| chromatoid | A refractile substance composed of chromatin, thought to be a non-glycogen food reserve contained within the cytoplasm of certain protozoa; seen in cysts of Entamoeba histolytica as rounded bars or chromatoidal bodies in contrast to the splintery form of chromatoid bodies in cysts of Entamoeba coli.

| chromatolysis | The disintegration of the granules of chromophil substance (Nissl bodies) in a nerve cell body which may occur after exhaustion of the cell or damage to its peripheral process; other changes considered part of chromatolysis include swelling of the perikaryon and shifting of the nucleus from its central position to the periphery.
