Supportive skeletal structures in the human external ears and nose tip are of

Options

A. Ligament
B. Areolar tissue
C. Bone
D. Cartilage

Answer

To answer the question about the supportive skeletal structures in the human external ears and nose tip, we will analyze the options provided: ligament, areolar tissue, bone, and cartilage.

### Step-by-Step Solution:

1. **Understanding the Structures**:
- The external ear and the tip of the nose require a supportive structure that is both flexible and firm. This is essential for their shape and function.

2. **Analyzing the Options**:
- **Ligament**: This is a type of fibrous connective tissue that connects bones to other bones. It is not flexible enough to provide support for the ear and nose.
- **Areolar Tissue**: This is a loose connective tissue that supports organs and blood vessels but does not provide the rigidity or structure needed for the external ear and nose.
- **Bone**: Bone is a rigid and strong tissue that forms the skeleton. However, it is too hard and inflexible for the structures of the ear and nose.
- **Cartilage**: This is a type of connective tissue that is smooth, flexible, and firm. It provides the necessary support while allowing for some flexibility, making it ideal for the external ear and nose tip.

3. **Conclusion**:
- Based on the analysis, the supportive skeletal structures in the human external ears and nose tip are made of **cartilage**.

### Final Answer:
The correct answer is **cartilage**.
