Final answer:
The synonym for darting pain is sharp pain, which matches the sudden and intense characteristics associated with darting pain. Other options such as dull, throbbing, and aching pain do not describe the quick, piercing sensation of darting pain. Sharp pain is also relevant in practical applications like the use of knives and hypodermic needles, illustrating how sharpness can reduce discomfort.
Step-by-step explanation:
The synonym for darting pain is 1) Sharp pain. Darting pain implies a sudden, intense, and often piercing quality of discomfort, which aligns with the characteristics of sharp pain. This type of pain is typically brief and sharply defined, much like the sensation caused by something that is pointed or has an edge. In contrast, dull pain refers to a more continuous, milder discomfort, throbbing pain involves a pulsating ache, and aching pain is a persistent and dull discomfort. Therefore, darting pain is most closely related to sharp pain.
Understanding the nature of sharp pain is important in fields such as medicine. For instance, the sharpness of a knife is directly related to how effectively it can cut, with pressure being focused over a smaller surface area when the blade is sharp. Consequently, a sharp blade provides a clean cut with less pressure required. Similarly, a sharp hypodermic needle causes less discomfort compared to a dull needle; the sharp needle pierces the skin more cleanly, causing a swift, sharp pain rather than a more painful sensation due to increased resistance met by a duller needle tip.
