What is the part of the skeleton that comprises the skull, spinal column, and rib cage called?

The part of the skeleton that comprises the skull, spinal column, and rib cage is called the axial skeleton. This section of the skeleton serves several crucial functions, including protecting vital organs, such as the brain and heart, and providing structural support for the body.

The axial skeleton includes the cranium, which encloses the brain; the vertebral column, which protects the spinal cord; and the rib cage, which safeguards the heart and lungs. By serving as a central framework for the body, the axial skeleton plays an essential role in maintaining stability and posture, as well as facilitating movement through its connection with the appendicular skeleton (which includes the limbs). Understanding the distinction between the axial skeleton and other parts, such as the appendicular skeleton or the facial skeleton, is vital for comprehending human anatomy and the overall organization of the skeletal system.
