20 Questions
What is the role of dendrites in the process of neurotransmission?
Dendrites pick up the message from the previous cell
In the process of neurotransmission, what occurs at the presynaptic terminal?
The action potential is converted into a chemical signal
What is the function of voltage-gated calcium channels in neurotransmission?
Regulate the release of neurotransmitters at the presynaptic terminal
What characterizes retrograde neurotransmission?
The postsynaptic neuron releases neurotransmitters to communicate with the presynaptic neuron
What type of receptors are most common for psychotropic drugs?
G-linked Receptors
Which transporter is responsible for serotonin uptake and has an affinity for MDMA?
SERT
What do monoamine transporters depend on to bind to receptors and transport neurotransmitters?
Sodium
Which type of neurons sends information?
Axon
What is the main theory regarding the cause of psychiatric disorders according to the text?
Dysfunction in neurotransmitter transmission
Which neurotransmitter is responsible for maximizing gene expression and actions in cells?
Dopamine
What is the role of dendrites in the process of neurotransmission according to the text?
Pick up the message from the previous cell
What characterizes Volume Neurotransmission as mentioned in the text?
Involves diffusion of chemical messengers without synapses
What defines Retrograde Neurotransmission based on the text?
Presynaptic neurons responding to chemical signals from postsynaptic neurons
What is Excitation-Secretion Coupling as described in the text?
A process where electrical impulses trigger a chemical cascade altering neuron functioning
What is the role of Vesicular Monoamine Transporter 2 (VMAT2) in neurotransmission?
It keeps neurotransmitters safe from enzymes until their release.
Which neurotransmitter is NOT mentioned in the text as a key neurotransmitter?
Histamine
What is the function of G-linked Receptors in neurotransmission?
They mediate the action of psychotropic drugs.
How do Monoamine transporters affect neurotransmission?
By facilitating the binding and transport of neurotransmitters.
What is the primary structural difference between axodendritic and axoaxonic synapses?
The location on the neuron where they form.
What happens when an agonist binds to a G-linked receptor in neurotransmission?
It maximizes gene expression and cell actions.
Test your knowledge on the pathway of an electrical impulse in a neuron, from dendrites to axon terminals. Learn about the conversion of an action potential into a chemical signal at the presynaptic terminal and the transmission to postsynaptic terminals.
