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.

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 ...

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 ...

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.

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.

The effect of inertial force acceleration on the otolithic membrane
IEEE Engineering in Medicine and Biology Magazine, 2000The purpose of this study was to examine the response of the otolithic membrane to vertical (Gz-axis) linear acceleration force. By collecting subjective sensation and objective data (vestibulo-spinal reflex response), our study investigated the consequence of exposing these sensory membranes to linear acceleration shear forces. We compared the pilot's

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

Motion of the otolithic membrane in the bullfrog sacculus
AIP Conference Proceedings, 2015Accessory structures that overlie the sensory epithelia of the various inner ear organs play an important role in the transduction of mechanical perturbations by the underlying hair cells. It imposes a load (mass, offset in position) on individual hair bundles and is the medium that mechanically couples multiple hair bundles.

Ultrastructural changes of statoconia after segmentation of the otolithic membrane
Hearing Research, 1987The chick vestibule transformed from a homogeneous epithelial layer at day 2 (stage 15) into a pseudo-stratified epithelial layer at day 4 (stage 24). The apical columnal appearance of sensory cells was evident by day 6 (stage 29). In the supporting cells of the saccule and utricle large rough endoplasmic reticulum cisterns filled with material similar

Surface View of the Guinea Pig Otolithic Membrane
Practica Oto-Rhino-Laryngologica, 2010Providing 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 ...
