When heart rate increases, this due to stimulation of ——- of the heart
a. Nicotinic receptors
b. Alpha receptor
c. Beta receptors
d. Muscarinic receptors
Beta receptors
p.499 - The heart rate increases considerably more under the influence of thyroid hormone than would be expected from the increase in cardiac output. Therefore, thyroid hormone seems to have a direct effect on the excitability of the heart, which in turn increases the heart rate e sabi si beta adrenergic daw is nagsstimulate sa thyroid
