Final answer:
Neurotransmitters are released in a specific order depending on the level of stimulation and the specific neurotransmitter system. Typically, neurotransmitters are released at lower levels of stimulation and other neurotransmitters are released athigher levels of stimulation.
Step-by-step explanation:
In the nervous system, there are several systems of neurotransmitters that are released at various synapses. The order in which neurotransmitters are released depends on the specific system and the level of stimulation. Generally, neurotransmitters are released at lower levels of stimulation, while neurotransmitters released at higher levels of stimulation.
For example, in the dopaminergic system, dopamine is released at lower levels of stimulation. As the level of stimulation increases, other neurotransmitters like norepinephrine and epinephrine may be released.
It's important to note that the specific order of neurotransmitter release can vary depending on the context and the specific neurotransmitter systems involved.
