Binding of Epinephrine to Adrenergic Receptors Induces Tissue-Specific Responses. Epinephrine and norepinephrine were originally recognized as products of the medulla, or core, of the adrenal gland and are also known as adrenaline and noradrenaline.
Alpha 2 Receptors. Alpha 2 receptors are located on secretory terminals of some postsynaptic adrenergic neurons. When these terminals secrete norepinephrine the neurotransmitter binds with these receptors as well as with adrenergic receptors on the other side of the synapse.The presynaptic neuron's response is to decrease the amount of NE being released -- it is a negative feedback mechanism.lpha 2 Receptors.
