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

Options

A. Ligaments
B. Areolar tissue
C. Bone
D. cartilage

Answer

To answer the question regarding the supportive skeletal structures in the human external ears and nose tip, we will analyze the options provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the supportive skeletal structures found in the human external ears and the tip of the nose. We need to identify which type of tissue provides this support.

2. **Analyzing the Options**:
- **Option 1: Ligament** - Ligaments are connective tissues that connect bones to other bones. They provide stability to joints but are not primarily responsible for the structure of the ears or nose.
- **Option 2: Areolar Tissue** - Areolar tissue is a type of loose connective tissue that supports various organs and structures in the body. However, it does not provide the rigid support needed for the ears and nose.
- **Option 3: Bone** - Bone is a hard and rigid structure that provides support and protection to the body. While bones are important for overall structure, they are not the primary supportive tissue in the external ears and nose tip.
- **Option 4: Cartilage** - Cartilage is a type of connective tissue that is more flexible than bone. It provides support while allowing for some flexibility, making it ideal for structures like the external ears and the tip of the nose.

3. **Identifying the Correct Answer**: Based on the analysis, the supportive skeletal structures in the human external ears and nose tip are made of **cartilage**. Therefore, the correct answer is **Option 4: Cartilage**.

### Final Answer:
The supportive skeletal structures in the human external ears and nose tip are of **cartilage**.
