE; the PHARYNX; and the EPIGLOTTIS. Gustation,Taste Sense,Gustations,Sense, Taste,Senses, Taste,Taste Senses,Tastes
