A likely etymologic source of the term “pectoral” is pectus, the Latin noun referring to the breast or mammary gland and, by extension, to the chest as a whole. On the other hand, pecten is Latin for comb; the pectoral region, then, may be so named because of the comb-like arrangement of ribs attaching to the sternum.
