Although it probably makes you think more of snakes than head colds, "sinuous" is etymologically more like "sinus" than "serpent." "Sinuous" and "sinus" both derive from the Latin noun "sinus," which means "curve, fold, or hollow." Other "sinus" descendents include "insinuate" ("to impart or suggest in an artful or indirect way") and two terms you might remember from math class: "sine" and "cosine." In English, "sinus" is the oldest of these words; it entered the language in the 1400s. "Insinuate" appeared next, in 1529, and was followed by "sinuous" (1578), "sine" (1593), and "cosine" (1635). "Serpent," by the way, entered English in the 13th century and comes from the Latin verb "serpere," meaning "to creep."
