How does the human skeleton support the body?

The human skeleton serves as the internal framework for the body, providing essential support through its structure of bones and cartilages. As the most primitive and oldest function of the skeletal system, support is primarily managed by the axial skeleton.12

The vertebral column, which corresponds to the notochord in lower organisms, acts as the main support for the trunk. In humans, the skeleton has also adapted to accommodate an erect posture, functioning much like a tower supported by the legs. These adaptations are critical for weight-bearing, a significant mechanical challenge posed by the human upright stance.12

Beyond structural support, the skeleton works in tandem with ligaments, tendons, and skeletal muscles to facilitate movement and protect vital organs, ensuring the body maintains its integrity and functionality.12
