Prolapse literally means "to fall out of place‚" from the Latin prolabi meaning "to fall out." In medicine, prolapse is a condition where organs, such as the uterus, fall down or slip out of place. It is used for organs protruding through the vagina or the rectum or for the misalignment of the valves of the heart. A spinal disc herniation is also sometimes called "disc prolapse."
Relating to the uterus, prolapse condition results in an inferior extension of the organ into the vagina, causing weakened muscles.
