The kind of tissue that forms the supportive structure in our pinna (external ears) is also found in

The pinna is supported by cartilage, a specialised connective tissue whose matrix is solid but pliable and resists compression.
In adults, cartilage is present in the tip of the nose, the outer ear joints, between adjacent bones of the vertebral column, and in the limbs and hands.
The vertebrae and ear ossicles are bones, and nails are made of the protein keratin.
Hence the same tissue is found in the tip of the nose.
