abstract
The present work was carried out to investigate the histological and histometrical structure of the vesicular gland in the ram during non-breeding seasons. Twenty adult rams have brought from Al-kut slaughter house during the period from February to March and July to August 2017. The vesicular gland was compound tubulo alveolar gland divided into lobes and lobules and surrounded with dense connective tissue capsules. The gland had folded mucosa lined by pseudo stratified columnar epithelium rested on thin lamina propria-submucosa, followed by smooth muscle fibers of muscularis and adventitia. The glandular secretory units lined with sample columnar-pseudo stratified columnar epithelium showed little the secretory activities. The histometrical result showed low mean values for the diameter glandular acini, height and the width epithelial cells of acini were 44.23±1.34, 12.26±1.11 and 4.54± 0.92 respectively. Also the diameter of lumen of ducts and the height of epithelial cells were 35.86±1.21 and 10.23±1.33 respectively.
