444 VESSELS OF THE PENIS. [SECT. 200. 



these glandules is supplied by small mucous follicles, like those above 

 described in the cervix vesicas. The epithelium of all these glands 

 is cylindrical, but in the ducts it merges into the tesselated variety. 

 The secretion is common mucus, which often collects in quantities 

 in enlargements of the gland-tubes. — Small fossse of the mucous 

 membrane, which are not uniformly present, have received the 

 name of lacunae Morgagnii; but in these I have not been able to 

 perceive anything of a glandular nature. — The fascia penis is a 

 membrane rich in fine elastic fibres, which invests the penis from 

 its root to the glans. At the root it is connected with the fascia 

 of the perineum and inguinal region, and also takes part in the 

 formation of the suspensory ligament of the penis, which proceeds 

 from the symphysis pubis to the dorsum of the organ, and abounds 

 in true elastic tissue. Externally, the fascia is continued uninter- 

 ruptedly into the skin. The integument of the penis, as far as 

 the free border of the prepuce, possesses the ordinary structure of 

 the cutis, though it is distinguished by its delicacy, and by the 

 occurrence of a layer of smooth muscular fibres beneath it, as far 

 as the prepuce. These fibres are a continuation of the tunica 

 dartos into the subcutaneous tissue of the penis, which is abundant 

 and wanting in fat. From the prepuce onwards, the integument 

 of the penis assumes more and more the nature of a mucous 

 membrane, it becomes much thinner, and no longer possesses hairs 

 and sudoriparous glands, though it has well-developed papillae. 

 On the glans, the membrane is intimately connected with the 

 spongy body, and is still provided with a soft epidermis, of 0*035"' 

 to o - 056'" in thickness (see § 44, fig. 40, 4). The sebaceous glands 

 in this situation, Avhich form the preputial sebaceous matter, are 

 peculiar in their characters, and are named glandula Tysoniance. 



The arteries of the penis arise from the pudic, and present no 

 peculiarities, except in their distribution to the corpora cavernosa. 

 These bodies receive their supply in the main from the deep arteries 

 of the penis, as well as a few small branches from the dorsal artery. 

 The larger arterial trunks run close to the septum, and are sur- 

 rounded by a sheath of connective tissue, connected with the trabe- 

 cular network. Giving off a small branch to the bulbs of the 

 corpora cavernosa, these vessels are directed forwards, distributing 

 numerous branches to the spongy tissue. These branches run in 

 a tortuous manner in the substance of the trabecule, occasionally 

 anastomosing, and divide, until they become capillaries of 0006"' 

 to 001" in diameter, which open directly into the venous spaces, 

 without forming a capillary network. The tortuous direction of the
