Fig. 63. — Drawings of the male genital system. A. Ventral view. The urethra 

 is completely straightened. The left corpus cavernosum penis and bulbocavernosus 

 muscle (right side of the drawing) are dissected, to show the urethral diverticulum, and 

 the bulbo-urethral gland. On the right side (left side of the drawing) these structures 

 are in normal position. The preputial sack is cut open. (X2M.) B. Dorsal view 

 of the cephalic end of the male urethra. {X2%.)
