The ventral end of ribs to sternum is connected together by :

Options

A. Hyaline cartilage
B. Articular cartilage
C. White fibrocartilage
D. Yellow elastic cartilage

Answer

To answer the question, "The ventral end of ribs to sternum is connected together by:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question asks about the type of cartilage that connects the ventral ends of the ribs to the sternum.

2. **Identifying the Options**:
- The options provided are:
- A) Hyaline cartilage
- B) Articular cartilage
- C) White fibrocartilage
- D) Yellow elastic cartilage

3. **Analyzing Each Option**:
- **Option A: Hyaline Cartilage**:
- This type of cartilage is known to connect the ribs to the sternum. It provides flexibility and support, which is essential for the ribcage's function during breathing.
- **Option B: Articular Cartilage**:
- This cartilage covers the ends of bones in synovial joints, not the connection between ribs and sternum. Therefore, this option is incorrect.
- **Option C: White Fibrocartilage**:
- This type of cartilage is more fibrous and is found in areas requiring tensile strength, such as intervertebral discs. It does not connect ribs to the sternum, making this option incorrect.
- **Option D: Yellow Elastic Cartilage**:
- This cartilage is more flexible and found in structures like the ear and epiglottis. It does not play a role in connecting ribs to the sternum, so this option is also incorrect.

4. **Conclusion**:
- After analyzing all the options, we find that the correct answer is **A) Hyaline cartilage**. This cartilage connects the ventral ends of the ribs to the sternum.

### Final Answer:
The ventral end of ribs to sternum is connected together by **Hyaline cartilage**.
