What is a primary function of the axial skeleton?

The primary function of the axial skeleton is to support and protect the body's vital organs. It includes key structures such as the skull, vertebral column, and rib cage, all of which play crucial roles in safeguarding essential organs like the brain, heart, and lungs. The axial skeleton serves as a central framework for the body, enabling it to maintain its shape and providing a stable base for the attachment of other skeletal components.

While the other choices represent important functions of various body systems or other parts of the skeleton, they do not capture the fundamental role of the axial skeleton itself. For instance, facilitating limb movement pertains more to the appendicular skeleton, which is designed for mobility. Providing muscle attachment points is indeed a function of bones in general, but the axial skeleton's primary role centers on protection and support. Similarly, while storing minerals is a function of bones overall, it is not specific to the axial skeleton.
