Cupula, Cupular Zone of Otolithic Membrane, and Tectorial Membrane in the Squirrel Monkey

Acta Oto-Laryngologica, 1969
The 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 ...

The effect of inertial force acceleration on the otolithic membrane

IEEE Engineering in Medicine and Biology Magazine, 2000
The 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

Ultrastructural changes of statoconia after segmentation of the otolithic membrane

Hearing Research, 1987
The 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

Fine Structure of the Otolithic Membrane in the Squirrel Monkey

Acta Oto-Laryngologica, 1969
The 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.

The otolithic membrane

1983
The first reports on the otolithic membrane were done by Tenglia (1925) and Brock (1926). Wittmaak (1956) studied it in the guinea pig, rabbit and dog; Johnsson and Hawkins (1967) in the human and Lindeman (1969 a,b) in the guinea pig. Igarashi and Kanda (1969) recognized cupular zone 1 and cupular zone 2, which are called marginal and medial zones ...

Motion of the otolithic membrane in the bullfrog sacculus

AIP Conference Proceedings, 2015
Accessory 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.

Observation of the Otolithic Membrane by Low-Vacuum Scanning Electron Microscopy

ORL, 1996
Untreated specimens (i.e. not fixed, dehydrated or embedded) of the otolithic membrane from the sacculus of guinea pigs were observed at the ultrastructural level by low-vacuum scanning electron microscopy (LVSEM). This technique revealed the presence of a 15- to 20-mu m-thick layer of an amorphous substance (the supraotolithic cupula zone) on the ...

Proteins of the gelatinous layer of the trout saccular otolithic membrane

Hearing Research, 1990
Although 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

Hair-bundle stiffness dominates the elastic reactance to otolithic-membrane shear

Hearing Research, 1993
Efficient 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

Visualisation of domains in the avian tectorial and otolithic membranes with monoclonal antibodies

Hearing Research, 1994
The 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.
