Radiate
Radiate
Radiate (pronounced: /ˈrādēˌāt/) is a term used in various fields of medicine, including neurology, cardiology, and radiology. It is derived from the Latin word 'radiatus', meaning 'having rays'.
Definition
In a medical context, to radiate typically refers to the spreading out of pain or other sensations from a central point to other parts of the body. This is often used to describe the nature of pain in conditions such as angina or sciatica, where the pain may start in one area (the heart or lower back, respectively) and radiate outwards to other areas (such as the arm or leg).
