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

Options

A. vertebrae
B. nails
C. ear ossicles
D. tip of the nose

Explanation

**Step-by-Step Solution:**

1. **Identify the Tissue in Question**: The question asks about the type of tissue that provides support in the pinna (external ear). This tissue is known as elastic cartilage.

2. **Function of Elastic Cartilage**: Elastic cartilage is a flexible type of cartilage that provides support while allowing for some degree of flexibility. It is characterized by its yellowish color and the presence of numerous elastic fibers.

3. **Locate Other Areas Where Elastic Cartilage is Found**: The question requires us to find other locations in the body where elastic cartilage is present. Apart from the pinna, elastic cartilage is also found in:
- The tip of the nose
- The Eustachian tubes (auditory tubes)
- The epiglottis

4. **Evaluate the Options Given**: The options provided in the question need to be evaluated to find the correct answer:
- **Option 1: Vertebrae** - These contain calcified cartilage or fibrous cartilage, not elastic cartilage.
- **Option 2: Nails** - Nails are made of hard keratin, not cartilage.
- **Option 3: Ear ossicles** - These are bony structures, not cartilaginous.
- **Option 4: Tip of the nose** - This is indeed made of elastic cartilage.

5. **Select the Correct Answer**: Based on the evaluation, the correct answer is **Option 4: Tip of the nose**, as it is the only option that contains elastic cartilage like the pinna.

**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**.
