speculum placed into the vaginal vault to assess the walls of the vagina and external surface of the cervix then take pap smaer for cervical aner
72
Cystocele
bladder protrudes into the anterior aspects of the vagina
73
Descensus fo the cervix and uterus
cervix and uterus "fall" thru the vagina = protrusion
