skin of the penis, and especially to the glans penis, where they 

 terminate in Meissner's corpuscles, Krause's spheric end-bulbs, 

 and genital corpuscles (Fig. 414). 



FIG. 413. Diagram of the arterial circulation of the penis : 1, corpus cavernosum, 

 with 1', its root ; 2, suspensory ligament ; 3, corpus spongiosum with 4, bulb ; 5, 

 glans ; 6, internal pudic artery ; 7, bulbo-urethral artery, with 7', its bulbar branch, 

 7", its anterior branch going to the frenum; 8, arteria cavernosa, with 8', its recur- 

 rent branch ; 9, dorsal artery ; 10, 10, its lateral branches ; 11, its termination in 

 the glans (Testut). 



Sensory nerves are distributed also to the verumontanum, in the 

 urethra, and the pleasurable sensations connected with coitus are 

 due to the excitation of the nerves here distributed, as well as 

 to those supplying the glans 

 penis. 



In addition to sensory 

 nerves there are also distrib- 

 uted to the penis e x c i t o r 

 nerves, nervi erigentes, which 

 are derived from the first and 

 second, and sometimes from 

 the third, sacral nerves ; they 

 are vasodilator nerves, and 

 have their origin in the sex- 

 ual center of the spinal cord. 



Genital Organs of the 

 Female. Ovary. The ova- 

 ries (Fig. 415), two in num- 

 ber, are attached to the pos- 

 terior surface of the broad 

 ligament, one on each side of 

 the uterus, with which they 

 are connected by the ova- 

 rian ligament, a fibromuscular 

 structure. They are covered by peritoneum, except at the hilum, 

 which is, however, somewhat modified, its mesothelial cells form- 

 ing the germinal epithelium (Fig. 416), the cells of which are
