Oral histology: cross section of the tooth

Hello, I have a simple question.

Does 'cross section' of a tooth means that we will have a look to the tooth from the facial aspect or the occlusal aspect?

And does longitudinal section means that the view we will get is of proximal aspect?

These conceptepts confuse me, and I hope someone will help me. I understand the concepts from a general histology point of view, but in oral histology, it seems that there is a difference.

Thanks in advance!

This is a ground cross section of a tooth near the cervical margin. The micrograph was taken using trans-mitted light. When the tooth is viewed in cross section, the changes in direction of the dentinal tubules are obvious. They radiate out from the pulp perpendicular to the inner and outer surfaces of the dentin. The S-shaped curvature of the tubule lies at right angles to the cross sectional plane.
