Math upright Latin and Greek styles

isn't it specified in TeX using a font selection package instead of the
default one? Also the only upright letters I saw was for inserting normal
text (not mathematical symbols) or comments/descriptions, or when using the
standardized "monospace", or "serif" font (which are not italic by default).
