Verified step by step guidance

Step 1: Understand the human skeletal system's organization. The skeletal system is divided into two main parts based on function and location: the axial skeleton and the appendicular skeleton.

Step 2: Define the axial skeleton. The axial skeleton includes the bones that form the central axis of the body, such as the skull, vertebral column, ribs, and sternum. These structures primarily provide support and protection for vital organs.

Step 3: Define the appendicular skeleton. The appendicular skeleton consists of the bones of the limbs and girdles (pectoral and pelvic girdles). These structures are involved in movement and interaction with the environment.

Step 4: Compare the given options. The axial and appendicular skeletons are the correct divisions, as they encompass all the bones in the human body. The other options (cranial and facial skeleton, vertebral and thoracic skeleton, upper and lower skeleton) are subsets or incorrect categorizations.

Step 5: Conclude that the correct answer is 'Axial and appendicular skeleton,' as these are the two main divisions of the human skeletal system.
