Can anyone explain the difference between transverse and longitudinal section?

Or are they the same?

For an animal with bilateral symmetry, a longitudinal section is parallel to the anterior-posterior axis (labelled central axis in the image below). Sections through or parallel to either the sagittal or coronal (also called frontal) plane are longitudinal. A transverse section is perpendicular to the anterior-posterior axis and is also called a cross section.
