THE VULVA 459 



Each cord is composed of the spermatic artery, artery of 

 the vas deferens, and cremasteric artery, the spermatic veins 

 from the back of the testis, which receive the veins from the 

 epididymis to form the pampiniform plexus, a number of 

 large lymphatics, and the spermatic pjexus of the sympathetic, 

 together with the vas deferens, the layers of fascia which cover 

 the testicle, and the remains of the peritoneal testicular process. 



The inguinal canal (see p. 189 for description) is bounded 

 behind by the fascia transversalis and the conjoined tendon; 

 in front by the transversalis and internal oblique above, and the 

 external oblique aponeurosis below; its floor is formed by the 

 curving back of Poupart's ligament; its roof by the arched 

 fibers of the internal oblique in apposition with the aponeurosis 

 of the external oblique. 



THE EXTERNAL ORGANS OF REPRODUCTION 



(FEMALE) 



THE VULVA 



The term vulva, or pudendum, includes the mons veneris and 

 labia, the nymphse and clitoris, the hymen or its remains, 

 the meatus urinarius, and the vaginal orifice. 



The mons veneris is a fatty cushion covering the front of 

 the pubes, and after puberty is plentifully supplied with hairs. 

 Below, it divides into the.two labia majora, which, diminishing 

 in size as they pass downward and backward, unite an inch 

 in front of the anus. The two extremities are joined, and form 

 the anterior and posterior commissures. Between the latter 

 and the anus is the perineum, and just within the posterior 

 commissure is a transverse fold, the fnenulum pudendi, or 

 fourchette. Between this fold and the posterior commissure 

 is a triangular space, the fossa navicularis. 



The nymphse, or labia minora, smaller than the above, 

 run from the middle of the labia majora upward to the clitoris, 

 each dividing into two folds, the upper pair of which join to 

 form a prepuce for that organ, and the lower two to form its 

 frenum. They are continuous externally with the labia majora, 

 internally with the vagina. The mons veneris is composed
