Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Sympathetic nerve activity during natural stimulation of horizontal semicircular canals in humans

, 1998
We have shown that static head-down neck flexion elicits increases in muscle (MSNA) but not skin sympathetic nerve activity (SSNA) in humans. These findings suggest that stimulation of the otolith organs causes differential sympathetic outflow to ...

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Fluidmechanics of semicircular canals - revisited [PDF]

, 2018
.: In this work we find the exact solution for the flow field in a semicircular canal which is the main sensor for angular motion in the human body. When the head is rotated the inertia of the fluid in the semicircular canal leads to a deflection of ...

CHARGE Syndrome: A Narrative Review and Update on Diagnosis, Assessment and Management

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background CHARGE syndrome (CS) is a rare multisystemic genetic condition caused by a pathogenic variant in the DNA‐binding protein‐7 CHD7 gene. The condition affects the development of neural crest cells, which give rise to craniofacial structures, cranial nerves, ears, eyes and the heart, resulting in diverse and complex clinical features ...
