arcus
Curved anatomical structure
Arcus is a Latin term for arch or bow, appearing in English primarily in technical contexts.
In meteorology, an arcus cloud is a low, horizontal formation—either a shelf cloud or roll cloud—that appears at the leading edge of a thunderstorm.
In anatomy, arcus refers to arch-shaped structures: the arcus senilis is a whitish ring that forms around the cornea with age.
