adrenergic blocking agent
adrenergic blocking agent n.
A compound that selectively inhibits responses to sympathetic adrenergic nerve impulses and to adrenergic amines.
- Adrenergic blockade
adrenergic blockade adrenergic blockade n. Selective inhibition by a drug of the responses of effector cells to adrenergic sympathetic nerve impulses and to adrenergic amines.
- Adrenergic fiber
adrenergic fiber adrenergic fiber n. Any of the fibers that transmit impulses to other nerve cells, smooth muscle, or gland cells by norepinephrine.
- Adrenergic neuronal blocking agent
adrenergic neuronal blocking agent adrenergic neuronal blocking agent n. A drug that blocks sympathetic nerve impulses but does not inhibit the responses of adrenergic receptors to epinephrine and other adrenergic amines.
- Adrenergic receptor
adrenergic receptor adrenergic receptor n. Any of several reactive components of effector tissues most of which are innervated by adrenergic postganglionic fibers of the sympathetic nervous system and are activated by norepinephrine, epinephrine, and various adrenergic drugs. They are classified as alpha-adrenergic receptors and beta-adrenergic receptors according to their response to various adreneregic activating and […]
