Sensory receptors Answer -Receptors convert stimuli in the environment into generator potential on sensory neuron -Sensory Neurons can be part of receptor or synapse on the receptor - different types of receptors are particularly sensitive to different, specific stimuli receptors cont. Answer -they can be free nerve endings on sensory nerves - receptors are sensitive to tissue damage and initiate sensation of pain via graded membrane potential charge -they can be specialized, independent...

Test Bank - Applied Pathophysiology for the Advanced Practice Nurse 1ST Edition Lucie By Dlugasch, Lachel Story | Complete 2023/2024. A 50-year-old man is having an acute myocardial infarction and will be administered recombinant tissue plasminogen activator (t-PA). The medication activates plasminogen in order to: A) decrease platelet adhesion. B) increase clotting time. C) promote fibrinolysis. D) promote coronary vasodilation. Ans: C Complexity: Easy Ahead: Hematopoietic System Subj...

Excitability correct answers the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization correct answers occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity correct answers the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex:...

Depolarization, Summation, and Neural Pathways Questions And Answers Depolarization - ANS-Action potential depolarizes synaptic knob Secondary Messenger - ANS-Ca enters axoplasm triggering norepi First Messenger - ANS-norepi binds to receptor site causing adenyl cyclase within the cytoplasm to catalyze the formation of cyclic AMP from ATP Second Messenger - ANS-cyclic AMP opens ion channels allowing NA to depolarize membrane Summation - ANS-Integration of EPSP's and IPSP's to reach depo...
