EPIDIDIMO HISTOLOGIA PDF

Mezitaur The B cells are characterized by presence of nuclei of different shapes. Maturation of spermatozoa in the rabbit. Morphology of the bovine epididymis. Histochemical localization of carbonic anhydrase in the testis and epididymis of the boar. The A cells had a slender shape, and are characterized by a wide cytoplasmic apical part, a narrow body and a more apically located nucleus, comparatively to P cells morphology. Histologia aparato reprodutor epididimo The epididymis of epidiximo dog, based on morphological differences, reveals five distinct and continuous zone in the duct.

JoJogore Several histological features differentiate the zone V from the other epididymal zones, in the dog. HAMILTON reported that epididymis is a dynamic structure of the seminal pathway, and its complex morphophysiology does not agree with the concept that epididymis would have merely a passive influence on sperm physiology. Regional histology and fine structure of the epididymal duct in the golden hamster Mesocricetus auratus.

The histology of the rat epididymis. Epithelium of zone IV showing p and b cells. Epithelium of zone II showing p, a, and b cells, stereocilia s and stroma periductal rose.

B cells are seen in great number with ovoid nuclei and evident nucleoli. A light microscope and ultrastructural study. The epididymis of the dog, based on morphological differences, reveals five distinct and continuous zone in the duct. On the regional histology and cytochemistry of the epididymis in the rabbits. The luminal diameter is Note the anatomical regions: The muscle coat surrounding the epididymal duct in zone IV Figs.

Each zone can be readly distinguished on the basis of its own duct morphological characteristics. Maturation, transport and fate of spermatozoa in the epididymis.

The irregular lumen of the ductus have a diameter of It is observed zone I or initial segment and zone II, both of them localized into the head. The P cells are observed in all the five zones, of the epididymal duct. The fourth and fifth zones zones IV and Vare restricted to the epididymal tail, localized into the proximal and distal Cauda epididymidis, respectively. The A cells are fewer in number than the other cell types, and can be distinguished from P cells by their hietologia globlet shape, and apically located nuclei.

Histochemical localization of glycosidases in dog epididymis. Some features distinguished the epithelial lining of zone III. Functional relationship of the mammalian testis and epididymis. Zur Histotopik von Hydrolasen in Nebenhoden des Hundes. Ultrastructural differences in efferent ducts and several regions of the epididymis of the hamster.

A light microscope study. The zone I or initial segmentis characterized by an irregular and tall epithelium The luminal diameter has average of On the regional histology of uistologia ductus epididymis in the buffalo Bubalus bubalis. Histologia aparato reprodutor epididimo The fourth and fifth zones zones IV and Vare restricted to the tail, localized into the proximal and distal Cauda epididymidis, respectively.

The epithelial lining measures.

Sagar Thus, the purpose of this study is to describe morphologically epididijo regional histology of the ductus epididymidis in the dog, to provide a detailed structural baseline for specific studies of functional zonation in the epididymis of the dog, or, to comparate to other mammals. Also, it should be noted that transition between the zones is gradual, not abrupt. A cells, with round to ovoid nuclei, are scarcely found, and B cells are similar to those of preceeding zones. The epithelial lining measures Stellate lumen stars of the ductal sections in the zone III. The few B cells found, contained an elongated nucleus parallel to the basal lamina. Several histological features differentiate the zone V from the other epididymal zones, in the dog. These cells are arranged in a hiztologia layer, disposed immediately over the basal lamina.
