What are the criteria for a substance in a neurotransmitter at a synapse?
Criteria required identifying a substance as a neurotransmitter 1- ) Synthesis of the substance: • It is synthesized in the neuron • Some substances are synthesized from the Tryptophan • Rate limiting step in its synthesis • Enzymes required in the synthesis of that substance are themselves synthesized in the cell body of neuron ,then distributed throughout the neuron • Mainly found in the cell body and nerve terminal • These enzymes are stored in the presynaptic terminal of neuron, inside the synaptic vesicles. 2- ) Storage of that substance: • The neutransmitter is stored inside the synaptic vesicle of nerve terminal 3- ) Release of the neurotransmitter: • It is released from the nerve terminal usually through Ca++ dependent process following the stimulation of the nerve fiber by action potential. • Fusion of the synaptic vesicle with the nerve membrane releasing neurotransmitter outside the nerve fiber into the synaptic cleft. 4- ) Exogenous analogue (drug) of the neurotransmitter: • If drug analogue of the neurotransmitter is injected exogenously, it should mimic the same mechanism of action as done by the endogenously released neurotransmitter.
What is ARX model?

What is exogenous activity?
Exogenous behavior is the behavior that is derived externally and outside the body. Exogenous behavior can also be in reference to outside sources that effect us, such as temperature and sunlight.
When b cells secrete antibodies does it fight against endogenous or exogenous pathogens?
exogenous pathogens.
What do exogenous sources of infection include?
Exogenous infection is a bacterial infection that develops from the outside of the body. Exogenous bacteria are foodborne and waterborne which can be consumed directly or through secondary host.
What is the definition of exogenous?
Exogenous is the use of something from outside the organism - such as insulin. A link with a longer definition is below.
What is exogenous virus?
I believe, exogenous virus exist as: "replication competent viruses that are transmitted horizontally in mice, while endogenous viruses exist as germline sequences that are usually not replication competent by may recombine with exogenous viruses during the course of infection." This would refer to exogenous retroviruses.
What is an exogenous processes?
An exogenous process is a factor or variable that originates from outside the system being studied. In other words, it is a driver or input that influences the system but is not influenced by the system itself. Exogenous processes are important to consider in various fields such as economics, biology, and social sciences to understand the impact of external factors on the system under investigation.
Define and differentiate between endogenous and exogenous variables?
The endogenous variables value is established by the conditions of the other variables in the structure. The exogenous variables value in independent of the conditions of the other variables in the structure. The difference between the endogenous and exogenous variables is the endogenous depends solely on the structure and the exogenous depend on outside elements.
Is endotoxin an exogenous pyrogen?
true
