The Mechanics of the Growing Semicircular Canal [PDF]

Journal of Experimental Biology, 1973
ABSTRACT The motion of the endolymph in the semicircular canal is described with the aid of a linear second-order system, comprising the applied angular acceleration and the linear displacement, the linear velocity and the linear acceleration of the endolymph.

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.

Technique of Multi-Planar CT Image Reconstruction for the Evaluation of Superior Semicircular Canal Dehiscence Syndrome

Philippine Journal of Otolaryngology Head and Neck Surgery, 2011
Superior semicircular canal dehiscence (SSCD) syndrome is an unusual cause of vertigo that was first identified by Minor in 1998. The patients initially described by Minor presented with vertigo, oscillopsia, and/or dysequilibrium related to sound ...

Design and analysis of HSC-BPPV diagnostic maneuver based on virtual simulation

Frontiers in Neurology, 2023
BackgroundThe preferred supine roll test for the diagnosis of horizontal semicircular canal BPPV has several disadvantages, including difficulty in locating the affected ear, inconsistent nystagmus performance on repeated testing, and lack of a typical ...

Cancer therapy‐induced ototoxicity: Current challenges and emerging management strategies

Animal Models and Experimental Medicine, EarlyView.
This review comprehensively examines the key risk factors for cancer therapy‐induced ototoxicity, including cumulative drug dose, genetic susceptibility, and combined treatment regimens. It highlights current challenges in ototoxicity monitoring, such as insufficient timeliness and limited clinical adoption, and advocates for standardized auditory ...

Inner ear morphology in the Atlantic molly Poecilia mexicana [PDF]

, 2011
Fishes show an amazing diversity in hearing abilities, inner ear structures, and otolith morphology. Inner ear morphology, however, has not yet been investigated in detail in any member of the diverse order Cyprinodontiformes.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Statistical shape modeling of the human inner ear through micro‐computed tomography imaging

The Anatomical Record, EarlyView.
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Semicircular canals in Anolis lizards: ecomorphological convergence and ecomorph affinities of fossil species [PDF]

Royal Society Open Science, 2017
Anolis lizards are a model system for the study of adaptive radiation and convergent evolution. Greater Antillean anoles have repeatedly evolved six similar forms or ecomorphs: crown-giant, grass-bush, twig, trunk, trunk-crown and trunk-ground.

Optimizing the vertebrate vestibular semicircular canal: could we balance any better? [PDF]

, 2004
The fluid-filled semicircular canals (SCCs) of the vestibular system are used by all vertebrates to sense angular rotation. Despite masses spanning seven decades, all mammalian SCCs are nearly the same size.
