1. in complete sentences, describe the main function(s) of this body system:

axial
skeleton

Explanation:

The axial skeleton's core functions include protecting vital internal organs, providing structural support for the body's central axis, enabling foundational movements like head and spinal motion, and serving as attachment points for muscles that control posture and core actions.

Answer:

The main functions of the axial skeleton are:

1. It protects critical internal organs, such as the brain (via the skull), spinal cord (via the vertebral column), and the heart and lungs (via the ribcage).
2. It provides a rigid central structural framework that supports the weight of the upper body and maintains overall body posture.
3. It acts as an attachment site for muscles that control head, neck, and trunk movements, as well as muscles involved in breathing.
4. It houses and protects the bone marrow in the skull, vertebrae, and sternum, which is responsible for producing blood cells.
