 Major; C, Globus Minor; D, Body of Epididymus; E F, Spermatic Cord. 



Testicle — The testicle is a compound tubular gland, ovoid in 

 form, suspended by the spermatic cord and occupying space in 

 the scrotum, inguinal canal or abdominal cavity. When in the 

 scrotum it is contained in a sac known as the tunica vaginalis. 



They vary much in size in different subjects and are often of 

 unequal size in the same individual. The epididymus (D, Fig. 10) 

 is an elongated ])ody extending along upper border of the testes 

 (A). It consists of a body (D), a head or globus major (B), 

 and a tail or blobus minor (C). 



Vas Deferens — The vas deferens is a firm hard tube which, after 

 leaving the globus minor, ascends the back of the spermatic cord 

 through the external abdominal ring, inguinal canal, and internal 

 abdominal ring to the abdominal cavity, where it enters the ])elvis, 

 passing to the antero-lateral aspect of the bladder, where it is 

 joined by the duct of the vesicula seminales. This union of ducts 

 takes place in the vicinity of the postate gland. 



nature's methods of controlling hemorrhage. 



It is well to always bear in mind the fact that nature is a great 

 factor in controlling arterial hemorrhage. To understand exactly 

 what nature causes to take place when an artery is severed is 

 knowledge which is never harmful to the surgeon, to say the least 

 of it. The following ha])pens as soon as an artery is severed:
