DISSECTING MANUAL. 



plan tubes, its sides are convex inward, and its apex is directed 

 downward; its walls are smooth. The cavity of the cervix 

 (cervical canal) is spindle-shaped, and communicates with the 

 cavity of the body by a circular orifice (internal os), and with 

 the vagina by another (external os) . On its walls the mucous 

 membrane forms an anterior and a posterior fold, with sec- 

 ondary folds branching obliquely from them (arbor vitse, or 

 plicae palmatsp). [1188] 



The peritoneum which covers the fundus descends ante- 

 riorly on the body to the junction with the cervix, and then 

 passes (utero-vesical fold, or " anterior ligament ") to the blad- 

 der, forming the utero-vesical pouch. Posteriorly it descends 

 over the body, supra-vaginal cervix, and upper part of the pos- 

 terior vaginal wall before passing (recto-vaginal fold) to the 

 rectum, forming the pouch of Douglas. On each side a fold 

 (recto-uterine, or fold of Douglas) runs from the back of the 

 cervix to the pelvic wall beside the rectum; fibrous and mus- 

 cular tissue pass in each fold to the rectum (Recto-uterine 

 muscle) and front of the sacrum (utero-sacral ligament) . The 

 broad ligament is formed by the peritoneum of the surfaces 

 passing from the lateral border, on each side, in a rather 

 vertical fold to the lateral pelvic wall. Its free upper edge 

 contains the Fallopian tube, forming a triangular mesentery 

 (mesosalpinx) whose apex is at the lateral angle; this 

 overhangs the ovary, forming a pocket for it (bursa ovarii). 

 From its posterior layer a short mesentery (mesovarium) 

 runs to the hilus of the ovary. The part below the meso- 

 salpinx, separated by the ligament of the ovary, is the 

 mesometrium. [1189] 



The round ligament is a narrow fibrous band attached to the 

 uterus just in front of and below the Fallopian tube. It runs 

 in the front of the broad ligament to the pelvic wall, then for- 

 ward and slightly upward over the obliterated hypogastric 

 artery and pelvic brim, to follow the course of the vas deferens 

 through the inguinal canal and end in the labium majus. Near
