What does the axial skeleton consist of?

The axial skeleton specifically encompasses the central core of the human body, which includes the skull, rib cage, and vertebral column. This section of the skeleton is primarily responsible for protecting vital organs, providing structural support, and serving as an attachment point for muscles.

The skull houses and protects the brain, while the rib cage encases the heart and lungs, allowing for respiratory movements. The vertebral column, or spine, not only supports the head but also protects the spinal cord and maintains the body’s upright posture.

In contrast, the other options pertain to different parts of the body. The hands and feet are part of the appendicular skeleton, which includes the limbs and their attachments. The pelvic girdle and limbs also belong to the appendicular skeleton, emphasizing movement and interaction with the environment. The notion of including all bones in the body inaccurately encompasses both the axial and appendicular skeletons, which are distinct divisions of the overall skeletal structure. Therefore, focusing on the specific components of the axial skeleton clarifies why the rib cage, skull, and vertebral column are the correct elements in this context.
