Skeletal tissue found in mammalian pinna is

Options

A. Calcified cartilage
B. Fibrous cartilage
C. Simple cartilage
D. Elastic cartilage .

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:**
- The question asks about the type of skeletal tissue found in the mammalian pinna, which is the outer part of the ear.

2. **Identifying the Pinna:**
- The pinna is the visible part of the ear and has a distinct helical shape. It plays a role in capturing sound waves.

3. **Analyzing the Options:**
- The options given are:
1. Classified cartilage
2. Fibrous cartilage
3. Simple cartilage
4. Elastic cartilage

4. **Evaluating Each Option:**
- **Classified Cartilage:** This type of cartilage is a thin interlayer found between hyaline and articular cartilage. It is not found in the pinna, so this option is incorrect.
- **Fibrous Cartilage:** This cartilage is tough and strong, found in structures like intervertebral discs. It is not present in the pinna, making this option incorrect as well.
- **Simple Cartilage:** Also known as smooth cartilage, it is found in various body parts but is not specific to the pinna. Therefore, this option is also incorrect.
- **Elastic Cartilage:** This type of cartilage is flexible and yellow in color, specifically found in the pinna. It allows the pinna to maintain its shape while being somewhat pliable.

5. **Conclusion:**
- The correct answer is **Elastic Cartilage**, as it is the type of skeletal tissue that makes up the mammalian pinna.

**Final Answer:**
The skeletal tissue found in the mammalian pinna is **Elastic Cartilage**.
