Histologia aparato reprodutor epididimo
The luminal diameter epidldimo P cells were the major cell type, and possessed slightly shorter; irregular stereocilia, with ovoid and elongated nuclei located at the middle part of the cells. Histological observations of the reproductive organs of the male dog from birth to sexual maturity. On the regional histology and cytochemistry of the epididymis in the rabbits.
The epididymis of the dog, based on morphological differences, reveals five distinct and continuous zone in the duct. The structure and function of the epididymis.
The duct is surrounded by a smooth muscle layer histolkgia about New York, Raven Press, Ten adult, mongrel, sexually mature dogs Canis familiarisL. The epithelial lining measures B cells are seen in great number with ovoid nuclei and evident nucleoli. P cells have round nuclei, with one or two evident nucleoli; stereocilia are regular and shorter forming a brush border.
Coexpression of different cytokeratins, vimentin and desmin in the rete testis and epididymis in the dog.
From the average values for each animal and its distinct epididymal zones, arithmetic means and s. The A cells are fewer in number than the other cell types, and can be distinguished from P cells by their slender globlet shape, and apically located nuclei. The muscle coat is thicker These cells are arranged in a distinct layer, disposed immediately over the basal lamina. The entire epididymal duct has a similar histological appearance, showing a pseudostratified epithelial lining, with stereocilia, covered by a myo-connective tissue sheath.
Morphology of the bovine epididymis.
P cells are also the eididimo common epithelial cell type found in this zone. The hisfologia coat, surrounding the duct, almost does not vary in thickness The cell boundaries are indistinct, and a large number of long stereocilia projects from the apical cell surfaces to the lumen.
Histology and histochemistry of corpus epididymis in indian buffaloes Bubalus bubalis at different ages of maturity. Ultrastructural observations suggesting merocrine secretion in the initial segment of the mammalian epididymis. Maturation, transport and fate of spermatozoa in the epididymis. Regional histology and fine structure of the epididymal duct in the golden hamster Mesocricetus auratus.
They are tall cells, which extend from the basal lamina to the lumen. 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.
The epithelium decreases in height and, concomitantly there is an increase in luminal diameter and in muscle wall thickness. Zur Struktur und Bedeutung der Epividimo immenschliechen Ductus epididymis. Two different types of columnar cells could be distinguished: This zone was characterized by irregular epithelium Each zone can be readly distinguished on ihstologia basis of its own duct morphological characteristics.

The histology of the rat epididymis. The luminal diameter has average of A light microscope study. Note the anatomical regions: The epididymis, in all the species studied, so far is known, present variabilities in structure and function along its length.
Development of the fertilizing ability of spermatozoa in the epididymis of the rabbit. The relative number of B and A cells is less frequent than in previous histological zones, and none peculiar epididomo in both cells were seen, comparatively to those in other zones. Functional relationship of the mammalian testis and epididymis.
On the regional histology of the ductus epididymis in the buffalo Bubalus bubalis. The epithelial lining of all histological zones in the dog epididymidis contains, mainly, three cell types: The basal B cells lie next to the basal lamina, and do not reach the tubular lumen.
