The terms longitudinal and transverse refer to different orientations or directions of a section or cut through an object.
A longitudinal section is a cut that runs along the long axis of an object, dividing it into two parts, left and right. For example, if you were to cut an apple in half from stem to bottom, the resulting sections would be longitudinal sections.
In contrast, a transverse section is a cut that runs perpendicular to the long axis of an object, dividing it into two parts, top and bottom. For example, if you were to cut an apple in half around its equator, the resulting sections would be transverse sections.
Therefore, if we know that section X is a transverse section and section Y is a longitudinal section, we can conclude that the answer is "transverse and longitudinal". If the question had been reversed, with X being longitudinal and Y being transverse, the answer would be "longitudinal and transverse".
