Anatomy - 4 body parts

Explanation:
Think about how the skeleton is organized: axial versus appendicular. The spine forms the central axis of the body, a vertebral column that protects the spinal cord and supports the torso. It also contributes to posture and flexibility. The pelvis, femur, and tibia are all part of the limbs (the hip girdle and the leg bones) and mainly serve to transfer weight and enable movement. Among these four structures, the spine is the one that defines the body's central axis and provides neural protection, making it the standout choice. The pelvis supports weight transfer from spine to legs, while the femur and tibia are long bones of the lower limb essential for locomotion.
