What does '-ptosis' signify in medical terminology?

The suffix '-ptosis' in medical terminology signifies a condition of drooping or falling. This term is derived from the Greek word "ptōsis," which means a falling or a downward displacement. It is often used in medical contexts to describe structural changes in the body, especially with regard to organs or tissues that have moved from their normal position. For example, "blepharoptosis" refers to the drooping of the eyelid, and "nephroptosis" describes a condition where the kidney descends from its usual position.

Understanding the meaning of '-ptosis' is crucial for grasping various medical conditions and their implications in diagnosis and treatment. The other options do not relate to this specific suffix; for example, spitting is associated with 'sialorrhea,' while terms related to meals usually involve 'meal' or 'postprandial.' Excessive flow is commonly indicated by 'hypersecretion' or 'excessive flow' terms, neither of which shares the same root as '-ptosis.'.
