Final answer:
A uterine prolapse with the cervix protruding through the vagina is termed a complete prolapse.
Step-by-step explanation:
A uterine prolapse in which the cervix protrudes through the vagina to the exterior is a complete prolapse. The cervix is the neck of the uterus that protrudes down into the vagina, through which a canal connects the vagina and uterus. In the case of a complete prolapse, the entire uterus or a significant part of it descends so that the cervix, or even the entire uterus, comes out through the vaginal opening. This condition may require medical evaluation and treatment.
