Crossing the Synaps Flashcards
(15 cards)
What are neurotransmitters?
Chemicals that transmit signals across a synapse from one neuron to another.
True or False: Neurotransmitters can only be excitatory.
False
What is the role of the synaptic cleft?
It is the space between neurons where neurotransmitters are released.
Fill in the blank: The two main types of neurotransmitters are ________ and ________.
excitatory; inhibitory
What neurotransmitter is primarily associated with mood regulation?
Serotonin
Which neurotransmitter is known for its role in reward and pleasure?
Dopamine
Multiple Choice: Which of the following is an inhibitory neurotransmitter? A) Glutamate B) GABA C) Acetylcholine
B) GABA
What is the function of acetylcholine?
It plays a role in muscle contraction and memory.
True or False: Neurotransmitters are stored in vesicles at the axon terminal.
True
What happens to neurotransmitters after they have transmitted their signal?
They are either broken down by enzymes or reabsorbed by the presynaptic neuron.
Fill in the blank: The process of neurotransmitter release is triggered by ________ influx into the axon terminal.
calcium
Multiple Choice: Which neurotransmitter is involved in the fight or flight response? A) Serotonin B) Norepinephrine C) GABA
B) Norepinephrine
What is the primary function of glutamate?
It acts as the main excitatory neurotransmitter in the brain.
True or False: Neurotransmitters can affect only the neuron that released them.
False
What is reuptake in the context of neurotransmitters?
The process by which neurotransmitters are reabsorbed by the presynaptic neuron.
