Definition of reuptake
: the reabsorption by a neuron of a neurotransmitter following the transmission of a nerve impulse across a synapse.
What is reuptake and how does it work?
Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse.
What is reuptake psychology?
Reuptake refers to the process in the brain of neurons to retrieve chemicals that were not received by the next neuron. Neurons are cells in the brain that have miniscule spaces between them. They communicate with each other by sending chemicals across the space to the next neuron.
What does reuptake of a drug mean?
Reuptake: The reabsorption of a secreted substance by the cell that originally produced and secreted it. The process of reuptake, for example, affects serotonin.
What happens in reuptake?
Reuptake is what happens after a signal is transmitted: The neurotransmitter, its “work” completed, is reabsorbed back into the cell that previously released it.
What does reuptake mean in SSRI?
After carrying a message, serotonin is usually reabsorbed by the nerve cells (known as “reuptake”). SSRIs work by blocking (“inhibiting”) reuptake, meaning more serotonin is available to pass further messages between nearby nerve cells.
What happens after reuptake?
4. Reuptake: the whole neurotransmitter molecule is taken back into the axon terminal that released it. This is a common way the action of norepinephrine, dopamine and serotonin is stoppedthese neurotransmitters are removed from the synaptic cleft so they cannot bind to receptors.
What is the difference between uptake and reuptake?
As nouns the difference between uptake and reuptake
is that uptake is understanding, comprehension while reuptake is (rare) a second or subsequent uptake.
What does reuptake mean in the process of neurotransmitters?
n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them. Reuptake is performed by transporter proteins in the presynaptic membrane.
What is reuptake quizlet?
Reuptake. the process in which excess neurotransmitters are reabsorbed by the sending neuron. Acetylcholine. a neurotransmitter that enables learning and memory and also triggers muscle contraction.
What causes reuptake of serotonin?
When brain cells send signals to one another, they release neurotransmitters, including serotonin. Before they can send the next signal, the cells must reabsorb and recycle the neurotransmitters they have released. This process is called reuptake.
What drugs affect reuptake?
Inhibition of Serotonin Reuptake: Drugs that inhibit serotonin reuptake include chlorpheniramine; cyclobenzaprine; dextromethorphan (e.g., Robitussin DM); meperidine; methadone; pentazocine; sibutramine; SSRIs (e.g., citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine); St.
What drugs block reuptake?
The reuptake inhibitors used to treat mood disorders are classified by the types of neurotransmitter pathway they block.
Types of Reuptake Inhibitors
Celexa (citalopram)Lexapro (escitalopram)Luvox (fluvoxamine)Paxil (paroxetine)Prozac (fluoxetine)Zoloft (sertraline)
What happens to serotonin after reuptake?
Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons. This makes more serotonin available to improve transmission of messages between neurons.
What is reuptake quizlet?
Reuptake. the process in which excess neurotransmitters are reabsorbed by the sending neuron. Acetylcholine. a neurotransmitter that enables learning and memory and also triggers muscle contraction.

What is the process of reuptake in neurotransmitters?
n. the process by which neurotransmitter molecules that have been released at a synapse are reabsorbed by the presynaptic neuron that released them. Reuptake is performed by transporter proteins in the presynaptic membrane.
