Karten in diesem Stapel (18)
- 1What is the sympathetic nervous system related to?Flight or fight
- 2What is, by analogy, the name given to the parasympathetic system?Rest or digest
- 3What are the roles of the parasympathetic and sympathetic nervous systems?PS - house keeping
S- emergency
Although there is an overlap - 4Where do the PS and S systems originate?PS - craniosacral
S - thoracolumbar - 5What is the general design of an autonomic efferent pathway?2-neuron chain from CNS to effector organ, synapse near the CNS or the effector organ depending on the system
- 6In the autonomic nervous system, what is the neurotrasmitter involved at the ganglionic level?A
- 7In the autonomic nervous system, what is the neurotrasmitter involved at the effector organ level?Acetylcholine for parasympathetic and noradrenaline for sympathetic
- 8What type of receptor does the parasympathetic system act on at the effector organ level ?Cholinergic muscarinic
- 9What type of receptor does the sympathetic system act on at the effector organ level ?Alpha or Beta Adrenergic
- 10What type of muscarinic receptor is mainly found in the heart?M2
- 11What type of muscarinic receptor is mainly found in the smooth muscles and the secreting glands?M3
- 12The activation of what type(s) of adrenergic receptor leads to a vasoconstriction, by contraction of the vascular smooth muscles?Alpha 1 & alpha 2
- 13The activation of what type(s) of adrenergic receptor leads to an increased contractility of the myocardium?Beta 1 and beta 2
- 14Phenyleprine is an activator of the sympathetic system, a sympathomimetic, acting almost exclusively on alpha 1 adrenoceptors. What cardiovascular effect do you then expect from an injection of phenylephrine?Vasoconstriction
- 15Dobutamine is an activator of the sympathetic system, a sympathomimetic, acting almost exclusively on beta 1 adrenoceptors. What predominent cardiovascular effect do you then expect from an injection of dobutamine?Increased heart rate and contractility of the myocardium
- 16Atenolol is an inhibitor of the sympathetic system, a sympatholytiic, acting almost exclusivelyby blockade of the beta 1 adrenoceptors. What predominent cardiovascular effect do you then expect from an injection of atenolol?Decreased heart rate and contractility of the myocardium
- 17Atropine is an inhibitor of the parasympathetic system, a parasympatholytiic, blocking muscarinic receptors. What effects on the digestive system do you then expect from an injection of atropine?Decreased GI transit and GI secretions
- 18What type of drug, acting on the ANS, would you use to induce urination (contraction of smooth muscles in the bladder)?A parasympathomimetic
