What's the difference between otolith and statolith?
Otolith
Definition:
(n.) Alt. of Otolite
Example Sentences:

(10) The subcupular meshwork may play an important role in transmitting the shear strain of the otolithic membrane to all the ciliary bundles and may also exert an additional dampening effect to prevent unwanted vibration.
(11) The present space experiment was aimed at studying the influence of the absence of gravity stimulation on the otoliths, by comparing VOR gain and phase in space and on ground.
(12) This is in accord with neurophysiological data of otolith and somatosensory function.
(13) Otolithic contribution to this reflex has been taken into consideration.
(14) Otolith development was complete by day 18 of gestation in control mouse fetuses.
(15) These results proved that the otolithic organs are not only able to promote but also to inhibit visual function.
(16) The results of canal-otolith interaction did not depend directly on enhancement or diminishing of the otolith afferentation but rather on a relative amount of the otolith signal alterations from the two labyrinths.
(17) (A pattern in this context is an array of signals emanating from the otoliths.
(18) The responses from isolated single otolith afferent fibers were obtained to small angle sinusoidal pitch and roll tilts in anesthetized gerbils.
(19) Otolithic responses were tonic, phasic-tonic, and phasic in nature.
(20) Furthermore, the disintegration of information from the neck position receptors from those of the otolith system can lead to additional illusory positional sensations.
Statolith
Definition:
Example Sentences:
(1) On the whole, our observations indicate that the cell-extracellular matrix junction is a sine qua non for graviperception in statolith-free Chara internodal cells and we suggest that the gravireceptor is located in this region.
(2) The possibilities that other organelles function as statoliths are considered, and it is concluded not only that georeception is independent of starch grains, but further that it may not be due to statoliths at all in an ordinary sense.
(3) The occurrence of fluorite in mysid statoliths confirms the earlier interpretations based on insufficient documentation.
(4) The statolith usually occupies only a small part of the cavity of the statocyst, and it is situated in the anterior part of the statocyst.
(5) While recording from the statocyst nerve of Homarus americanus, we deflected the statolith hairs from the "rest" position they assumed after the lith was removed.
(6) The external surface of the statolith is macroscopically smooth.
(7) The statolith consists of a closely packed mass of these crystals, sometimes they are irregularly arranged, where in others they are stacked with their long axes parallel.
(8) The statolith is made up of crystalline subunits, the statoconia.
(9) Major findings from this investigation were the absence of rhopalia and statoliths in ephyrae at 150 and 200 Gy, a reduction in pulses per minute in the ephyrae at 100, 150, and 200 Gy, a reduction in ephyrae released at 150, 200, and 400 Gy, and the development of polyp monsters.
(10) X-ray diffraction patterns show that the statoliths of marine mysid crustaceans are composed of fluorite, and that this mineral is also a principal phase of the gizzard plates of some tectibranch gastropods.
(11) Larval Aplysia contain a single statolith within each statocyst; when the animals grow to a critical size, they begin producing multiple statoconia, a process that continues throughout life.
(12) Statoliths from large animals are marginally larger than those from smaller ones.
(13) The possibility that the Tullio phenomenon may be due to an abnormal excitation of the statolith organs is discussed.
(14) Morphology of the ephyrae, and statolith and rhopalia numbers were recorded using the light microscope.
(15) The single statolith has an amorphous internal structure whereas the multiple statoconia have calcification deposited on concentric layers of membrane or matrix protein.
(16) The statoliths of Sepia officinalits, Octopus vulgaris, Alloteuthis subulata and Taonius megalops have a smooth outline, but an irregular shape.
(17) The irregularity of the statolith of the lobster, Homarus americanus, probably causes a large and haphazard variation in the response of the individual statocyst receptors to body rotation.
(18) The size and outline of these large subunits do vary in different parts of the statolith.
(19) Experiments in defined media (seven basic salts mixed in deionized water) with seven species of cephalopods demonstrated clearly that there is 100% normal development of the aragonite statoliths when strontium levels were 8 mg l-1.
(20) Conversely, statoliths did not develop when strontium was absent.
