repr. Gr. στατό-ς standing, used (mainly as virtual combining form of static, statics) in scientific words, chiefly Biol., as ˌstato-aˈcoustic a. Anat., pertaining to the senses or faculties of both equilibration and hearing; spec. the epithet of the eighth cranial nerve (the vestibulo-cochlear nerve). ˈstatoblast, a reproductive gemmule developed in some Polyzoa and Sponges and liberated after the death of the parent organism; hence ˌstatoˈblastic a. ˈstatocone [Gr. κονία dust], each of the large number of granules in the statocyst of some animals, similar to a statolith, but smaller; also, an otolith in a vertebrate; also statoˈconia n. pl. ˈstatocyst, -cyte, each of the cells or cysts containing statoliths. ˌstatoˈgenesis, staˈtogeny, the (theoretical) origin of organic structures from static conditions (opposed to kinetogenesis); hence ˌstatogeˈnetic a., ˌstatogeˈnetically adv. ˈstatolith, a calcareous body found in some locomotor invertebrates, and supposed to be a means of orientation; hence applied to a starch-grain found in the cell-sap of some plant-cells (see quots.); also, an otolith in a vertebrate. staˈtometer, an instrument for measuring the degree of exophthalmos (Syd. Soc. Lex. 1898). ˈstatoplast (see quot.). ˈstatorhabd [Gr. ῥάβδος rod] = tentaculocyst. ˈstatoscope, a form of aneroid barometer adapted for recording minute variations of atmospheric pressure. ˈstatosphere, ˈstatospore (see quots.).
1958Gray's Anat. (ed. 32) 144 The ganglia of the vagus, glossopharyngeal, *stato-acoustic (in part), facial and trigeminal nerves are derived from the ganglion-crest, but they migrate ventrally and soon come to lie on the ventrilateral aspect of the hind-brain. 1964J. Z.

1963Biol. Bull. CXXV. 441 In the labyrinth of teleosts there are generally three large statoliths... Most other vertebrates, however, have otolith masses consisting of a very great number of small *statoconia held more or less firmly together by an organic gel. 1979Nature 30 Aug. 832/1 Inner ear sensory surfaces from the Pacific herring..were prepared... After removal of the statoconia (otoliths) the tissues were dehydrated. 1980Gray's Anat. (ed. 36) 1205/1 The gelatinous mass into which the cilia project is flatter and is termed an otolithic membrane.., because it contains numerous minute crystalline bodies called otoliths, otoconia, or statoconia.
