Origin: Greek

Gr. splanchna = viscera or internal organs. This adjective is applied, for example, to the nerve supplying the viscera.

Gr. splen = spleen, perhaps originally related to splanchna = viscera. In Latin this root became lien after losing its initial sp. From splen, of course, comes splenic and the combining form spleno-.

Gr. squama = fish-scale.

Gr. stenos = narrow, -osis = condition. Applied to any narrowing of tubular structure, such as an artery, heart valve, or the esophagus.

Gr. sternon = the male chest, until Galen limited its meaning to the breast bone.

Gr. stomachos;  originally derived from stoma = mouth, and for a time applied to the esophagus, with the thought that the gullet is the mouth of the stomach.

Gr. stylos = pillar, and eidos = resemblance. Applied to the styloid process of the temporal bone.

Gr. syn = with, and pathos = suffering.

Gr. symphysis  = a growing together, from syn = with, and physis = growth. Hence a union, but not a true joint.
