fatty, vascular tissue previously mentioned as the parametrium. 

 The opening of the lower end of the vagina into the urino- 

 genital cleft is partly closed, in the virgin, by the hymen. 

 This is formed by two antero-posteriorly placed crescentic 

 folds which are united in front and behind. After the 

 hymen has been ruptured, its torn fragments, called carun- 

 culcs hymenahs, persist round the opening.

The Relations of the Vagina. The posterior wall of the 

 vagina is in relation above with the recto-vaginal excavation of 

 peritoneum. Below this it is in apposition with the anterior 

 wall of the rectum (Fig. 244). The anterior wall of the 

 vagina is related to the lower part of the base of the bladder 

 and to the urethra. The lower end of the vagina is embraced 

 between the vestibular bulbs, and is clasped by the sphincter 

 vaginae, and each lateral border is supported by the corre- 

 sponding levator ani muscle. The anterior borders of the 

 levatores ani muscles, as they pass backwards from the body
