The characteristics of 47 non-medullated and 54 medullated fibres arising from aortic arches of 6 hypertensive rabbits have been investigated. The threshold for activation of the aortic C-fibres lay between 78 and 190 (mean 122) mmHg. The threshold for activation of 54 medullated aortic baroreceptors in the same animals was from 70 to 140 (mean 109) mmHg. At the awake mean arterial blood pressure (MABP) of these hypertensive rabbits (143 mmHg) all the medullated fibres were active as were 78… CONTINUE READING
