Depolarization of the axon terminal membrane opens voltage-gated calcium ion channels with the calcium promoting the exocytosis of synaptic vesicles filled with ACh. ACh diffuses across the synaptic cleft and binds to receptors on the postsynaptic membrane.

What triggers the neurotransmitter to be released into the synaptic cleft?
The arrival of the nerve impulse at the presynaptic terminal stimulates the release of neurotransmitter into the synaptic gap. The binding of the neurotransmitter to receptors on the postsynaptic membranepostsynaptic membranepostsynaptic potential (PSP), a temporary change in the electric polarization of the membrane of a nerve cell (neuron). The result of chemical transmission of a nerve impulse at the synapse (neuronal junction), the postsynaptic potential can lead to the firing of a new impulse.https://www.britannica.com › science › postsynaptic-potentialpostsynaptic potential | biology - Encyclopedia Britannica stimulates the regeneration of the action potential in the postsynaptic neuron.
What triggers the release of acetylcholine into the synaptic cleft quizlet?
Calcium enters the presynaptic cell and causes the release of ACh. As a presynaptic action potential reaches the synaptic terminal, voltage-gated calcium channels open.
How are neurotransmitters released into the synapse?
Neurotransmitters are released from the axon terminal when their vesicles "fuse" with the membrane of the axon terminal, spilling the neurotransmitter into the synaptic cleftsynaptic cleftThe synaptic cleft —also called synaptic gap— is a gap between the pre- and postsynaptic cells that is about 20 nm (0.02 μ) wide. The small volume of the cleft allows neurotransmitter concentration to be raised and lowered rapidly.https://en.wikipedia.org › wiki › Chemical_synapseChemical synapse - Wikipedia.

What are the four steps of neurotransmission?
Synthesis and Storage; II. Release; III. Postsynaptic Receptors; IV. Inactivation.
What is the process of neurotransmission psychology?
When a nerve impulse (or action potential) triggers the release of neurotransmitters, these chemicals are then released into the synapse and then is taken up by the receptors on the next neuron. This process is known as neurotransmission.
What triggers synaptic vesicles to release neurotransmitter into synaptic cleft?
Calcium ion influx triggers synaptic vesicles to release neurotransmitter.
Cholinergic Synapse Mechanism
What are the steps of neurotransmitter release?
Neurotransmitter release from the presynaptic terminal consists of a series of intricate steps: 1) depolarization of the terminal membrane, 2) activation of voltage-gated Ca2+ channels, 3) Ca2+ entry, 4) a change in the conformation of docking proteins, 5) fusion of the vesicle to the plasma membrane, with subsequent ...
What are the 6 steps in neurotransmitter release and what does each step do?
1) synthesized in neuron, 2) stored in nerve terminal, 3) released in quantities sufficient to affect postsynaptic cell, 4) exogenous application mimics action, 5) mechanism for removal, 6) the presence and use of specific pharmacological blockers and agonists.

What are the steps of neurotransmission?
There are five major steps in the chemical synapses for transmission of signals: (1) synthesis of neurotransmitter, (2) neurotransmitter storage in synaptic vesicle (quanta), (3) release of the neurotransmitter to the synaptic space, (4) binding of the neurotransmitter to the specific receptors on postsynaptic cell ...
