Which drug acts as a false neurotransmitter?

α-Methyldopa is one of a group of antihypertensive drugs called false neurotransmitters that replace norepinephrine in the synaptic vesicles located in postganglionic nerve endings of the SNS.

What are false transmitters?

: a biological amine that can be stored in presynaptic vesicles but that has little or no effect on postsynaptic receptors when released into the synaptic cleft. — called also false transmitter.

What is a true neurotransmitter?

As briefly described in the preceding chapter, neurotransmitters are chemical signals released from presynaptic nerve terminals into the synaptic cleft.

What is an example of neurotransmission?

Examples of these types of neurotransmitter are GABA and endorphins. Neuromodulators do not directly activate the receptors of neurons but work together with neurotransmitters to enhance the excitatory or inhibitory responses of the receptors. Examples of these types of neurotransmitter are serotonin and dopamine.

Which is an example of a false neurotransmitter?

Examples include 5-MeO-αMT (mimicking serotonin) and α-methyldopa . These chemicals can be accumulated by a neuron or secretory cell, are then packaged in secretory / synaptic vesicles, and then released with other neurotransmitters when an action potential provides the necessary stimulus for release.

What is the medical term for false transmitter?

: a biological amine that can be stored in presynaptic vesicles but that has little or no effect on postsynaptic receptors when released into the synaptic cleft. — called also false transmitter.

Which is a false transmitter of octopamine and tyramine?

Tyramine can also be converted into octopamine by the dopamine-beta-hydroxylase (DBH) which itself acts as a false transmitter by displacing noradrenaline from its vesicle but not activating the postsynaptic alpha adrenoreceptor.

Are there substitute neurotransmitters in the conscious brain?

There is growing evidence that a large number of well known exogenous chemicals work as substitute neurotransmitters, though the distinction between the classical model and the substitute neurotransmitter model only becomes apparent with neurotransmitters central to the signaling in the conscious brain, like dopamine and serotonin (as mentioned
