is a substance that is produced by a neuron that is other than a neurotransmitter and is used to transmit information to other neurons to regulate their activities. examples are dopamine, s.erotonin or histamine

What are neurotransmitters that affect a neuron's response to other neurotransmitters called?
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Because enkephalins and endorphins often alter a cell's response to a neurotransmitter they are called neuromodulators?
TRUE.
What are considered not true neurotransmitters?
Not all chemical messengers in the brain are classified as true neurotransmitters. Some examples include neuropeptides, endocannabinoids, and gasotransmitters like nitric oxide. These substances modulate neural activity and play important roles in brain function, but they differ from classical neurotransmitters in their structure or mode of action.
What effect do neurotransmitters from one neuron have on the next neuron?
The two major effects are excitatory and inhibitory. For example ACh leads to the post-synaptic cell's depolarization while GABA or glycine will hyperpolarize the post-synaptic cell. But this is all a simplification. Some synapses have an effect of neuromodulators sometimes released as a co-transmitter (e.g. NPY and epinephrine from sympathetic ganglionic neurons). In some situations the cotransmitter can have a mixture of effects.
What do neurotransmitters open?
Neurotransmitters act on synapses.
What neurotransmitters are amino acids?
define amino acids in neurotransmitters
Which structure in the body releases neurotransmitters?
Neurons release neurotransmitters.
What is the relationship between drugs and the transmission of neurotransmitters?
The relationship between drugs an the transmission of neurotransmitters is that the drugs can interfere with the work of the neurotransmitters.
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Certain mental problems are thought to be caused by not having enough neurotransmitters. Why would a lack of neurotransmitters cause problems?
Neurotransmitters send signals from neuron to neuron
What state of matter is the mind?
The mind is not any state of matter.The mind is an epiphenomenon of the electrobiochemistry happening in the unbelievably complicated network of neurons, myelin, neurotransmitters, neuromodulators, neuroregulators, hormones, etc. that make up the about three pounds of largely fatty tissue enclosed in our bony skull that we refer to as a brain.
Are there neurotransmitters in our intestines and organs?
Yes, neurotransmitters are found wherever nerves are found.
