What is the function of the pectoral girdle?
Expert Solution & Answer
Summary Introduction
To review:
The function of the pectoral girdle.
Introduction:
The pectoral girdle is also known as shoulder joint. It is a part of the appendicular skeletal system. It is joined to the axial skeleton and attached to the bone of the upper limb. The pectoral girdle is formed by attachment of the clavicle, humerus bone, and scapula bone.
Explanation of Solution
The appendicular skeletal system consists of bones that are connected with the axial skeletal system by different types of joints. The clavicle and scapula are the two bones of the appendicular skeleton, which join together to form pectoral girdle. Humerus bone is fitted in the pectoral girdle.
It helps in the mobility of the upper limbs of the body, which include the hands and shoulders. It facilitates the bending and rotation of the hands along the shoulder. It also enables to lift heavy objects.
Conclusion
Hence, the pectoral girdle provides movement to the upper limbs of the body.
