Exempel på hur man kan använda OTOLITH i en mening

• In humans the vestibular nerve transmits sensory information from vestibular hair cells located in the two otolith organs (the utricle and the saccule) and the three semicircular canals via the vestibular ganglion of Scarpa.
• The three semicircular canals, which recognize accelerations in pitch, yaw, and roll, are stimulated by angular accelerations; while the otolith organs, the saccule and utricle, are stimulated by linear accelerations.
• This vesicle, together with a bag with an otolith (sacculum containing the otolith sagitta), itself communicating to the lagena (containing the otolith asteriscus), is in fact unique among vertebrates, completely independent of the other organs; it is neither connected to the labyrinth to which only one otolith bag (the utriculus containing the otolith lapillus) is attached, nor is it connected to the swim bladder (except in embryos) of which it has the same histological structure, nor is it therefore related to the pharynx.
• Fishes often have a single large crystal called an otolith, but otoconia from higher vertebrates have numerous crystals, and each apparently single crystal in fact has multiple crystallites that are composed of organic and inorganic components.
• In the anterior part (the head), there is a statocyst or otolith: a gravito-sensor that allows the worm to orient itself in space and to show a negative geotropism (a mechanical stimulus against the wall of a tube containing worms triggers their active dive to the bottom of the tube).
• The larvae of ascidians (sea squirts) contain a pair of sensory pigment cells known as the otolith and ocellus.
• Recent otolith microchemistry analysis suggests that Australian whitebait are a semi-anadromous, or an estuarine dependant marine species, as residence in pure freshwater does not appear to occur during the life-cycle.
• About the size of a pencil eraser, the vestibular system contains two distinct structures: the semicircular canals, which detect changes in angular acceleration, and the otolith organs (the utricle and the saccule), which detect changes in linear acceleration and gravity.
• Callionymus vyali Carolin, Bajpai, Maurya & Schwarzhans, 2022 (otolith based fossil species, Burdigalian).
• One of these otolith taxa, the mud-dwelling Pythonichthys arkansasensis, appears to have thrived in the aftermath of the K-Pg extinction, based on its abundance.
• Cirripectes biconvexus, an otolith based fossil species from the Burdigalian (Miocene) of southwestern India (Quilon Formation) is probably the earliest record of this genus.
• While Gluteus minimus has been interpreted as either a fish tooth or a brachiopod, it cannot be confidently placed in any phylum, and more recent 3D analyses suggest it may be an otolith or statolith from a Devonian free-swimming animal rather than an entire organism or the shell of an organism.
• Jaydia? quilonica Carolin, Bajpai, Maurya & Schwarzhans, 2022 (otolith based fossil species, Burdigalian).
• Canalithiasis is characterized by a dislodged otolith particle, called otoconia, that floats in the fluid in one of the three vestibular canals and cause the feeling of dizziness with vision disturbances.
