Convex
Convex (/kɒnvɛks/; from Latin convexus, meaning "curved or rounded outward") is a term used in various fields of study such as mathematics, physics, and medicine. In a medical context, it often refers to a surface or structure having an outward curvature.
Etymology
The term "convex" is derived from the Latin word convexus, which means "curved or rounded outward". It is composed of con- ("together, with") and vexus ("curved, bent").
Medical Usage
In medicine, the term "convex" is often used to describe the shape of certain body parts or structures. For example, the anterior surface of the cornea is often described as being convex, meaning it curves outward. Similarly, the lens of the eye is also convex, allowing it to focus light onto the retina.
