One of the small bones or particles of calcareous or other hard substance in the internal ear of vertebrates, and in the auditory organs of many invertebrates; an ear stone. Collectively, the otoliths are called ear sand and otoconite.
Structure of the inner ear of fish, made of calcium carbonate. Also called "ear bone" or "ear stone". Otoliths are used to determine the age of fish: annual rings can be observed and counted. Daily increments are visible as well on larval otoliths.
a particle of calcium carbonate embedded in the otolithic membrane; it functions in maintaining static equilibrium
otikos = of the ear (G. ous = the ear) + lithos = stone; cystals embedded in mucus of maculae of utricle and saccule.
(oh´ tuh lith) [Gk. otikos: ear + lithos: stone[ • Structures in the vertebrate vestibular apparatus that mechanically stimulate hair cells when the head moves or changes position.
Greek otos = ear, and lithos = stone; hence, calcareous particles in the utricle and saccule of the membranous labyrinth.
Small dense crystalline structures, made up of calcium carbonate, that induce a shearing force on hair cells in response to linear acceleration.
oh-tow-leeth Any of the small particles of calcium carbonate in the inner ear of vertebrates, involved in sensing gravity and movement.
a bone located in a fish's skull and is analogous to the human earbone
A particle of calcium carbonate found in the inner ear of vertebrates and involved in sensory perception.
A bone-like structure found in the inner ear of many species of fish that allows scientists to estimate age.
a small ball of bony material found in a fish’s inner ear. A fish’s three pairs of otoliths seem to help it keep its balance in the water. Growth bands in otoliths also contain important clues about a fish’s age.
O-toe-lith Calcium carbonate granules in the vestibule of the inner ear whose movements provide information on changes in velocity. 655
Crystalline calcium_carbonate structures within the inner ear of fish. These structures have distinctive shapes, sizes, and internal and surface features that can be used for age determination and species identification.
Ear bone of a fish; they often show seasonal or annual "rings" that can be used to determine age.
calcium carbonate concretion in the vestibular portion of inner ear, involved with balance. (More? Organs of Audition and Equilibrium | Senses Notes)
A small calcareous concretion located in the inner ear which plays a part in the mechanism or orientation.
calcareous particles in the inner ear involved with balance and perception of acceleration
Gr. "ear-stone" (?). Minute calcium carbonate "stones" associated with neuromast organs in the labyrinth. The "stones" deform the villi of the hair cells in response to changes in orientation in the gravity field. See The Ear.
An otolith (or otoconium) is one of the small particles of calcium carbonate in the saccule or utricle of the inner ear. Pressure of the otoliths on the hair cells of the macula provide sensory inputs about acceleration and gravity.
One of three (paired) structures in the inner ears of fishes that are formed from alternating layers of high and low-density calcium carbonate. These calcium rings can be used to estimate the approximate age of a fish.
An otolith, (oto-, ear + lithos, a stone) or otoconium is a structure in the saccule or utricle of the inner ear. It is comprised of a combination of a gelatinous matrix and calcium carbonate crystals. Otolith crystals are relatively dense and heavy - they are connected to the rest of the body by the sensory processes of the macular cells.
