Clavicle is also known as :

Question

Accepted Answer

The clavicle, commonly referred to as the "collarbone," is a long bone that serves as a strut between the shoulder blade and the sternum. It is an essential part of the shoulder girdle, providing structural support and facilitating arm movement. The term "collar" in Option 3 is a colloquial reference to the clavicle, as it is located in the area commonly associated with the collar of a shirt.

1. **Explanation for Option 3 (Collar):**
   - The clavicle is often called the "collarbone" because of its location and function. It is situated horizontally across the top of the chest, forming a part of the shoulder girdle and connecting the arm to the body. This bone is crucial for stabilizing the shoulder and allowing a wide range of arm movements. The term "collar" is derived from its position near the neck, similar to where a shirt collar would be.

2. **Explanation for why other options are incorrect:**
   - **Option 1 (Scapula):** The scapula, or shoulder blade, is a different bone located on the back of the ribcage. It is a flat, triangular bone that connects with the clavicle and humerus to form the shoulder joint. While it is part of the shoulder girdle, it is not synonymous with the clavicle.
   - **Option 2 (Fibula):** The fibula is a bone in the lower leg, running parallel to the tibia. It is not part of the shoulder girdle and has no connection to the clavicle. Its primary function is to provide stability to the ankle and support muscles of the lower leg.
   - **Option 4 (Sleeve):** The term "sleeve" does not refer to any bone in the human body. It is typically used to describe a part of clothing that covers the arm. Therefore, it is not related to the clavicle in any anatomical context.

In conclusion, Option 3, "Collar," is the correct answer because it accurately reflects the common name for the clavicle, highlighting its anatomical position and function.
