The luminal diameter has average of Note the stereocilia s and myoepithelial cells arrowheads. Along the five regions in dog epididymidis, are found columnar cells and basal cells. The adluminal stereocilia are long.


Usually, their nuclei are round and situated at the middle part of the cell but, because of the shortness of the P cells, nuclei rest near the basement membrane. Histology and histochemistry of corpus epididymis in indian buffaloes Bubalus bubalis at different ages of maturity.

P cells have round nuclei, with one or two evident nucleoli; stereocilia are regular and shorter forming a brush border. The samples, collected from the anatomical regions of the epididymides, were fixed in Bouin’s fluid, dehydrated and embedded in paraffin.

The spididimo still are regular and shorter, forming a brush border. A cells are scarce and presented the same morphology, as described later. The muscle coat surrounding the epididymal duct in zone IV Figs.

A cells, with round to ovoid nuclei, are scarcely found, and B cells are similar to those of preceeding zones. New York, Raven Press, Studies on the regional histology and histologla of the ductus epididymis in stallions, rams and bulls. The duct is surrounded by a smooth muscle layer of about The basal B cells lie next to the epididiom lamina, and do not reach the tubular lumen. The muscle coat is thicker Morphology of the bovine epididymis. The cell boundaries are indistinct, and a large number of long stereocilia projects from the apical cell surfaces to the lumen.

Ultrastructural observations suggesting merocrine secretion in the initial segment of the mammalian epididymis. An immunocytochemical study reveals the expression patterns of several cytokeratins, vimentin and desmin in the epididymis of the dog WAKUI et al.

The mammalian epididymidis is an important segment of the excurrent duct system of the testis, that performs a variety of functions. Regional histology of the epididymis of the dog.

Maturation, transport and fate of spermatozoa in the epididymis. The few B cells found, contained an elongated nucleus parallel to the basal lamina.


Thus, the zone V was characterized by lower epithelium, greater luminal diameter, greater sperm concentration, denser and shorter stereocilia, and a thicker smooth-muscle wall, comparatively to other epididymal zones. A morphologic study of the ductus of the epididymis of Sus domesticus. The epithelial height of zone II is somewhat lower than those of zone I The epididymis, in all the species studied, so far is known, present variabilities in structure and function along its length.

The B cells are characterized by presence of nuclei of different shapes. The physiology of reproduction.
