What is the role of the axial skeleton primarily?

The axial skeleton plays a crucial role in supporting the body's structure. It consists of the skull, vertebral column, and rib cage, forming the central framework that maintains the body's shape and provides stability. This structure not only supports the head and trunk but also serves as an attachment point for various muscles, allowing for movements while ensuring alignment of the body.

Supporting the body’s structure is essential for maintaining posture and balancing, which are vital during physical activities, including movements in Reformer Pilates. While protection of vital organs and facilitating movement are also important functions of the axial skeleton, its primary role is indeed to provide overall structural support.
