## Definition

relating to an axis, which is a straight line that something turns around. In biology, it describes things located in the center of a body or plant.

## Examples

- The wheel rotates around its axial center.
- The axial skeleton includes the skull, vertebral column, and rib cage, forming the central core of the human body.
- Engineers must calculate the axial load to ensure the central pillar can support the downward pressure of the entire roof without buckling under the stress.

## Usage notes
