What does the sagittal axis pass through?

The sagittal axis runs horizontally and passes through the body from posterior to anterior. This axis is essential for movements that occur in the sagittal plane, such as flexion and extension. When performing activities like a bicep curl or a squat, the motion occurs around this axis, allowing for forward and backward movements. The orientation of the sagittal axis is crucial for understanding biomechanics and how the body moves in different types of exercises and sports.

In contrast, the other options describe different orientations and axes that are not aligned with the sagittal plane or its corresponding axis. Understanding this alignment is vital for analyzing human movement and improving performance in physical education.
