Surf excel liquid detergent price The receptors reacting to vibration, little bodies of Fatera-Pachini are. They are on sites of the skin which have been not covered with hair: in a mucous membrane, in a fatty fabric of hypodermics, in articulate bags and sinews also concern very quickly adapting receptors. Little bodies of Fatera-Pachini are detectors of short mechanical influences. The sensation of vibration arises at repeated irritation of a capsule of a little body of Fatera-Pachini. Last is deformed and operates on the nervous termination located in a core of a little body of Fatera-Pachini. Thus in the nervous termination there is a generating potential. The little body of Fatera-Pachini reacts to high-frequency enough irritation - 40 1000 Hz with the maximum sensitivity of 300 Hz. Above 500 Hz the sensation of pressure or decreases, or completely disappears. Besides air conductivity exists also bone (skull bones). The sensation of a sound arises and when the vibrating subject, for example a tuning fork, put to сосцевидному to a shoot of a temporal bone then sound fluctuations extend directly through a skull. Definition of bone conductivity of a sound allows to reveal a pathology of an internal ear. Motility of a gastroenteric path - one of the factors limiting speed and completeness всасывания of medical products.
