Terminology?
Viktorie Halasu,

I would like to ask how to call correctly a preparate that wasn't cut radially, from margin to centre, but on the secant - a thin section of the surface layer. It has its use e.g. in Scutellinia where you get bigger sample of the hairs and yet the section is thin enough to clearly see the hair roots (if you place it hairs down). Unlike "radius - radial", there doesn't seem to be an adjective from "secant", only adverb. I'm looking for something short to use in image descriptions, like "radial section" vs. "xxxx section". Would "secant section" make any sense to you, or is it a nonsense in english?
Thank you in advance for any help.

Re : Terminology?
Hi Viktorie,
I would use the term "parallel (to / with) the surface" for such a section

Re : Terminology?
Stip's is a good suggestion. I think "tangential section" would also cover what you are intending.

Re : Terminology?
Thank you both.
"Tangential section" is what I've been actually using in my notes, but it's not correct (it's a secant, not tangent). But if nothing better appears, I'll probably use one of your suggestions.

Re : Terminology?
Hi Viktorie,
I would follow the terminology used also in wood sections. In your case it would be tangential, even if it is in fact a secant in geometry. It describes the direction only of the cut. See this examples:
(cross section = transverse section)
Best regards

Re : Terminology?
Hello Martin,
oh of course, I forgot about wood sectioning, that's a good terminological precedent.
Thank you.
