Etymology: "Sulcations" is the plural of "sulcation," a noun for a groove or furrow, particularly one in body tissue. The singular comes from Latin "sulcatio," a derivative of "sulcare," meaning "to furrow" or "to plough," which is itself from "sulcus," a furrow. The ancient furrow sense survives in the anatomical use: in medicine, the word picks out the grooves and fissures that mark the surface of organs such as the brain, where the folds of tissue leave channels between them.

Synonyms: grooves, furrows, fissures, creases, wrinkles
