neutrotransmitters
Epinephrine, norepinephrine, dopamine, serotonin.
Chemical neurotransmitters. Examples of 'classical neurotransmitters' include acetylcholine, dopamine, serotonin, noradrenaline and GABA (gamma-aminobutyric acid).
Dopamine can be supplied as a medication that acts on the sympathetic nervous system, producing effects such as increased heart rate and blood pressure. However, because dopamine cannot cross the blood-brain barrier, dopamine given as a drug does not directly affect the central nervous system. To increase the amount of dopamine in the brains of patients with diseases such as Parkinson's disease and dopa-responsive dystonia, L-DOPA (levodopa), which is the precursor of dopamine, can be given because it can cross the blood-brain barrier.

A neurotransmitter is a chemical or peptide in synapses, usually between neurons, a neuron and muscle or a neuron and other organ. The neurotransmitter transmits information to and from and within the brain. When a neurotransmitter is released from the presynaptic cell in response to depolarization of the cell by an action potential, it diffuses across the synaptic cleft and binds a receptor or ligand-gated ion channel on the postsynaptic cell. Binding on the postsynaptic cell alters the resting potential of the postsynaptic cell in either an inhibitory or excitatory manner, making the cell less susceptible or more susceptible (respectively) to an action potential. Examples include, but are not limited to, acetylcholine, GABA, noradrenaline, serotonin and dopamine.
They are examples of organelles
Epinephrine, norepinephrine, dopamine, serotonin.
Examples of neurtransmitter are, acetylcholine, norepinephrine, dopamine and serotin,
Examples of neurotransmitters are: acetylcholine, dopamine, norepinephrine, and epinephrine. They also act as hormones but basically they are neurotransmitters that helps send nerve impulses to the brain through axons so that a certain action can be done by a muscle or gland.
Neurotransmitters. Some examples: glutamate, GABA (gamma-aminobutyric acid), epinephrine, norephinephrine, acetylcholine, dopamine, serotonin
Serotonin is a neurotransmitter that is mainly found in the Gastrointestinal Tract and the Central Nervous System. Serotonin is mostly used to regulate intestinal movement within the intestines but the rest with in the body is used to regulate various functions through the Central Nervous System. Examples of Serotonin regulated functions are mood, appetite, sleep, muscle contractions, and some cognitive functions like memory or learning. Noradrenaline, or Norepinephrine, is another neurotransmitter that has a dual role as a hormone. Norepinephrine is involved in the human body's Fight-or-Flight response. Norepinephrine as well as Epinephrine, increases heart rate, triggers the release of glucose from storage in the body, and increases blood flow to muscles.

Seratonin and dopamine
Small chemicals called 'neurotransmitters' that are released into the synapse will diffuse across the synaptic cleft and bind to postsynaptic receptors (which may be on a cell body, or a dendrite). Examples of neurotransmitters are: adrenaline/epinephrine, acetylcholine, glutamate, serotonin, GABA, glycine and dopamine.
The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!

Inotropic agents example are positive inotrops- digoxin, adrenaline, nor adrenaline,dopamine,dobutamine, amrinone, etc.
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
