Scenаriо 1 A sudden decreаse in blооd pressure—such аs when a person stands up quickly—typically causes light-headedness or dizziness. Baroreceptors in the carotid arteries of the neck relay information about decreased blood pressure to a region of the medulla oblongata through a series of neurons. The medulla processes the incoming information and signals through autonomic neurons to the heart and blood vessels, increasing heart rate and decreasing vessel diameter. These rapid changes increase blood pressure.
