1852 T. Williams in Philos. Trans. (Royal Soc.) 142 595 The containing system of the blood-proper is distinguished..by the absence of vibratile cilia from its internal lining membrane, while that of the chylaqueous fluid is provided in the same situations, almost invariably, with these motive organules.
1981 Amer. Jrnl. Bot. 68 1034/2 Rare organules are visible in the cytoplasm.
1990 Molecular Reprod. & Developm. 26 47 Subsequently, the usual organules differentiate in the cytoplasm.
1997 Jrnl. Invertebr. Pathol. 69 14 The epithelial cells appear to be undergoing an active secretory phase; in several regions they also show discontinuities and organule and surface changes.
2. † a. T. H. Huxley's name for: a sensory receptor cell. Also sense organule. Obsolete. rare.

1966 P. A. Lawrence in Jrnl. Cell Sci. 1 475 The German word Kleinorgan (Henke, 1953) which is applied to small integumental structures such as scales, bristles, hairs, chemosensilla, campaniform sensilla, dermal glands, oenocytes and the like, has no equivalent in English and there is a clear need for a comparable term. Accordingly, the term organule is proposed.
1976 Philos. Trans. (Royal Soc.) B. 274 581 The control of polarity orientation amongst other sensory organules of the insect integument.
1977 Tissue & Cell 9 711/1 Especially intriguing morphogenetic capacities are shown by certain small clusters of epidermal cells which act in concert to form a cuticular structure associated with secretory or sensory cells. The general term ‘organule’ applies to all such structures, be they dermal glands or butterfly scales.
2000 Jrnl. Med. Entomol. 37 861 The bifurcation could be interpreted as an atavism, indicating that these sensilla are compound organules phylogenetically derived from two sensilla each, with fewer neurons and enveloping cells.
