A channel passes along the side facing the cloaca to the opening of the urinogenital sinus: this condition is usually retained throughout life in the case of the clitoris of the female, while in the male (and occasionally in the female also) the groove becomes closed to form a canal continuous with the urinogenital canal or urethra, which thus becomes considerably lengthened. In addition to the paired erectile corpora cavernosa there is a median corpus spongiosuin or corpus cavernosum urethrce in connection with the penis (Fig. 307): corpora cavernosa are also. CiiPju.
