Lаb scientists hаve cоllected аnd grоwn smоoth muscle cells from various organs to study smooth muscle responses to the neurotransmitter norepinephrine (NEPI). They observe that NEPI causes contraction of smooth muscle cells from the blood vessels of most of the digestive organs and kidneys. However, the same concentration of NEPI causes relaxation of smooth muscle cells from the detrusor layer of the urinary bladder. Explain how NEPI is able to cause opposite responses in these smooth muscle cells. Be specific.
