Secretion of endolymph by semicircular canals of the shark

, 1988
The semicircular canals of the vestibular labyrinth of the dogfish shark, Squalus acanthias, may serve as a simple in vitro system for the study of the ionic transport mechanisms involved in endolymph formation.

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

The Anatomical Record, Volume 309, Issue 11, Page 3123-3136, November 2026.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Semicircular Pathways

, 2018
Once the semicircular canal fibers leave the peripheral labyrinth, they synapse in the ipsilateral vestibular nucleus, and then ascend to the ocular motor nuclei.

Color‐Bar Bedsheet: Affordable Assistive Tool for Dix‐Hallpike Test in Primary Care

Journal of General and Family Medicine, Volume 27, Issue 6, November 2026.
ABSTRACT Background Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo encountered in general practice. The definitive diagnosis relies on the Dix‐Hallpike test (DHT), which remains underperformed in primary care due to limited training and unfamiliarity among general practitioners.

Spontaneous Nystagmus in Benign Paroxysmal Positional Vertigo: Is It A New Sign?

Acta Medica Iranica, 2013
Benign Paroxysmal Positional Vertigo (BPPV) is a condition that indicates a benign inner ear disorder. It is generally believed that BPPV is due to the dislodged otoconial particles from otolith organs and unusual collection of them within any of ...

Uncovering the Genetic Landscape of Pediatric Hearing Loss Along the Texas–Mexico Border

Clinical Genetics, Volume 110, Issue 5, Page 627-636, November 2026.
Project GIVE provided evaluations and genome sequencing to 23 children with hearing loss along the Texas–Mexico border. Seventy percent received a molecular diagnosis and 56% of those diagnosed had changes to medical management. In this region, underdiagnosis of genetic hearing loss is due to care barriers rather than lower genetic burden.

Modeling of patient-specific three semicircular canals

, 2016
The semicircular canals (SCC) are fluid-filled inner ear structures designed to detect circular or angular motion. In this study we modeled three-dimensional biomechanical model of SCC and compared results with real patient case for the Benign Paroxysmal
