The round ligament in its course through the canalis inguinalis. The ligament is drawn slightly 

 downward. (In greater part after Waldeyer.) (From Poirier et Charpy, Traitt* d'Anat. hum., Paris, 

 1901, t. ii. p. 436, Fig. 315.) 



Testis (Testicle). (Vide Figs. 237, 239, 240.) 



Note its position in the scrotum and the relation to it of the 

 proper vaginal tunic (tunica vaginalis propria testis). Distin- 

 guish a parietal layer (lamina parietalis) and a visceral layer 

 (lamina visceralis). Where does the testis originate and how 

 does it reach its position in the scrotum? Where may it be 

 arrested in its descent and what is the resultant condition? 



Cut through the lamina parietalis along its anterior aspect. 

 Examine 



(a) Superior extremity of testicle (extremitas superior). 



(b) Inferior extremity (extremitas inferior). 



(c) Lateral surface (fades lateralis). 



(d) Medial surface (fades medialis). 



(e) Anterior margin (mar go anterior). 



(f) Posterior margin (margo posterior).
