Fig. 7From: Interactions between β-adrenergic vasodilation and cervical sympathetic nerves are mediated by α2-adrenoceptors in the rat masseter muscleProposed schema for modulating effects of sympathetic systems in the blood flow in rat masseter muscle. Noradrenaline (NA) released by cervical sympathetic nerve (cSN) may induce modulation of β-adrenergic vasodilation mediated by circulating adrenaline (AD) through the post-junctional α2-adrenoceptor (α2AR) in the blood vessels in the masseter muscle. α1AR α1-Adrenoceptor, βAR β-adrenoceptorBack to article page
