Does the medulla control blood pressure
WebWhen the medulla oblongata receives signals from baroreceptors and chemoreceptors, it changes the rate at which the sino-atrial node (SAN) fires (learn more about the SAN here). If blood pressure or oxygen concentration is low, the cardiovascular control centre increases the rate of SAN firing through activation of the sympathetic nervous system. Web: Although medullary control of blood pressure (BP) has been extensively studied, the contribution of critical regions, such as pressor sites in the caudal medulla and upper cervical spinal cord and the lateral tegmental field, remains controversial and underappreciated.
