Decalcified section of the pelvic region. (X30.) Bulbo-urethral glands.—The paired bulbo-urethral glands (glands of Cowper) are retort-shaped organs composed of tubulo-alveolar glands. The body is partially covered by the musculus bulbocavernosus, while the tail runs throughout the muscles and its duct enters into the cephalic wall of the urethral diverticulum (Fig. 73). The tail is an aggregation of small gland lobules covered by a connective tissue membrane. The body is surrounded by striated muscle fibers; inside this a very thin connective tissue membrane involves the gland and, projecting inward, forms the delicate inter-alveolar tissue. The tubules and alveoli are lined by tall columnar epithelial cells which have small, dark staining nuclei flattened against the bases of the cells. The cytoplasm stains pale blue with.
