Morphological Study of the Cervical Salivary Glands in the Nine-Banded Armadillo International Journal of Morphology
Schimming,Bruno Cesar.
The cervical salivary glands of the armadillo Dasypus novemcinctus was examined by light microscopy. These glands are situated on either side of the neck, divide in lobes and show a presence of a salivary bladder, associated with the main ducts of the gland. This gland is histologically a typical mixed glands, containing both mucous and serous elements, with mucous acini as the predominant secretory unit. The bladder itself is composed of a wall made up of pseudostratified epithelium, skeletal muscle and connective tissue. In general, the morphology of the cervical salivary glands appears similar to that described in other species of the mammals.

Zinc Iodide-Osmium Tetroxide (ZIO) Reactive Golgi Apparatus in the Principal Cells of Dog Epididymal Epithelium International Journal of Morphology
Schimming,Bruno Cesar; Vicentini,Carlos Alberto.
The cisternae of the Golgi apparatus of dog epididymal principal cells were labeled by the zinc iodide-osmium tetroxide method (ZIO). These cisternae were observed in the supranuclear region of the cytoplasm of the epididymal principal cells. Abundant endoplasmic reticulum cisternae, multivesicular bodies, mitochondria, lysosomes and vesicular elements of variable size were also found in this region, all associated with the sacks of the well-developed Golgi apparatus. The use of the ZIO method facilitates the observation and identification of the cisternae of the Golgi apparatus, thus permitting a correlation between structure and function in the so-called Golgi area. These ultrastructural characteristics support the secretory role of epididymal principal...

Morphological Features of the Apical Region in the Principal Cells of Mongrel Dog Epididymis International Journal of Morphology
Schimming,Bruno Cesar; Vicentini,Carlos Alberto.
The epithelial principal cells are the predominant cell type of the epididymis. These cells have been shown to be both secretory and endocytic cells. The apical region of the cytoplasm of principal cells in the mongrel dog are located close to the cell apex and tubular lumen, and shown microvilli at the luminal border and present a endocytic apparatus, that consists of coated pits and vesicles, endosomes of varying size, multivesicular bodies, and lysosomes. The endosomes, multivesicular bodies and lysosomes contained the electron-dense patches. These results suggest that principal cells of the epididymis in the dog as possess a highly developed endocytic apparatus play a role in endocytosis. These cells function are similarly to the related in other...

Observações morfológicas no ducto epididimário do cão Braz. J. Vet. Res. Anim. Sci.
Schimming,Bruno Cesar; Vicentini,Carlos Alberto; Tirapelli,Luís Fernando; Tirapelli,Daniela Pretti da Cunha.
O ducto epididimário, no cão, acha-se revestido por epitélio colunar pseudoestratificado, com população celular constituída por células principais, basais e apicais, presentes em todas as regiões. Este epitélio é circundado pelo estroma peritubular. O epitélio do segmento inicial epididimário possui a maior altura, que diminui progressivamente em direção à cauda epididimária. Ocorre um aumento progressivo do lúmen tubular através das diferentes regiões, sendo maior na região da cauda epididimária, configurando um local de estocagem de espermatozóides.
