It reaches the glans penis and anastomoses with the artery of the corpus cavernosum and the dorsal artery of the penis. This vessel is quite often absent. The artery of the corpus cavernosum (a. profunda penis), one of the terminal branches of the internal pudic, arises just after that vessel has perforated the superficial triangular ligament, and, quickly entering the crus penis obliquely, runs forward in the centre of the corpus cavernosum, to which its branches are distributed. Transversus peniin ?Superficial perineal artery. ?Superficial perineal nerve. Internal pudic nerve. Internal pudic artery. Fig. 476.—The superficial muscles and vessels of the perine The dorsal artery of the penis (a. dorsalis penis) ascends between the crus and pubic symphysis, and passes between the two layers of the suspensory ligament of the penis, and runs forward on the dorsum of the penis to the glans, where it divides into two branches which supply the glans and prepuce. On the dorsum of the penis it lies immediately beneath the integument, between the dorsal nerve and the deep dorsal vein, the former being on its outer side. It supplies the integ- ument and fibrous sheath of the corpus cavernosum, sending branches through the sheath to anastomose with the preceding vessel. The internal pudic artery in the female is smaller than in the male. Its origin and course are similar, and there is considerable analogy in the distribution of its branches. The superficial perineal artery supplies the labia pudendi; the artery of the bulb supplies the bulbi vestibuli and the erectile tissue of the vagina;
