Human central nervous system communication at synapses is which of the following? retrograde electrical chemical ionic Question 2 2 / 2 pts Question 3 0 / 2 pts The communication between neurons at synapses is mediated by neurotransmitter molecules and is therefore chemical. Which of the following is a prominent CYP enzyme in the body and what is it responsible for? CYP3A4 - responsible for metabolism of a number of medications CYP2A4- responsible for the excretion of a number of medications CYP2C4 - responsible for the excretion of a number of medications CYP3C4 - responsible for the metabolism of a number of medications CYP 3A4 is one of the 5 most important NT which include CYP 1A2, 2D6, 2C9, 2C19, 3A4. Dosing adjustments may be required. Which of the following are involved in regulating neurotransmission via excitationsecretion coupling? Correct Answer voltage-sensitive sodium channels and voltage-sensitive calcium channels voltage-sensitive calcium channels voltage-sensitive calcium channels and voltage-sensitive potassium channels Question 4 2 / 2 pts Question 5 2 / 2 pts voltage-sensitive sodium channels 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.
