An action potential arriving at the presynaptic terminal causes what to occur? Voltage-gated calcium ion channels open, and calcium ions diffuse into the cell.
- When an action potential enters the presynaptic terminal which types of voltage-gated channels open?

- When an action potential arrives at the axon terminal in the presynaptic terminal membrane quizlet?
- What happens when the action potential reaches the terminal button quizlet?
- Which of the following occurs when an action potential arrives at the presynaptic terminal quizlet?
- Which of the following occurs when an action potential arrives at the presynaptic terminal?
- What occurs when an action potential arrives at the end of an axon?

- What occurs when an action potential arrives at the presynaptic terminal?
When an action potential enters the presynaptic terminal which types of voltage-gated channels open?
-gated Ca2+ channels.
When an action potential reaches the presynaptic terminal quizlet?
What events occur in the presynaptic terminal when an action potential reaches the presynaptic terminal? The binding of a neurotransmitter to a receptor on the postsynaptic membrane causes the associated membrane channel to change shape, allowing it to open.
When an action potential arrives at the axon terminal in the presynaptic terminal membrane quizlet?
When an action potential arrives at the axon terminal, the voltage-gated calcium channels at the terminal... Open; the influx of calcium causes the vesicles to fuse with the presynaptic membrane and release a neurotransmitter into the synaptic cleft.
Action Potential In The Neuron
What happens when the action potential reaches the terminal button quizlet?
What happens when the action potential reaches the terminal button? The signal causes the vesicles to release neurotransmitters. Chemical substances that carry messages directly from one neuron to the next are called: neurotransmitters.
Which of the following occurs when an action potential arrives at the presynaptic terminal quizlet?
Acetylcholine is actively transported from the presynaptic membrane to the postsynaptic membrane. Which of the following occurs when an action potential arrives at the presynaptic terminal? Synaptic vessels migrate to the plasma membrane and release acetylcholine.
Which of the following occurs when an action potential arrives at the presynaptic terminal?
When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).
2-Minute Neuroscience: Synaptic Transmission
What occurs when an action potential arrives at the end of an axon?
When the action potential reaches the end of the axon (the axon terminal), it causes neurotransmitter-containing vesicles to fuse with the membrane, releasing neurotransmitter molecules into the synaptic cleft (space between neurons).
What happens as a result of ion flow at a presynaptic terminal quizlet?
What happens as a result of ion flow at a presynaptic terminal? Synaptic vesicles migrate to the plasma membrane and release acetylcholine.
2-Minute Neuroscience: Neurotransmitter Release
What does the arrival of the action potential at the axon terminal of a pre synaptic neuron trigger?
Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).
What occurs when an action potential arrives at the presynaptic terminal?
When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).
