Inclusion Bodies

 

in biology, all the structures of the cell cytoplasm. Inclusion bodies are usually divided into three groups: fixed bodies, or organoids, which carry out the general cell functions—for example, mitochondria, Golgi bodies, chloroplasts; temporary bodies, or paraplasmatic formations, which appear and disappear during metabolism—secretor granules, nutritive substances, fat, starch, and others; and specialized, or metaplasmatic, formations, which are found in some specialized cells, where they perform particular functions, such as contraction—the myo-fibrils of muscle cells—or support—the tonofibrils in epidermal cells.
