Verified step by step guidance

Understand the structure of the pectoral girdle: The pectoral girdle consists of the clavicles (collarbones) and the scapulae (shoulder blades). It connects the upper limb to the trunk and provides attachment points for muscles.

Consider the role of bone count in flexibility: Fewer bones in a structure can lead to increased flexibility because there are fewer joints and connections that need to be stabilized, allowing for more movement.

Evaluate muscle attachment sites: While more bones can provide more surface area for muscle attachment, fewer bones can still offer sufficient attachment points if they are well-designed and positioned.

Analyze structural stability: Fewer bones can enhance structural stability by reducing the number of joints, which are potential points of weakness. This can lead to a more stable and robust structure.

Assess range of motion: A reduced number of bones can increase the range of motion by allowing the remaining bones to move more freely without being restricted by additional joints.
