As demonstrated in acute experiments on cats, stimulation of the mechanoreceptors of the bladder and rectum caused vasodilation in the extremities in response to weaker stimuli and vasoconstriction in response to stronger. Vessels of posterior extremities reacted to weaker stimuli than did those of the anterior. Sympathetic impulsation controlling the vascular tone of posterior extremities was inhibited in response to weaker stimulation of mechanoceptors of the bladder and of rectum and increased in response to stronger stimuli. The difference between the effects of stimulation of the bladder and rectum was that, to obtain equal reactions, stimuli of lesser intensity were required in the case of the bladder than of the rectum. In the formation of blood pressure reactions in response to stimulation of the vesical and recral mechanoceptors the skeletal muscle vessels did not occupy any exclusive position among the vessels of the various parts of the body. |
