Strontium randomly substituting for calcium in fish otolith aragonite.

Analytical Chemistry, 2014
The chemistry of fish ear bones (otoliths) is used to address fundamental questions in fish ecology and fisheries science. It is assumed that strontium (Sr), the most important element used in otolith chemistry research, is bound within the aragonitic ...

The Otoliths and the Ocular Countertorsion Reflex

Archives of Otolaryngology - Head and Neck Surgery, 1971
A new photographic method for measurement of the otolithic ocular countertorsion reflex (OCR) uses a portable head frame unit to control the position of gaze and the camera. Mean ocular countertorsion of the two eyes (summed) after 50° lateral head tilt was 10.8° and 11.8° in 35 normals on right and left tilt respectively with the same large subject to

Otolith growth in fishes

Comparative Biochemistry and Physiology Part A: Physiology, 1990
Abstract 1. 1. The sagittal otoliths of teleosts rest in a groove in the base of the otic cleft resulting in restriction of growth along part of the ventral edge of the otolith. 2. 2. The rate of crystalline deposition of the otolith is low at the sulcus, increasingly higher along the sulcul surface rising to a maximum at the growing edge of ...

Evolution of Otolithic Membrane. Structure of Otolithic Membrane in Amphibians and Reptilians

Journal of Evolutionary Biochemistry and Physiology, 2004
Otolithic membrane of utricles, saccules, and lagena of amphibians (Bufo bufo, Xenopus laevis, Rana temporaria) and reptiles (Teratoscincus scincus, Agama sanguinolenta, Ophisaurus apodus, Caiman crocodilus) were studied using light and scanning electron microscopy.

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 ...

OTOLITH FUNCTIONS IN WEIGHTLESSNESS

1975
The role of the vestibular organ in the exploration of space has been studied extensively during the past two decades. Many investigators have shown that some persons experience ill effects during the transition from the normal gravity to subgravity or weightlessness.
