Patella is largest :-

Options

A. Membranous Bone (Develop in dermis )
B. Cartilage Bone (Replacing Bone)
C. Heterotypic Bone (Visceral Bone)
D. Sesamoid Bone (Develop in Tendon)

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the largest type of bone known as the patella.

2. **Identifying the Options**: The options provided are:
- Membranous bone developed in dermis
- Cartilage bone replacing bone
- Heterotypic bone (visceral bone)
- Sesamoid bone developed in tendons

3. **Defining the Patella**: The patella is commonly known as the kneecap. It is important to identify its classification.

4. **Classifying the Patella**: The patella is classified as a sesamoid bone. Sesamoid bones are bones that develop within tendons.

5. **Understanding Sesamoid Bones**: Sesamoid bones are formed by the ossification of tendons and serve to protect the tendons and increase their mechanical advantage.

6. **Comparing with Other Options**:
- **Membranous Bone**: This type of bone is developed in the dermis and is associated with intramembranous ossification, typically found in the skull and jaw.
- **Cartilage Bone**: This type is formed by replacing cartilage and includes bones like the mandible and clavicle.
- **Heterotypic Bone**: These are visceral bones found in organs, such as the heart and tongue.

7. **Conclusion**: Since the patella is a sesamoid bone and is known to be the largest sesamoid bone in the human body, the correct answer is the fourth option: "sesamoid bone developed in tendons."

**Final Answer**: The patella is the largest sesamoid bone developed in tendons.
