how is adrenal medulla has ACH nicotinic receptor which are ligand-gated Na/k channeles ?
muscarinic ACH receptors are G-protein-coupled receptors.
gdupgrantepinephrine acts on alpha or beta adrenergic receptors which are all G protien receptors. muscarinic receptors are also G coupled but Acetyl choline wasnt an answer choice.
In the adrenal medulla the chromaffin cells are kinda like modified post ganglionic neurons and have nicotinic receptors.+2020-01-09T20:02:33Z
