NR546 Quiz reviews - Weekly Quiz review Propagation of an action potential to the axon terminal is mediated by voltage-sensitive sodium channels. Influx of sodium through voltage-sensitive sodium channels at the axon terminal leads to opening of voltage-sensitive calcium channels, also at the axon terminal. Influx of calcium through the open voltage sensitive calcium channels leads to docking of synaptic vesicles and secretion of neurotransmitter into the synapse.Agonists cause ligand-gate...

The flow of neurotransmitter from postsynaptic neuron to presynaptic neuron 3. Use the following CYP450 table to hypothesize drug interactions and their clinical significance for a patient on clozapine who carbamazepine, a mood stabilizer?

NSG 531 Advanced Pharmacology Exam 3 Questions With Correct Answers Latest Updated 2024/2025 Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean that the...
