[Elastic properties of the atria and characteristics of atrial mechanoreceptors].
Acute experiments were conducted on cats; a recording was made of the sum total activity of the mechanoreceptors of the right auricle, pressure in the auricle and its extension. It was demonstrated that extensibility of the auricles sharpely decreased with the pressure of over 5mm Hg, whereas with high pressure there was seen a marked increase in the sensitivity of the mechanoreceptors to the auricular extension. Due to this linear relationship between the pressure in the auricle and the activity of the mechanoreceptors was etained this permitting them to supply information to the rcentral nervous system concerning the auricular pressur with its change within a wide range.
