A bulbourethral gland, also called a Cowper gland for English anatomist William Cowper, is one of two small exocrine glands in the reproductive system of many male mammals (of all domesticated animals, they are only absent in the dog).They are homologous to Bartholin's glands in females.he bulbourethral glands are compound tubulo-alveolar glands, each approximately the size of a pea in humans. In chimpanzees, they are not visible during dissection, but can be found on microscopic examination. In boars, they are up to 18 cm long and 5 cm in diameter.
Sweat glands are duct glands found in the skin and responsible for the secretion of sweat, which are watery in nature. The duct of the gland is opened at the skin surface by minute pore. There are two types of sweat glands; eccrine sweat glands and apocrine sweat glands. Eccrine sweat glands secrete thin sweat and are not associated with hairs. Eccrine secretions are crucial for thermo-regulation of animals.
