What are examples of natural amines?
Examples of natural amines include histamine, serotonin, and dopamine, which are important neurotransmitters in the body. Amines are also found in various plant and animal proteins such as meat, fish, eggs, and nuts. Histamine, for example, is present in fermented foods like cheese and wine.
What drug inhibits the reuptake of dopamine serotonin and norepinephrine into presynaptic axon terminals?
The drug that inhibits the reuptake of dopamine, serotonin, and norepinephrine into presynaptic axon terminals is a type of antidepressant medication known as a tricyclic antidepressant (TCA). Examples of TCAs include amitriptyline, imipramine, and nortriptyline. By blocking the reuptake of these neurotransmitters, TCAs increase their levels in the brain, which can help alleviate symptoms of depression.
What are neural regulators?
Neural regulators are chemicals in the brain that help regulate nerve cell function. They play a crucial role in controlling various physiological processes such as mood, appetite, and sleep. Examples include neurotransmitters like serotonin, dopamine, and norepinephrine.
Are first messengers hydrophobic?
First messengers are typically hydrophilic molecules or ions that cannot pass through the cell membrane. Common examples include hormones (such as epinephrine and insulin) and neurotransmitters (such as serotonin and dopamine). These molecules bind to cell surface receptors to initiate signaling cascades within the cell.
What are the chemicals that are released at an axon terminal and can either excite or inhibit other neurons called?
Neurotransmitters are the chemicals released at an axon terminal that can either excite or inhibit other neurons. They help transmit signals across the synapses between neurons in the nervous system. Examples of neurotransmitters include dopamine, serotonin, and GABA.

What does neurotansmitter mean?
Examples of neurtransmitter are, acetylcholine, norepinephrine, dopamine and serotin,
What are neural regulators?

What is the chemical messenger of the nervous system?
There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones. 1) Neurotransmitters are released by transmitting neurons. They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. Some neurotransmitters are: Serotonin, dopamine, acetylcholine, gamma-aminobutyric acid (GABA), norepinephrine (also a hormone) and glutamate. 2) Endorphins help in pain reduction, pleasure and even memory. 2) Hormones are affects the functioning of organs and are released by glands. Some hormones include: Melatonin, oxytocin, adrenal hormones (cortisol, epinephrine, norepinephrine) and sex hormones (androgens, estrogens and progesterone).
What are the examples of neurtransmitters?
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.
What is the name of the chemical neurons send to communicate with other neurons?
Neurotransmitters. Some examples: glutamate, GABA (gamma-aminobutyric acid), epinephrine, norephinephrine, acetylcholine, dopamine, serotonin
What is serotonin and noradrenaline?
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.
What are two examples of neurotransmitters?
Seratonin and dopamine
What goes from the synapse to the cell body?
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.
What is neurotransmitter is best described as?
A neurotransmitter is a chemical messenger that transmits signals across synapses in the brain and nervous system. These molecules play a crucial role in regulating various physiological processes, including mood, behavior, and cognition. Examples of neurotransmitters include dopamine, serotonin, and acetylcholine.
Are first messengers hydrophobic?
First messengers are typically hydrophilic molecules or ions that cannot pass through the cell membrane. Common examples include hormones (such as epinephrine and insulin) and neurotransmitters (such as serotonin and dopamine).
