It selectively activates alpha2 receptors in the central nervous system (CNS) adrenergic blocker, clonidine's action occurs in the CNS. B. It causes peripheral activation of alpha1 and alpha2 receptors. C. It depletes sympathetic neurons of norepinephrine. D. It directly blocks alpha and beta receptors in the periphery -Clonidine is an alpha2-adrenergic agonis...

Subcutaneous administration Basically the same properties as IM administration. Adrenergic receptors Are receptors that mediate responses to epinephrine (adrenaline) and norepinephrine. Cholinergic receptors Receptors that mediate responses to acetylcholine. Types of Cholinergic receptors nicotinicN, nicotinicM, and muscarinic receptors. Types of adrenergic receptors alpha1, alpha2, beta1, and beta2 receptors. Activation of Nicotinic N receptors Promotes ganglionic...

What body parts/locations does the stimulation of the muscarinic receptor subtype affect? (8) What are the effects of simulation of dopamine receptors? What are cholinesterase inhibitors? What is selectivity vs non-selectivity? What are adverse effects of alpha blockers? (5) Sodium retention and increased blood volume (d/t decreased BP, body tries to compensate by retaining sodium & water to raise BP - usually diuretic is given as well in this case) What is ...
