väliskõrvljuha

Väliskõrvljuha refers to the outer part of the ear, commonly known as the auricle or pinna. It is a complex cartilaginous structure covered by skin that plays a crucial role in collecting and directing sound waves into the ear canal. The unique shape of the väliskõrvljuha, with its various folds and curves, is essential for localizing sound sources, especially in the vertical plane.

The väliskõrvljuha is primarily composed of elastic cartilage, which provides its shape and resilience. It is attached to the head by skin and muscles, though the muscles are less developed and contribute minimally to sound collection in humans. The visible parts of the väliskõrvljuha include the helix, the antihelix, the concha, the tragus, and the lobule (earlobe). The lobule, unlike the rest of the väliskõrvljuha, is composed of fatty tissue and lacks cartilage.

Variations in the shape and size of the väliskõrvljuha are normal and contribute to individual differences. Medical conditions can sometimes affect the väliskõrvljuha, such as deformities present at birth or injuries sustained later in life. Despite its intricate structure, the primary function of the väliskõrvljuha is passive sound collection. Its detailed anatomy has been a subject of study in fields ranging from audiology to forensic science.
