406. Testis and Epididymis, Injected with Mercury. 



The epididymis lies at the posterior border of the testis ; it 

 has an upper enlarged extremity, the head, or Globus major, and a lower 

 pointed extremity, the tail, or Globus minor, which is continued into 

 the tyas .deferens. The lobules, which are formed by the convolutions of 

 the y 'feeminiferous tubules coming from the testis, are of pyramidal form 

 ;ni(l are called Coni vasculosi Halleri. By the union of these coni a single 

 ca^al or duct is formed, the intervening and subsequent convolutions 

 of which constitute the epididymis itself. This single canal gradually 

 becomes thicker at the Globus minor of the epididymis, its windings become 

 less and less tortuous, and now the Vas dcferens is formed, which ascends 

 from the lower end of the epididymis along the back of the testicle; 

 it then passes in the spermatic cord to the inguinal canal, through this 

 to the abdominal cavity and the posterior wall of the bladder, and finally 

 opens at the base of the bladder, after union with the corresponding 

 seminal vesicle, in the Caput gallinaginis. 



Attached to the upper end of the testis or to the epididymis are 

 one or more small pedunculated bodies; these are termed Hydatis Moryagni 

 (see Fig. 405). With the duct of the epididymis is often connected a 

 small convoluted duct, the Vasculum aberrans Holler t.
