[Arterial pressure responses to stretch and contraction of the gastrocnemius during stepwise interruption of its connections to the body].
In anesthetized cats, the pressoreaction of arterial pressure to stretch with weight of 3--4 kg and to contraction of the m. gastrocnemius due to direct 6--10--threshold electrical stimulation 50/sec, occurred due to reflex from the muscle receptors in 92--93%. 80--82% of the reaction was due to the afferents of the ischiatic nerve, and 11--12% to the afferents of vascular plexus. 7--8% were due to the blood outflow from the muscle and was unrelated to the stimulation.
