Verified step by step guidance

Understand the anatomy of the pectoral girdle: The pectoral girdle, also known as the shoulder girdle, consists of the clavicles (collarbones) and the scapulae (shoulder blades). It connects the upper limb to the trunk of the body.

Identify the primary function: The main role of the pectoral girdle is to provide attachment points for muscles. These muscles are responsible for the movement of the upper limbs, including the arms and shoulders.

Consider the movement facilitation: The pectoral girdle allows for a wide range of motion in the shoulder joint, which is crucial for various activities such as lifting, pushing, and pulling.

Differentiate from other functions: While the pectoral girdle does not primarily support the weight of the body or protect internal organs like the heart and lungs, it plays a crucial role in upper limb mobility.

Conclude with the correct function: The primary function of the pectoral girdle is to provide attachment points for the muscles that move the upper limbs, enabling a wide range of movements and flexibility.
