Efferent
Efferent (pronounced: /ˈefərənt/) is a term used in anatomy and physiology to describe a process or structure that carries information or substances away from a central location or organ. The term is derived from the Latin word efferre, which means "to carry out" or "to conduct".
Etymology
The term "efferent" comes from the Latin word efferre, which is a combination of ex- (meaning "out of") and ferre (meaning "to carry"). Thus, in its most literal sense, "efferent" refers to something that carries things away or out.
Usage in Medical Context
