When you uphold something, you stick up for or support it. Police officers are paid to uphold the law, and crazy Elvis fans uphold their belief that he's still alive out there somewhere. If you reverse the two parts of this word, you get hold up. And that's exactly what upholding is: holding up or supporting an idea or practice. You might uphold your dog's innocence, even though it's pretty obvious he dug up the neighbor's flower bed.

A petechia, plural petechiae, is a small (1â2 mm) red or purple spot on the skin, caused by a minor bleed (from broken capillary blood vessels). Petechia refers to one of the three descriptive types of bleeding into the skin differentiated by size, the other two being purpura and ecchymosis. Petechiae are by definition less than 3 mm. The term is almost always used in the plural, since a single lesion is seldom noticed or significant.
