The prostate gland contains glandular acini that vary in size with wide and irregular lumina. The acini protrude into the connective tissue folds and secrete proteinaceous fluids that sometimes form prostatic concretions. The glandular epithelium is simple columnar or pseudostratified. The fibromuscular stroma is a characteristic feature of the prostate gland, containing smooth muscle bundles and connective tissue fibers that blend throughout the gland.

6. Bulbourethral gland:
⚫Compound tubulo-alveolar gland in bull, stallion and
ram, compound tubular gland in boar, cat and bucks
and absent in dogs.
⚫Glandular epithelium is simple columnar with
occasional basal cells.
⚫The collecting duct has simple cuboidal to columnar
epithelium.
⚫The intraglandular duct has pseudostratified columnar
epithelium.
⚫The bulbourethral duct is lined by transitional
epithelium.
⚫The gland is covered by fibro elastic capsule containing
striated muscle.
