Session 12 - Neurotransmitters Flashcards
Which NT may help decrease pain?
Adrenaline reduces the body’s ability to feel pain and increases momentary strength by triggering blood vessels to contract and re-direct blood toward major muscle groups, including the heart and lungs (fight or flight).
What does serotonin manage and control?
Digestion Appetite Social behaviour Memory Sleep
T/F neurons have direct contact with each other which is how they transfer information.
False - Neurons do not talk directly but use special chemicals called neurotransmitters. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons).
Which NT is inhibitory in its action?
Glycine
Which NT is responsible for reward pathways and may help with addictions?
Dopamine - is the neurotransmitter related to feelings of pleasure. Its deficiency is associated with several mental health disorders (for example, eating disorders, non-suicidal self-injury, compulsive sex behaviours, internet gaming, gambling).
T/F Alanine is the amino acid precursor to Noradrenalin.
F – Tyrosine is.
A client is feeling mildly depressed and anxious. Which NT deficiency may be involved?
GABA is an inhibitory neurotransmitter of the brain that functions to inhibit excitatory signals and activity of the nervous system.
What does GABA help to do?
- Reduce Anxiety
* Control motor function
Which nutrients are important for Serotonin production?
Tryptophan is converted to 5HTP, which is then converted to serotonin, this process requires:
Vitamin C, B6 and Zinc and cofactors
What are Neurotransmitters?
Molecules that communicate info between neurons and target cells at chemical synapses.
Our body’s chemical messengers
T/F the amino acid glutamate is required for GABA synthesis
This statement is true. GABA is synthesised from glutamate by the enzyme L-glutamic acid decarboxylase and uses pyridoxal phosphate (B6) as a cofactor.
T/F availability of choline and acetyl CoA is the limiting step in the formation of acetylcholine
True - Acetylcholine is synthesised from choline and acetyl coenzyme A (acetyl CoA) in nerve terminals.
T/F GABA is the NT associated with IBS diarrhoea
F- Serotonin is the neurotransmitter associated with IBS-diarrhoea.
Name the groups of neurotransmitters
Amino Acid neurotransmitters
Monoamines
Peptides & Other
Gives examples of amino NT’s (nervous system function)
Glutamate (+most common) excites
Gaba (inhibitory - brain).
Glycine (inhibitory - spinal cord).
