"earlobe" 的定义和意义

What is "earlobe"?

The earlobe is the soft, fleshy part at the bottom of the external ear, hanging down below the ear canal. It is composed mainly of skin and fat, lacking the cartilage found in the rest of the ear. The earlobe is highly variable in size, shape, and texture among individuals and can be pierced for the purpose of wearing earrings or other forms of body adornment. It serves primarily as a decorative and aesthetic feature of the ear, with no direct role in hearing or sound perception.
