The vasomotor center?!
Question: The vasomotor center!?
which change in heart rate/rhythm may occur from depression of the vasomotor(blood pressure) center in the brain!?Www@Answer-Health@Com
Answers:
Vasomotor centre in the medulla has distinct vasoconstrictor and vasodilator areas!. So the response will depend on which is affected more!.Www@Answer-Health@Com
There are several centers in the body that regulate blood pressure and heart rate!. The first is the vagus nerve (cranial nerve 10)!. If this nerve is stimulate such as when a person strains to take a bowel movement, coughs, sneezes, or holds their breath against a force, this nerve gets stimulated!. It sends a direct signal to the brain to slower the heart rate!. This is when the parasympathetic nervous system kicks in!. The person could be bradycardic and could develop ectopy on an EKG monitor based on the slow rate (and accompanying hypoxia)!. This ectopy could be a PVC (premature ventricular contraction) or a PAC (premature atrial contraction)!. This is the body's way to stimulate the heart!. Another vasomotor center is the baroreceptors that are located in the aorta of the heart and carotid arteries of the neck!. When these are stimulated, the heart rate and blood pressure lower!. Once again, the same ectopy could appear on an EKG!. Those two things are the primary vasomotor centers in the body for the parasympathetic nervous system that will slow the heart rate and the blood pressure!. Hope this helps!.Www@Answer-Health@Com
