The vestibular system , in vertebrates , is a sensory system that provides the leading contribution to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea , a part of the auditory system , it constitutes the labyrinth of the inner ear in most mammals. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canals , which indicate rotational movements ; and the otoliths , which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control eye movement ; these provide the anatomical basis of the vestibulo-ocular reflex , which is required for clear vision.
In particular, vestibular paroxysmal positional disorders of peripheral and central origin have been studied. The main criteria for differential diagnosis of these disorders have been determined. Vestibular dysfunction in canalolithiasis and cupololithiasis has been investigated clinically and histologically. Effective therapeutic and prophylactic positional maneuvers of three types have been introduced into clinical practice. They were developed taking into account the anatomical and physiological features of the vestibular system.

The ear can be divided into three parts: the outer ear , middle ear and inner ear. The inner ear is the innermost part of the ear, and houses the vestibulocochlear organs. It has two main functions:. In this article, we shall look at the anatomy of the inner ear — its position, structure, and neurovascular supply.

Три… три… Беккера словно еще раз ударило пулей, выпущенной из пистолета. Мир опять замер. Три… три… три… 238 минус 235. Разница равна трем. Он медленно потянул к себе микрофон.
Створки с шипением разъехались в стороны. Он вошел. Сьюзан стояла перед ним, промокшая, взъерошенная, в его пиджаке, накинутом на плечи. Она выглядела как первокурсница, попавшая под дождь, а он был похож на студента последнего курса, одолжившего ей свою куртку.
Она точно знала, что на такой пароль уходит меньше десяти минут. - Должно ведь быть какое-то объяснение. - Оно есть, - кивнул Стратмор. - Тебя оно не обрадует.
