A Medicare Part D prescription drug plan could potentially cover your use of insulin pens and other diabetic supplies such as syringes. Medicare Part D plans are sold by private insurers, so the exact medical supplies, prescriptions and other health care services they cover will vary based on your Part D plan provider.
adrenergic receptors. Definition: reactive components of effector tissues, most of which are innervated by adrenergic postganglionic fibers of the sympathetic nervous system.
The classical site of adrenergic receptors is the sympathetic neuroeffector junction. As in the case of cholinergic receptors, however, adrenergic receptors may exist on the cells of effector organs, even in the absence of sympathetic innervation.In other words, not necessarily all adrenergic receptors are innervated.holinergic, receptors mediate the actions of acetylcholine (ACh). Other choline esters such as methacholine (MecholylÂ®) or carbamylcholine (CarbacholÂ®) mimic the actions of ACh at the same receptors. Cholinergic receptors are subdivided into: 1  muscarinic.
