Scanning electron microscopic observations on the eruption of primary teeth in the opossum.
Just prior to the emergence of the tooth into the oral cavity, a small circular crater forms in the gingival epithelium immediately above the crown. The craters appear to expand in diameter during eruption to accommodate the emerging crown of the tooth. The observations support the concept that the crown of the tooth does not actively push through and rupture the gingival epithelium, but rather...
متن کاملLight and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)
BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...
متن کاملHuman cardiac myosin: electron microscopic observations.
• Physicochemical studies on cardiac myosin of rabbits and dogs have shown that the myosin molecule is highly asymmetric, measuring about 1600 to 1800 A-' long and having a molecular weight of approximately SOO^OO." Electron micrographs of canine cardiac myosin have confirmed this general morphology, although the molecule appears to be several hundred angstroms shorter than the physicochemical ...
متن کاملScanning electron microscopic observations on human blood platelets and their alterations induced by thrombin.
Since the introduction of transmission electron microscopy in hematology, blood platelets have frequently been the subjects of investigation using shadow cast technique or ultrathin sections on account of their unique native (circulating) form and their behavior (aggregation) and transformation during hemostasis (for review see; JOHNSON et al. 1961, DAVID-FERREIRA 1964, MARCUS and ZUCKER 1965, ...
متن کاملTongue structure in the long-eared hedgehog (Hemiechinus auritus): A scanning electron microscopic study
The aim of this study was to investigate the dorsal surface of the long-eared hedgehog tongue using scanning electron microscopy. The tongue of the long-eared hedgehog is rectangular-shaped with an elongated body and a widened root and a marked deep median groove can be seen on its dorsal surface. A characteristic feature of the lingual root is presence of two huge laterally situated folds. The...
