प्रश्न
Answer the following question.
What enables the ear pinna to be folded and twisted while the nose tip can’t be twisted?
उत्तर
- The ear pinna (outer ear) is made up of a thin plate of elastic cartilage and is connected to the surrounding parts by ligaments and muscles. This elastic cartilage gives support and maintains the shape of pinna.
- The nose tip is made up of elastic cartilage. However, several bones and cartilage make up the bony cartilaginous framework of the nose.
Hence, even though the tip of the nose is made up of elastic cartilage, it cannot be twisted like the ear pinna due to the presence of a bony-cartilaginous framework.
