Adrenergic mechanisms in the rabbit ear artery. A review.

A number of factors which have been implicated in the response of the rabbit ear artery to adrenergic agents and stionstriction in the arterial smooth muscle; (b) the interrelationship between the intramural distribution of sympathetic nerves and muscle, and the influence of uptake and enzymic inactivation on the response to norepinephrine, and (c) the influence of presynaptic adrenergic and cholinergic receptors on the rwsponse to sympathetic nerve stimulation.
