Final answer:
The scapula, or shoulder blade, is the bone that forms the pectoral girdle with the clavicle (collarbone), providing attachment points for the upper limbs and enabling a wide range of motion.
Step-by-step explanation:
The bone that is a part of the pectoral girdle along with the clavicle is the scapula. The pectoral girdle, also known as the shoulder girdle, includes two main bones: the clavicle, or collarbone, in the front, and the scapula, or shoulder blade, in the back.
The clavicle is S-shaped and located on the anterior (front) side of the shoulder, connecting to the sternum of the thoracic cage, while the scapula is a flat bone in the posterior (back) of the shoulder that helps to form the shoulder joint. Together, these bones provide attachment points for the upper limbs to the axial skeleton, allowing considerable range of motion and serving as a support framework.
The correct answer to the question 'Which bone is a part of the pectoral girdle along with the clavicle?' is a) Scapula.
