ABDOMEN 



the gland which it envelops. It ascends for some distance 

 upon the spermatic cord, and it even descends beyond the 

 testis. When flaccid, the parietal part is simply wrapped 

 loosely over the visceral portion which adheres to the surface 

 of the testis.

Dissection. Open into the sac of the tunica vaginalis by running a pair 

 of scissors along the anterior aspect of the parietal part. When the parietal 

 portion of the tunica vaginalis is folded backwards the form of the testis 

 may be studied, and also the manner in which it is attached to the posterior 

 wall of the sac. 



Body of the Testis and Epididymis. The testis is an oval 

 body, with flattened sides. The posterior margin is also some- 

 what flattened, and is in relation with the epididymis. This is an 

 elongated and arched structure, which is adapted to the superior
