The chin is the lower part of the face that is formed by the tip of the lower jawbone. It protrudes differently in each person, with men usually having a more prominent chin than women.
Hair growth on the chin is commonly referred to as a goatee or chin beard. A hanging area between the chin and neck is known as a double chin, which is often associated with being overweight.
