prolapse
This term carries a clinical and often distressing weight, evoking a sense of structural failure or a loss of internal support. It describes a specific physical descent where gravity and pressure overcome the tissues meant to hold an organ in place, creating a feeling of instability or exposure.
In medical discourse, it is used with precise anatomical targets to describe a failure of the pelvic floor or other supporting ligaments. Outside of a medical setting, it is rarely used metaphorically, as its visceral association with bodily malfunction makes it too graphic for most figurative applications.
Countable when referring to a specific medical occurrence or diagnosis (a prolapse). Uncountable when referring to the general physiological process of slipping downward.
