The SA node is also responsive to epinephrine,a hormone secreted by the adrenal medulla. Explain why the onset of the effect of the hormone is so much slower than the onset of the effect from sympathetic nerve stimulation and yet the effect of the hormone lasts much longer than the effect of nerve stimulation.arrow_forward
