What does the suffix "-plegia" signify in medical terms?

The suffix "-plegia" is derived from Greek, where it specifically denotes paralysis or a condition involving loss of motor function. In medical terminology, it is commonly used to describe different types of paralysis based on the affected area of the body. For example, "hemiplegia" refers to paralysis on one side of the body, while "quadriplegia" indicates paralysis of all four limbs.

Understanding this suffix allows healthcare professionals to accurately describe and understand conditions affecting motor function in patients, which is crucial for diagnosis and treatment planning. The nature of the other choices does not align with the meaning of "-plegia," as they refer to falling, examination, or tying/binding, which do not pertain to paralysis or loss of movement.
