Etymology: "Sarcoplast" is a technical coinage built from two Greek elements. "Sarco-" comes from Greek "sarx," meaning flesh, and "-plast" comes from Greek "plastos," meaning formed or molded, the same root behind "plasm" and "plastic." Put together, the term describes something formed from or within flesh, and in biology it refers to the cytoplasm of a striated muscle cell, the substance surrounding its contractile fibres. Like many anatomical and cytological terms, it was assembled from classical Greek building blocks by modern scientists rather than inherited from ancient writers. The Greeks had "sarx" and "plastos" separately, but nothing called a "sarcoplast" until biologists needed a precise name for this part of the muscle cell.
