Norepinephrine binds to adrenergic receptors

WebAdrenergic Receptors As mentioned, neurons that produce and release the neurotransmitter NE are known as adrenergic neurons. NE is secreted by postganglionic neurons of the sympathetic nervous system and binds to adrenergic receptors expressed on effector cells.
