The action potential causes neurotransmitters to be released into the?
synapse
When the action potential arrives synaptic vesicles containing neurotransmitters are released by what?
The voltage-gated Ca2+ channels are opened when an action potential releases neurotransmitters from a neuron. A neuron transmits nerve impulses.
What part of a neuron contains neurotransmitters?
Neurotransmitters are used to send messages from cell to cell, usually neuron to neuron. Neurotransmitters are released from the pre-synapse, which is at the axon terminus. These neurotransmitters are picked up by the post-synapse on the receiving cell. These post-synapses are located on structures called dendrites or on the cell body.
What does Synaptic Vesicles contain?
A small membrane-bound structure in the axon terminals of nerve cells that contains neurotransmitters and releases them by exocytosis when an action potential reaches the terminal.
Sticky ends are produced as a result of the action of?
DNA ligase

Where are neurotransmitters produced?
The nervous system is traditionally considered the main producer of neurotransmitters. They are produced in the cyton, or soma; the body of the nerve cell that contains the nucleus. They are then transported to the synaptic vessicles where they wait to be released by an action potential by stimulation.
The action potential causes neurotransmitters to be released into the?
synapse
Where do neurotransmitters that bind the postsynaptic membrane generate?
action potential
What hormone action is used by neurotransmitters and olfactory receptors?
cAMP
Do neurotransmitters help to create new action potential?
Yes.
What is difference between site of action and onset of action?
site of action is the location (site) where the drug do there action ........ while onset of action is the starting of effects produced due to drug............... both are clearly different..........
Which mechanisms of hormone action is used by neurotransmitters and olfactory receptors?
cAMP
How do action potentials move from one neuron to another?
The action potential stimulates the axon terminal to release its neurotransmitters. The neurotransmitters attach themselves to the dendrote of the next neuron, so that it will open its NA+ channels.
WHAT are neurotransmitters are inhibitory?
neurotransmitters are called Inhibitory if the activation of the receptors causes hyper-polarisation and depresses action potential generation (slows down processes)
Action potentials trigger the release of chemicals in the terminal buttons called?
neurotransmitters
Which of the following mechanisms of hormone action is used by neurotransmitters and olfactory receptors?
cAMP
