Which statement best describes how neurotransmitter is released from a neuron? Na+ channels open, and neurotransmitter diffuses out of the neuron through the open channels. Ca+ channels open, and neurotransmitter diffuses out of the neuron through the open channels. K+ channels open, and neurotransmitter diffuses out of the neuron through the open channels. The neurotransmitter is engulfed by the presynaptic neuron. The action potential arrives at the synaptic terminal, which results in synaptic vesicles fusing with the plasma membrane to release neurotransmitter into the synapse.

When an action potential reaches the axon terminal, most neurons release a chemical called a neurotransmitter. Which of the following statements regarding this process is INCORRECT? A. Ca2+ influx into the axon terminal results in fusion of the membranes of the synaptic vesicle and the neuronal cell membrane. B. Ca2+ influx into the axon terminal occurs by active transport of Ca2+ ions against its concentration gradient across the cell membrane. C. The process by which neurotransmitter release occurs from the axon terminal is exocytosis. D. An action potential reaching the axon terminal causes the opening of voltage-gated Ca2+ channels. E. Neurotransmitters are stored in synaptic vesicles in the axon terminal of the neuron.

Which of the following statements best describes saltatory conduction? a. It inhibits direct neurotransmitter release. b. It transmits the action potential at the nodes of Ranvier and thus speeds up impulses on myelinated axons. c. It increases neurotransmitter release at the presynaptic membrane. d. It decreases neurotransmitter uptake at chemically gated postsynaptic channels. It removes neurotransmitters from the synaptic cleft.
