What is the lower part of the pinna that contains no cartilage called?

• A. Lobe
• B. Helix
• C. Styloid process
• D. Antihelix

Answer: (A)

The lower part of the pinna that contains no cartilage is referred to as the lobe. The lobe is composed of soft tissue and fatty tissue, unlike other parts of the pinna which are supported by cartilage. This structural difference is significant because it affects the flexibility and physical properties of the lobe compared to the rest of the ear. The lobe plays a minor role in the overall function of hearing, but it is an important anatomical feature of the outer ear, providing the distinct shape associated with human ears. Understanding the anatomy of the pinna, including the lobe, is essential for professionals in audiology and hearing instrument fitting as it helps them communicate effectively about ear structures with clients and colleagues.
