The correct Answer is:
To solve the question, we need to identify the type of tissue that forms the supportive structure in our pinna (external ears) and determine where else this type of tissue can be found. ### Step-by-Step Solution: 1. **Identify the Tissue Type**: - The supportive structure of the pinna (external ear) is made up of cartilage tissue. Cartilage is a flexible connective tissue that provides support and shape. 2. **Understand the Properties of Cartilage**: - Cartilage consists of widely spaced cells and has a solid matrix made of proteins and sugars. It serves to smooth the surfaces of bones at joints and is crucial in various parts of the body. 3. **Evaluate the Options**: - **Option A: Ear Ossicle**: This is a bone structure in the middle ear, not cartilage. - **Option B: Tip of Nose**: The tip of the nose is made of cartilage, which supports its structure. - **Option C: Vertebrae**: Vertebrae are made of bone, not cartilage. - **Option D: Nails**: Nails are made of keratin, not cartilage. 4. **Select the Correct Answer**: - Since cartilage is found in the tip of the nose (Option B), this is the correct answer. ### Final Answer: The kind of tissue that forms the supportive structure in our pinna (external ears) is also found in the **tip of the nose**. ---
