The objective of this work was to establish for the first time a complete three-dimensional model of the ovine oviductal mucosa. The oviducts of 15 cyclic ewes were examined combining the direct examination of the mucosa, by scanning electron microscopy (SEM) and histology, with the SEM observation of resin moulds of the oviductal lumen. Around the ostium abdominale, all longitudinal primary folds and wide secondary are seen to form cul-de-sacs, with their opening pointing in the ovarian direction ...

With 6 figures Summary The morphology of the stomach of Malayan pangolin, Manis javanica was studied at macroscopic, light microscopic, and scanning electron microscopic levels. The stomach of M. javanica was C‐shaped with short lesser curvature. At the oesophageal junction, the inner smooth muscle was thickened in the greater curvature side. The entire stomach was lined by a thick cornified stratified squamous epithelium, except at the duct orifices of glands and in the pyloric gland region. The ...

This study was carried out to record the detailed morphometric structure of the trachea in dogs using 15 female and four male healthy adult mongrel dogs. The diameter and thickness of each tracheal ring were measured, the number of tracheal rings varying from 36 to 45. All data were subjected to statistical analysis which was carried out on individual sections of the trachea, i.e. the cranial cervical, middle cervical, thoracic inlet and the intrathoracic tracheal regions, which consisted of 12, ...

Summary This study was a follow up to the study on the gross anatomy of the male agouti ( Dasyprocta leporina ) reproductive system. The seminal vesicles of the agouti are lobulated structures. The mean diameter of the large lumen is 883.6 ± 76.83 μm. The mucosa (24.1 ± 0.92 μm), which is lined by pseudo‐stratified columnar epithelium is thrown into folds, which often branch. The lamina muscularis mucosa is thin and is made of loose connective tissue containing blood vessels. The mucosa of the leaf‐like ...

Summary In MRL mice aged more than 1 year, but not in C57BL/6 mice, ovaries had grossly visible cysts presenting unilaterally or bilaterally. Postnatally, all MRL mice developed ovarian cysts by 8 months of age. Observations by light microscopy, including lectin histochemistry, indicated that the cysts sometimes included papillomatous tissues located at the hilar region and were similar to the rete ovarii system, but not to follicles. Two types of epithelial cells, ciliated and non‐ciliated, were ...

Summary The ultrastructure of the surface epithelia from the uterotubal junction (UTJ), and the adjacent tuba1 isthmic and endometrial regions, was studied in preovulatory oestrus gilts, either unmated or inseminated 12 h before with fresh boar semen. The simple columnar epithelium of the UTJ consisted of non‐ciliated (secretory) and ciliated cells. Secretory vesicles occurred in the secretory cells, especially in inseminated gilts. Lymphocytes, monocytes and macrophages were found dispersed basally ...

At one week, the whole epididymal duct had a simple low columnar epithelium. In the terminal segment the epithelium ecquired a structure similar to that in the adult epididymis at the age of about 6 weeks. Normal spermatozoa were not seen in the cauda epididymidis until the lambs were about 18 weeks ...

The analysis of the organs was made by histological methods and by macro and microscopic measurement techniques. The animals showed oviducts with macro and microscopically differentiable regions. Their mucosa showed primary branched folds in the ampullar sector. In the rest of the oviduct tract these folds ...

Although the results do not show very consistent morphological signs of secretory activity by the epithelium of these organs, lipidic droplets and lamellar granules present in mature males’ seminal vesicles and the vacuoles present in post‐vesicular vas deferens are probably secretion. Besides, the spermatozoa ...

Cell counting revealed that the average numbers per column of various types of germ cells do not show any significant differences among 5 fowls and between paired testes. The frequency of spermiogenic steps (numbered 1-8) was investigated ...

Summary A three‐dimensional model has not been clearly established for the porcine oviductal mucosa. The oviducts of 12 cyclic sows were examined by Scanning Electron Microscopy to study the structure and nature of the mucosal arrangement of the oviduct. Epithelial cyclic changes were also studied. The oviductal infundibulum is an asymmetric funnel‐shaped structure surrounding the ostium, in which a wide and a narrow side can be distinguished. The mucosa is more complex in the narrow side, showing ...

Permeability glycoprotein (P-gp) is a membrane-bound efflux pump that exports various substances out of the cell. Variations in P-gp expression play an important role in susceptibility to toxic substances, drug efficacy and disease risk. In the present study, the distribution of the MDR1-gene product P-gp was determined in normal tissues of domestic shorthair cats using immunohistochemistry. Two monoclonal antibodies C494 and C219 were used, recognizing a different epitope on the human P-gp molecule. ...

We examined the glandular chambers by SEM, TEM, ultrahistochemical and lectinhistochemical methods. The glandular epithelium is a high columnar epithelium with club‐shaped apical protrusions bearing short microvilli. The epithelium forms extensive folds which fill up most of the lumen of the glandular chambers. Proceeding to the placental labyrinth, the glandular chambers ...

The carpal organ of adult female wild swine is a sweat‐type gland which secretes an odorous substance. The gland consists of 5–7 lobes, each made up of lobules with convoluted glandular tubules. The gland secretion is transported in large excretory canals which empty from 5 to 7 clearly visible pores. An ultrastructural examination showed that the glandular tubules are made up of single‐layered epithelium with different types of cells. One type, with rather electron‐dense cytoplasm, is secretory ...

Morphological studies of the gastrointestinal tract of blue-and-yellow macaws (Ara ararauna) are scarce. In view of the paucity of information regarding the digestive tract of macaws, this study aims to describe the gross anatomical features (oesophagus to cloaca) as part of a broad study of the gastrointestinal tract (GIT) of these birds.

Koala mandibular (submandibular) glands are compound tubuloacinar glands, the secretory units of which consist only of serous cells. Intercellular canaliculi occur between the serous cells, which are continuous with a minute lumen that courses through the centre of each secretory unit. Intercalated ducts are abundant and join striated ducts, the latter being characterized by elaborate basolateral infoldings of the plasmalemma. Secretory granules within the serous cells fail to stain with either the ...
