Answer:

Axial skeleton

The human skeleton is divided into two main divisions: the axial skeleton and the appendicular skeleton. The axial skeleton consists of the skull, the vertebral column, the sternum, and ribs. It plays a crucial role in providing protection to vital organs such as the brain, spinal cord, heart, and lungs.

The skull is made up of different bones that protect the brain and provide structure to the face. The vertebral column, also known as the spine, protects the spinal cord and provides support for the upper body. The sternum, commonly known as the breastbone, forms the front of the rib cage and protects the heart and lungs. The ribs, attached to the sternum, wrap around the chest cavity to protect the organs inside.

Overall, the axial skeleton is essential for maintaining the body's structure and protecting vital organs, highlighting the critical role of this skeletal division in the human body.
