Relaxation of intestinal smooth m uscle by sympathetic innervation is caused by activation of A) $\beta$₁ receptors on the nerves B) $\beta$₂ receptors on the muscle C) $\alpha$₁ receptors on the muscle D) Cholinergic receptors on the muscle E) $\alpha$₂ receptors on the muscle

Question

Quizplus · Accepted Answer

The relaxation of intestinal smooth muscle by sympathetic innervation is primarily mediated through the activation of $\beta_2$ adrenergic receptors on the muscle cells. These receptors, when activated, lead to relaxation of the smooth muscle.
