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.

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.

Fine Structure of the Otolithic Membrane in the Squirrel Monkey
Acta Oto-Laryngologica, 1969The zonal structures of the otolithic membrane in the squirrel monkey were investigated by electron microscopy, and the different morphology at the different zones was described. The definite existence of the cupular zone and subcupular zone was determined in the subhuman primates and some functional considerations were made.

Proteins of the gelatinous layer of the trout saccular otolithic membrane
Hearing Research, 1990Although the otolithic membrane is thought to play an important role in the stimulation of vestibular hair cells, little is known about its chemical composition. We analyzed proteins of the gelatinous layer of this structure from the trout saccule, a probable organ of hearing in fish, by SDS-polyacrylamide gel electrophoresis. A relatively small number

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

Cupula, Cupular Zone of Otolithic Membrane, and Tectorial Membrane in the Squirrel Monkey
Acta Oto-Laryngologica, 1969The microscopic architecture of the cupula was studied in subhuman primates. It was determined that the cupula has a honeycomb-like mesh-work and that this meshwork may contain both neutral and acid poly-saccharides, as well as mucoprotein. The nature of the contents in the space enclosed by this meshwork is not certain although the existence of a ...

Visualisation of domains in the avian tectorial and otolithic membranes with monoclonal antibodies
Hearing Research, 1994The staining patterns observed with six monoclonal antibodies (mAbs) raised in vitro against a fraction derived from the utricular macula were examined with cryosections of the auditory and vestibular organs of the avian inner ear. These antibodies revealed several distinct domains within the gelatinous membranes.

Hair-bundle stiffness dominates the elastic reactance to otolithic-membrane shear
Hearing Research, 1993Efficient transduction by acousticolateralis organs requires that a stimulus force principally deflect hair bundles, rather than flex other structural elements. Hair bundles might therefore be expected to provide a large fraction of the impedence to shear motions of otolithic membranes and other accessory structures. We measured the stiffness for shear

Incorporation Of Radioactive Calcium Into Otolithic Membranes And Middle Ear Ossicles Of The Gerbil
Acta Oto-Laryngologica, 197545CaCl2 was injected into gerbils in single or multiple doses, and the resulting radioactivity in serum, otoconial CaCO3, bone samples, and selected labyrinthine epithelium was determined by liquid scintillation spectrometry. Incorporation into both utricular and saccular otoconia occurred at the rate of 0.06-0.07 nmole Ca++ per day, corresponding to a
