The term 'convoluted' derives from the Latin 'convolutus', past participle of 'convolvere' (to roll together, intertwine), from 'com-' (together) + 'volvere' (to roll). 'Tubule' stems from the Latin 'tubulus', a diminutive of 'tubus' (pipe or tube). Together, the anatomical phrase describes a microscopic, intricately coiled cylindrical structure found primarily in the kidney nephron.
