The epididymis in the dog, reveals five distinct and continuous histological zones in the duct. 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.

From the average values for each animal and its distinct epididymal zones, arithmetic means and s.

Usually, their nuclei are histokogia and situated at the middle part of the cell but, because of the shortness of the P cells, nuclei rest near the basement membrane. P cells are also the most common epithelial cell type found in this zone.
