Photomicrograph of human bulbourethral gland. This photomicrograph shows a H&E-stained section of the compound tubuloalveolar bulbourethral gland. The epithelium consists of columnar mucus-secreting cells. The nuclei are displaced to the base of the cells by the accumulated secretory material that they contain. The cytoplasm has an appearance similar to typical mucus-secreting cells. Note several ducts (D) lined by a simple columnar epithelium. The ducts will merge to form a single excretory duct. In some sites the ducts contain mucus-secreting cells {arrows). X40.

The skin of the penis is thin and loosely attached to the underlying loose connective tissue except at the glans, where it is very thin and tightly attached. The skin of the glans is so thin that blood within its large, muscular anastomosing veins that drain the corpus spongiosum may give it a bluish color. There is no adipose tissue in the subcutaneous tissue. There is, however, a thin layer of smooth muscle that is continuous with the dartos layer of the scrotum. In uncircumcised males, the glans is covered with a fold of skin, the prepuce, which resembles a mucous membrane on its inner aspect. Numerous sebaceous glands are present in the skin of the penis just proximal to the glans.

The penis is innervated by somatic, sympathetic, and parasympathetic nerves. Many sensory nerve endings are distributed throughout the tissue of the penis, and sympathetic and parasympathetic visceral motor fibers innervate the smooth muscle of the trabeculae of the tunica albu-ginea and the blood vessels. Both sensory and visceral motor fibers play essential roles in erectile and ejaculatory responses.

ing and criss-crossing the corpus cavernosum. Irregular smooth muscle bundles are observed frequently as "suben-dothelial cushions" surrounding irregular vascular spaces (Fig. 21.31). The interstitial connective tissue contains many nerve endings and lymphatic vessels. The vascular spaces increase in size and rigidity by filling with blood, principally derived from the helicine arteries. These arteries dilate during erection (see box) to increase the blood flow to the penis. An arteriovenous (AV) anastomosis exists between the deep artery of the penis and the peripheral venous system.
