There are two clavicle bones in the human body.
Understanding the Clavicle
The clavicle, also known as the collarbone, is a long, slender bone that plays a vital role in the shoulder's structure and function.
- Number: Each person has two clavicles, one on the right side and one on the left side of the body, as stated in the reference: "There are 2 clavicles in a person, one on the right and the other one on the left side."

The clavicle is essential for various functions:
- Shoulder Support: It helps support the shoulder and arm by connecting them to the torso.
