The third zone, or zone III, comprises the distal head and all the body. Histochemical localization of carbonic anhydrase in the testis and epididymis of the boar. Maturation, transport and fate of spermatozoa in the epididymis. Initial segment zone I. Regional histology and fine structure of the epididymal duct in the golden hamster Mesocricetus auratus. Note the stereocilia s and myoepithelial cells arrowheads.
Structure and function of the epithelium lining the ductuli efferentes; ductus epididymis and ductus deferens in the rat. The relative number of B and A cells is less frequent than in previous histological zones, and none peculiar features in both cells were seen, comparatively to those in other zones. The structure and function of the epididymis.
The few B cells found, contained an elongated nucleus parallel to the basal lamina. The physiology of reproduction. Along the five regions in dog epididymidis, are found columnar cells and basal cells.
The entire epididymal duct has a similar histological appearance, showing a pseudostratified epithelial lining, with stereocilia, covered by a myo-connective tissue sheath. 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.
An ihstologia study reveals the expression patterns of several cytokeratins, vimentin and desmin in the epididymis of the dog WAKUI et al. The histology of the rat epididymis. Fully exposed epididymis epixidimo the dog. The epididymis of the dog, based on morphological differences, reveals five distinct and continuous zone in the duct.
Ultrastructural differences in efferent ducts and several regions of the epididymis of the hamster. Table I – Morphological comparisons between different zones of the epididymis in the dog Morphological features.
The luminal diameter is The cell boundaries are indistinct, and a large number of long stereocilia projects from the apical cell surfaces to the lumen. Histological observations of the reproductive organs of the male dog from birth to sexual maturity.
These cells are arranged in a distinct layer, disposed immediately over the basal lamina. Each zone can be readly distinguished on the basis of its own duct morphological characteristics.
From the average values for each animal and its distinct epididymal zones, arithmetic means and s. They are tall cells, which extend from the basal lamina to the lumen. Functional relationship of the mammalian testis and epididymis. Note the anatomical regions: Morphology of the bovine epididymis.
On the regional histology and cytochemistry of the epididymis in the rabbits. Zur Struktur und Bedeutung der Epithelien immenschliechen Ductus epididymis. The epithelium contained all the cell types noticed. B cells are seen in great number with ovoid nuclei and evident nucleoli.
The basal B cells lie next to histoloiga basal lamina, and do not reach the tubular lumen. New York, Raven Press, Eipdidimo the principal papical a and basal b cells, and the stroma periductal rose.

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.
