Semicircular canals in squids [PDF]

open access: possibleNature, 1978
THE cephalopods and fishes are rivals as fast-moving predators and they show many parallel adaptations1. We present here evidence that in squids and cuttlefishes the statocysts possess semicircular canals, though of rather imperfect form. Animals that move quickly need to monitor angular rotation in order to allow appropriate adjustments of the eyes as

The fluid mechanics of the semicircular canals

Journal of Fluid Mechanics, 1976
A mathematical model for the unsteady fluid-dynamic response of the semicircular canals is developed. The endolymph is assumed to be an incompressible Newtonian fluid and the presence and effects of both the utricle and the cupula are specifically accounted for. A first approximate solution is obtained using a singular perturbation method.

The flow of endolymph in the semicircular canals

Physics in Medicine & Biology, 1979
The response of the receptors in the semicircular canals to rotary movement of the head is usually described in terms of an ordinary second order differential equation. There are, however, some theoretical objections to this equation and these are examined.

Orientation of the semicircular canals in rat

Brain Research, 1989
The orientation of the rat semicircular canals was determined using one of two techniques. Null point analysis was used to define physiologically the planar equations of the anterior (n = 15) and posterior canals (n = 15); equations for the horizontal canal (n = 19) were determined using an anatomical dissection technique. Canal orientation was defined

Dehiscence of the posterior semicircular canal

American Journal of Otolaryngology, 2015
Semicircular canal dehiscence (SCD) is a condition of the inner ear wherein the temporal bone adjacent to the vestibular apparatus thins or erodes completely. It has no clear epidemiological predisposing factors that have been identified to date. Its diagnosis is made difficult by a clinical presentation that often overlaps with other pathologies of ...
