How Neurotransmitter molecules are removed from a synapse by?
Neurotransmitter molecules are removed from a synapse through a process called reuptake or enzymatic degradation. In reuptake, the neurotransmitter is taken back up into the presynaptic neuron. In enzymatic degradation, special enzymes break down the neurotransmitter molecules into inactive byproducts.
What is the name of the small space between two neurons where neurotransmitter molecules are released?
The small space between two neurons where neurotransmitter molecules are released is called the synapse.
Reuptake refers to the?
reabsorption of excess neurotransmitter molecules by a sending neuron
The reabsorption of excess neurotransmitter molecules by a sending neuron is called?
The reabsorption of excess neurotransmitter molecules by a sending neuron is called "reuptake." This process helps regulate neurotransmitter levels in the synaptic cleft, ensuring that signaling between neurons is appropriately balanced. Reuptake is a crucial mechanism for maintaining neurotransmitter homeostasis and can influence mood, behavior, and various neurological functions.
How do signal molecules change how a cell will function?
Signal molecules act as a neurotransmitter or a hormone, which both effect how a cell functions.
What are the molecules that are similar enough to a neurotransmitter to bind to its receptor sites on a dendrite and mimic that neurotransmitter's effects called?
Molecules that are similar enough to a neurotransmitter to bind to its receptor sites on a dendrite and mimic its effects are called agonists. These can be naturally occurring substances or synthetic drugs that activate receptor sites, leading to similar physiological responses as the original neurotransmitter. Examples include morphine, which mimics endorphins, and nicotine, which mimics acetylcholine.
What is the re absorption of excess neurotransmitter molecules?
Reabsorption of excess neurotransmitter molecules refers to the process where neurotransmitters are taken back up from the synaptic cleft into the presynaptic neuron by transporters known as reuptake pumps. This process helps regulate neurotransmitter levels, preventing overstimulation of the postsynaptic neuron. Dysfunction in this reabsorption process can lead to neurological disorders such as depression and anxiety.
The process in which enzymes within neurons convert precusors into neurotransmitter molecules is called?
The process is called neurotransmitter synthesis. It involves the conversion of precursor molecules into neurotransmitters by specific enzymes within neurons. This process is crucial for the production of neurotransmitters that are essential for communication between neurons in the brain.
These lipid molecules may function as retrograde neurotransmitters and allow the postsynaptic neuron to decrease release of neurotransmitter from the presynaptic neuron?
endocannabinoids
As the action potential frequency in a presynaptic neuron increases the number of vesicles undergoing exocytosis and the number of released neurotransmitter molecules?
Increases, leading to more neurotransmitter release at the synapse. This can result in a stronger postsynaptic response in the receiving neuron.
What specific neurotransmitter is released from the axon terminus?
You do not have single neurotransmitter, which is released from axon terminals. There are many. Some facilitate the conduction of the impulse and others inhibit the same. You have acetylcholine, norepinephrine, dopamine and many others acting as neurotransmitter.
What is the medical term meaning neurotransmitter?
neurotransmitter
