The cardiovascular centre, or cardiovascular center, is part of the medulla oblongata of the brainstem. [1] [2] Normally, the heart beats without nervous control.In some situations, such as exercise, and major trauma, the cardiovascular centre is responsible for altering heart rate.
The medulla contains the cardiovascular center, the respiratory center, vomiting and vasomotor centers, responsible for the autonomic functions of breathing, heart rate and blood pressure as well as the sleep–wake cycle. [2] "Medulla" is from Latin, ‘pith or marrow’.
The vasomotor center (VMC) is a portion of the medulla oblongata. Together with the cardiovascular center and respiratory center , it regulates blood pressure . [ 1 ] It also has a more minor role in other homeostatic processes.
The medulla oblongata, often just referred to as the medulla, is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. [11]: 1121 The medulla contains the cardiac, dorsal and ventral respiratory groups, and vasomotor centres, dealing with heart rate, breathing and blood pressure.

The ventrolateral medulla, part of the medulla oblongata of the brainstem, plays a major role in regulating arterial blood pressure and breathing. It regulates blood pressure by regulating the activity of the sympathetic nerves that target the heart and peripheral blood vessels .

The aortic bodies give feedback to the medulla oblongata, specifically to the dorsal respiratory group, via the afferent branches of the vagus nerve (cranial nerve X). [ 1 ] [ 3 ] The medulla oblongata, in turn, regulates breathing and blood pressure .
