👉 Protrusion is a term that refers to the protruding or visible part of an object, especially in the case of a body part. It can be a single point, such as a nose or chin, or it may involve multiple parts, such as a jawbone or a tooth. Protrusions are often associated with objects that have been cut or shaped, and they can also refer to the protruding areas on a person's face due to their facial structure.
