Cardiovascular centre is detected by baroreceptors in the aortic sinuses or carotid sinuses, the cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker (or SA node) via sympathetic fibres (to cause faster and stronger cardiac muscle contraction) and the vagus nerve (to cause slower and less strong cardiac muscle contraction). The cardiovascular centre also increases the stroke volume of the heart (that is, the amount of blood it pumps). These two changes help to regulate the cardiac output, so that a sufficient amount of blood reaches tissue. Hormones like epinephrine and norepinephrine can affect
Cardiac neural crest cells observed when GATA6 was inactivated within vascular smooth muscle cells. GATA6 in combination with Wnt (Wnt2-GATA6) plays a role in the development of the posterior pole of the heart (the inflow tract). There is interest amongst researchers as to whether CNCCs can be used to repair human heart tissue. Heart attacks in humans are common and their rate of mortality is high. There are emergency treatments that hospitals can administer, such as angioplasty or surgery, but after that patients will likely be on medication for the long term and are more susceptible to heart attacks in the future.
