Concave
Concave (/kɒnˈkeɪv/; from Latin concavus, "hollowed out") is a term used in various fields of study, including medicine, mathematics, and physics, to describe a surface or shape that curves inward or is thinner in the middle than at the edges.
In medicine, the term "concave" is often used to describe the shape of certain body parts or the appearance of certain medical conditions. For example, a concave chest (also known as pectus excavatum) is a condition where the breastbone sinks into the chest, creating a noticeable dip or hollow.
Etymology
