Concavity
Concavity
Concavity (/kɒnˈkeɪvɪti/), also known as concave shape or concave figure, is a term used in various fields such as mathematics, physics, and medicine to describe a shape or surface that curves inward or is thinner in the middle than on the edges.
Etymology
The term "concavity" is derived from the Latin word "concavus", which means "curved inwards". "Concavus" itself is a combination of "con-", meaning "together" or "with", and "cavus", meaning "hollow" or "cavity".
In Medicine
In the field of medicine, concavity is often used to describe the inward curvature of a part of the body, such as the concavity of the spine or the chest. It can also refer to the space within a hollow organ or structure, such as the stomach or the eye.
