Foundation 2 Neurotransmitters Flashcards
What is acetylcholine?
A neurotransmitter used by somatic neurons that contract the large muscles.
What roles does acetylcholine play?
It plays a role in memory and dreaming.
What disease is related to low levels of acetylcholine?
Alzheimer’s disease is related to low levels of acetylcholine.
What is dopamine?
A neurotransmitter substance used by neurons in the brain that control large muscle movements.
What happens when dopamine is depleted?
Depletion of dopamine leads to uncontrolled muscle tremors (Parkinson’s disease).
What roles does dopamine play in the brain?
Dopamine plays a central role in pleasure and reward system in the brain and is involved in schizophrenia and attention deficit hyperactivity disorder (ADHD).
What is serotonin?
A neurotransmitter that regulates sleep cycles and dreaming, appetite, anxiety, and the inhibition of violence.
What happens when serotonin is depleted?
Serotonin depletion leads to depression.
What is norepinephrine?
A neurotransmitter that plays a role in attention to important events, such as the presence of danger in the environment.
What mental health conditions is norepinephrine involved in?
It is involved in anxiety and depression.
What is glutamate?
A neurotransmitter that plays a key role in the regulation of cognition and emotion.
What happens when glutamate is depleted?
Glutamate depletion leads to schizophrenia.
What are neuropeptides?
A large group of neurotransmitters (neuromodulators).
What do neuropeptides influence?
They broadly influence the action of the other neurotransmitters.
