What are the components of the pectoral girdle in the appendicular skeleton?
The components of the pectoral girdle in the appendicular skeleton are two scapulae and two clavicles.
The pectoral girdle, part of the appendicular skeleton, consists of four bones: two scapulae and two clavicles. These bones play a crucial role in connecting the upper extremities to the axial skeleton, providing support and facilitating a wide range of movements. The clavicles attach the pectoral girdle to the axial skeleton at the sternum, allowing for the flexibility and mobility necessary for upper limb function.
