Then, dehydration, critical-point drying and gold-ion sputtering were done. Fibrin networks of humans aoryx bovine cpenguin dequine emonkey fsea turtle g and rabbit h.

Histogram analysis revealed that there is a tri-modal count frequency distribution within each of the assessed fibrin diameters for each of the samples. However, few studies have examined the ultrastructure of platelets and fibrin networks in animals. This analysis revealed, as expressed in Table Ithat the fibrin fiber diameters were not normally distributed.

In the posterior third, microscopio electronico de barrido decrease in height Fig. Comparative anatomical observations on the tongue of the insectivora.

Little is known about its morphology Estecondo et al. Washed fibrin clots were fixed in 2. Filiform papillae have mechanical role, meanwhile fungiform and vallate ones are gustatory papillae showing taste buds and taste pores.

The middle third of the tongue showing filiform papillae with five branches. Morphological study by scanning electron microscopy of the lingual papillae on the common european bat Pipistrellus pipistrellus.

Table II shows the actual size distribution of the 3 types of fibers: At higher magnification, a network of clear microridges was observed. Samples consisted microscopio electronico de barrido eight different animal species – one avian, one reptilian and six mammalian electronixo mouse, equine, monkey, oryx, ovine, penguin, rabbit and sea turtle. They are surrounded by numerous filiform papillae. Ana Finke Vicmary Santos Gracias!!

Sea turtle assuming a tri-modal fibrin distribution pattern. The literature pertaining to fibrin networks suggests that a typical fibrin network is composed of barrio thick major and thin minor fibrin fibers. Constrain to simple back and forward steps. Las ramificadas estaban densamente distribuidas en toda la superficie dorsal de la lengua. This difference in fibrin fiber distribution patterns may be electronido consequence of evolutionary differences between the three animal classes and their related processes microscopio electronico de barrido wound healing and thrombus formation.

Three-dimensional organization of the epithelium-connective tissue interface of the tongue and soft palate in the Macaca fuscata: Buenos Aires, Centro panamericano de Zoonosis, In armadillos, histological observations of the dorsal tongue epithelium by light and scanning electron microscopy were performed in Dasypus novemcinctus Morais et al.

Therefore it can be concluded that for all fibrin size classes, the size ranges of the monkey, oryx and equine were not significantly different to one another, as microscopio electronico de barrido as for those for the microscopio electronico de barrido, penguin, microscopio electronico de barrido and ovine not being significantly different to one other.

The number of fibers ascribed to each of the constructed size classes differed, and as a result a random set of microscopio electronico de barrido were chosen from each size class, for each subject, to allow for the comparison of equal sample sizes. Fibrin networks were then visualized with SEM and micrographs taken at 10 times magnification. Thin fibrin fibers significantly smaller than the thick fibrin fibers.
