405. The Eight Testicle and Epididymis, 



natural size. 



The two t e s t i c 1 e; s, Tcxtic.uli, the glands producing the semen, 

 are suspended in the scrotum by the spermatic cords. Each testis has an 

 ovoid form ; its upper end is directed forwards and outwards, its lower 

 end backwards and inwards. The Tunica albuyinea s. propria surrounds 

 the glandular structure of the testicle, and, at its posterior and upper 

 border is reflected into the interior of the gland, forming an incomplete 

 vertical septum called the Mediastinum A'.sV/.s- -s. Corpus lh'<jlimori. From this 

 septum numerous slender fibrous cords a. re given off, which pass to be 

 attached to the inner surface; of the Tunica albuyinea ; they join with 

 similar cords given off from the Tunica aHnu/inca to form spaces which 

 (inclose the separate lobules of the testis. Each lobule consists of from 

 2 5 c o 11 v o 1 u t e d t u b e s, the TnlmU. xenuiitfcri ; as those approach the 

 Corpus llHjliniori, they unite; with one; another and finally form the Kdc. 

 Hnllcri ; from this rete, 12- 19 stronger tubules, the Vsa cffcrcnt-ia, arise, 

 which perforate the Tunica albuginea beneath the: Glolms major of the 

 epididymis, in the convoluted canal of which they ultimately terminate.
