are endogenous chemicals which relay, amplify, and modulate signals between a neuron and another cell.[1] Neurotransmitters are packaged into synaptic vesicles that cluster beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation.

What is the medical term meaning neurotransmitter?
neurotransmitter
Reuptake refers to the?
reabsorption of excess neurotransmitter molecules by a sending neuron
What is permissive action as in the nervous system?
In the nervous system, permissive action refers to one neurotransmitter enhancing the effect of another neurotransmitter. This occurs when one neurotransmitter prepares receptors to be more responsive to another neurotransmitter, allowing for a more amplified response.
Can long term usage of amphetamines for attention deficit disorder cause neurotransmitter imbalances and depression?
answer is yes
Adrenaline rush refers to the action of which neuro transmitter?
As a hormone and neurotransmitter, epinephrine acts on nearly all body tissues.
What term refers to a Tempo?
Andante is a term that refers to a tempo.
Which term refers to a Tempo?
Andante is a term that refers to a tempo.
What is epinephine?
You probably mean "epinephrine". This is the preferred term to use when referring to the neurotransmitter/hormone that used to be known as "adrenaline".
What neurotransmitter does long-term potentiation depend on?
Long-term potentiation (LTP) primarily depends on the neurotransmitter glutamate, specifically its activation of NMDA receptors to initiate the signaling cascade that underlies the strengthening of synaptic connections. Dopamine and other neurotransmitters also play modulatory roles in LTP.
What is the critical point called node of ranvier neurotransmitter threshold?
The term "node of Ranvier" refers to the small gaps in the myelin sheath of a neuron where action potentials are regenerated. These nodes play a crucial role in saltatory conduction, allowing electrical impulses to jump from one node to the next, thereby increasing the speed of nerve signal transmission. The "neurotransmitter threshold" is not directly related to the nodes but refers to the level of stimulation required for a neuron to generate an action potential. Together, these concepts illustrate the intricacies of neuronal communication and signal propagation.
The term alkali or alkaline refers to properties of what?
The term refers to properties of a base.
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.
