FLASHCARD QUESTION
Front
Where are neurotransmitters synthesized and stored?
Back
Neurotransmitters are synthesized and stored in vesicles of the presynaptic neuron.
2.
FLASHCARD QUESTION
Front
What happens when an action potential reaches the presynaptic terminal?
Back
Voltage-gated Ca2+ channels open.
3.
FLASHCARD QUESTION
Front
What is the role of Ca2+ ions in neurotransmitter release?
Back
Ca2+ ions flow in, causing vesicles containing neurotransmitter molecules to move and fuse with the presynaptic membrane.
4.
FLASHCARD QUESTION
Front
How is neurotransmitter released into the synaptic cleft?
Back
Neurotransmitter is released from the presynaptic neuron into the synaptic cleft via exocytosis.
5.
FLASHCARD QUESTION
Front
What happens after neurotransmitter is released into the synaptic cleft?
Back
Neurotransmitter binds to receptor molecules on the postsynaptic membrane.
6.
FLASHCARD QUESTION
Front
What is the effect of neurotransmitter binding on the postsynaptic membrane?
Back
It causes the opening of postsynaptic ion channels for Na+ ions, allowing Na+ ions to enter.
7.
FLASHCARD QUESTION
Front
What is the result of Na+ ions entering the postsynaptic neuron?
Back
The entry of Na+ ions causes changes in the voltage of the membrane, known as depolarization.
