The Otolithic Membrane Mediates Otolith Organization
The FASEB Journal, 2016Otoconia are small biocrystals that link mechanical forces to the sensory hair cells in the mammalian utricle and saccule, a process essential for sensing linear acceleration and gravity as well as maintaining bodily balance. In fish, structurally similar otoliths mediate both balance and hearing.

Improved preservation of the otolithic membranes
Proceedings, annual meeting, Electron Microscopy Society of America, 1987Any explanation of vestibular micromechanics must include the roles of the otolithic and cupular membranes. However, micromechanical models of vestibular function have been hampered by unresolved questions about the microarchitectures of these membranes and their connections to stereocilia and supporting cells.

A finite element model of the otolith membrane
Computers in Biology and Medicine, 1977Abstract This paper describes a finite element model of the otolith membrane. The system of differential equations governing the displacement of the membrane is expressed in the equivalent variational form. The region occupied by the membrane is divided into triangles and the computer is used to determine the linear combination of the functions ...

Ultrastructure of the Otoliths and Otolithic Membrane of the Macula Utriculi in the Guinea PIG
Acta Oto-Laryngologica, 1971The fine structure of the otoliths and oto-lithic membrane of the macula utriculi in the guinea pig has been studied. It has been confirmed that it adopts a wavy arrangement, being formed of two zones of different electronic densiiy, one marginal and the other medial. Of these zones the former is composed of fibres and an interfibrillar substance.

Journal of Morphology, 1980
AbstractThe sagitta otolithic membrane of Fundulus heteroclitus consists of two different zones. A structured zone (gelatinous layer), which usually exhibits a reticulated or honeycomb‐like architecture, is composed of tightly arranged fibrous material and covers only the sensory region of the macula.

Otolithic Membranes of the Saccule and Utricle in Man
Science, 1967The otolithic membranes of the human saccule and utricle can be prepared as whole mounts or surface specimens for microscopic examination. They are not simple, homogeneous, gelatinous structures as heretofore described. Instead, each shows a definite and characteristic fibrillar design, which appears to be correlated with the known cytoarchitectural ...

Evolution of Otolithic Membrane. Structure of Otolithic Membrane in Amphibians and Reptilians
Journal of Evolutionary Biochemistry and Physiology, 2004Otolithic membrane of utricles, saccules, and lagena of amphibians (Bufo bufo, Xenopus laevis, Rana temporaria) and reptiles (Teratoscincus scincus, Agama sanguinolenta, Ophisaurus apodus, Caiman crocodilus) were studied using light and scanning electron microscopy.

A computer simulation of the otolith membrane
Computers in Biology and Medicine, 1973Abstract This paper describes a model of the otolith membrane of the macula utriculi. A thin elastic membrane with a fixed boundary closely matching the shape of the otolith membrane in man is used as the model. The distributed loading of the membrane reflects the characteristic otokonial ridge which together with the corresponding thickening in the

Surface View of the Guinea Pig Otolithic Membrane
ORL, 1970Providing direct three-dimensional visualization, scanning electron microscopy gives more detailed information about shape, surface and arrangement pattern of the statoconia than all previous methods. Scanning electron microscopic surface views of the guinea pig otolithic membrane are presented, and the relevance of the results is discussed with ...

Models of otolithic membrane–hair cell bundle interaction
Hearing Research, 2002Transformation of the mechanical input in the chain: acceleration of otolithic membrane (OM)-displacement of the OM gel layer-deflection of hair cell bundle (HCB)-formation of the temporal pattern of polarization was studied using simplified analytical models of these stages of conversion of mechanical stimulus into the HCB electrical response.
