. Cunningham's Text-book of anatomy. Anatomy. Glans penis Corpus cavernosum penis Corpus cavernosum urethra orpus cavernosum. Urethra Fig. 1019.—Transverse Section through the Body of the Penis. Urethra Fig. 1020.—A Longitudinal Section of the Terminal Portion of the Penis. is continued backwards to join the sheath of the conical end of the corpora cavernosa and ventrally it crives attachment to the frenulum of the prepuce. It imperfectly divides the erectile tissue of the glans into right and left portions, which, however, freely communicate dorsally From the septum, trabecular pass out in all directions into the tissue ot the glans. Loosely surrounding the corpora cavernosa penis and the corpus cavernosum uretnrse is a fibrous sheath containing numerous elastic tissue fibres. This sheath is termed the fascia penis, and reaches as far as the base of the glans, where it becomes fixed to the floor of the groove limited by the corona glandis. In its proximal part the sheath gives insertion to many of the fibres of the bulbo-cavernosus and ischio-cavernosus muscles. Superficial to the fascia penis is a layer of extremely lax areolar tissue, and more superficial still is a prolongation of the tunica dartos of the scrotum, covered by the delicate skin of the penis. Numerous sebaceous glands are present in the slnn, especially on the urethral aspect of the penis. In some mammals, such as the walrus, dog, bear, baboon, etc., a bone called the os penis is developed in the septum which intervenes between the corpora cavernosa penis. Vessels and Nerves of the Penis.—The penis receives its arterial supply from branches ot the internal pudendal artery. The erectile tissue of the corpora cavernosa penis is supplied ckieflv bv the deep arteries of the penis, while that of the corpus cavernosum urethras receives its arterial supply from the artery to the bulb. Branches of the dorsal artery of the penis piercing the fibrous coat of the corpora cavernosa penis furnish addition
