Eccentric
Eccentric
Eccentric (pronunciation: /ɪkˈsɛntrɪk/) is a term used in various fields of study, including medicine, to describe something that deviates from the norm or from what is considered conventional.
Etymology
The term "eccentric" is derived from the Greek word "ἐκκεντρικός" (ekkentrikos), which means "out of the center". It is composed of two parts: "ἐκ-" (ek-), meaning "out of", and "κέντρον" (kentron), meaning "center".
Medical Usage
In the field of medicine, the term "eccentric" is often used to describe a type of contraction in muscle physiology. An Eccentric contraction is the lengthening of the muscle during contraction, as opposed to concentric contraction, where the muscle shortens.
Eccentric is also used in the context of Eccentric hypertrophy, a condition where the heart muscle thickens in response to increased stress or disease, leading to an abnormal shape and function of the heart.
