(鼓膜)
耳膜
a thin piece of skin in the middle ear that vibrates by sound waves and enables one to hear sounds, also known as tympanic membrane
The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane located in the middle ear. It separates the outer ear from the middle ear and plays a crucial role in the process of hearing. When sound waves enter the ear, they cause the eardrum to vibrate, which in turn transmits these vibrations to the bones of the middle ear, allowing sound to be amplified and transmitted further into the inner ear for processing.
(耳朵柔软部分)
耳垂
the soft fleshy part of the external ear
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.
