How are the pectoral and pelvic girdles structurally different? How is this difference reflected in their functions?
What will be an ideal response?
The pectoral girdle moves freely across the thorax and allows the upper limb a high degree of mobility, while the pelvic girdle is secured to the axial skeleton to provide strength and support. This is why the glenoid cavity of the scapula is relatively shallow and the acetabulum of the pelvis is a deep socket.
