Neurotransmissores Flashcards
What is a neurotransmitter?
A neurotransmitter is a chemical messenger that transmits signals across a synapse from one neuron to another.
True or False: Neurotransmitters can only be excitatory.
False: Neurotransmitters can be either excitatory or inhibitory.
Fill in the blank: The neurotransmitter _______ is primarily involved in mood regulation.
serotonin
Which neurotransmitter is known as the ‘feel-good’ neurotransmitter?
Dopamine
What role does acetylcholine play in the body?
Acetylcholine is involved in muscle contraction and memory.
Multiple Choice: Which of the following neurotransmitters is primarily associated with the fight or flight response? A) Serotonin B) Norepinephrine C) GABA D) Glutamate
B) Norepinephrine
What is the function of GABA?
GABA is an inhibitory neurotransmitter that reduces neuronal excitability.
True or False: Endorphins are neurotransmitters that help alleviate pain.
True
Fill in the blank: The neurotransmitter _______ is primarily involved in learning and memory.
glutamate
Which neurotransmitter is linked to attention and focus?
Dopamine
Multiple Choice: Which neurotransmitter is primarily inhibitory? A) Glutamate B) GABA C) Acetylcholine D) Norepinephrine
B) GABA
What neurotransmitter is released during stress?
Norepinephrine
True or False: Serotonin is only found in the brain.
False: Serotonin is also found in the gastrointestinal tract.
Fill in the blank: The neurotransmitter _______ is often associated with addiction.
dopamine
What is the primary function of norepinephrine?
Norepinephrine is involved in arousal and alertness.
Multiple Choice: Which neurotransmitter is primarily associated with anxiety disorders? A) Serotonin B) GABA C) Dopamine D) Both A and B
D) Both A and B
What effect does glutamate have on neurons?
Glutamate generally has an excitatory effect on neurons.
True or False: Neurotransmitters can only act on specific receptors.
True
Fill in the blank: The neurotransmitter _______ is critical for motor control.
dopamine
Which neurotransmitter is often referred to as the ‘stress hormone’?
Cortisol (note: while cortisol is a hormone, it is often discussed in the context of neurotransmitter activity during stress responses.)
What is the role of neurotransmitters in mental health?
Neurotransmitters play a crucial role in regulating mood, behavior, and cognitive functions.
Multiple Choice: Which neurotransmitter is most commonly associated with depression? A) Norepinephrine B) Serotonin C) Dopamine D) All of the above
D) All of the above
What is the relationship between neurotransmitters and receptors?
Neurotransmitters bind to receptors on neurons to transmit signals.
True or False: Neurotransmitters can be recycled after their action.
True
