All of the Following are True Regarding the Pectoral Girdle

Question

All of the following are true regarding the pectoral girdle except
A) it attaches the upper limb to the trunk.
B) only the clavicle articulates with the axial skeleton.
C) it is gives stability but restricts mobility of the upper limbs.
D) its bones contain many attachment points for muscles of the upper extremity.

Accepted Answer

The pectoral girdle is designed to provide a wide range of motion for the upper limbs, rather than restricting mobility. It achieves this through its relatively loose attachment to the axial skeleton, primarily at the sternoclavicular joint, allowing for significant flexibility and movement.
