Synapse/Neurotransmitter Flashcard

Front

What is a synapse?

Back

A synapse is a structure that allows one neuron to communicate with another neuron.

Front

What is the role of neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another.

Front

Where are neurotransmitters released from?

Back

Neurotransmitters are released from the presynaptic neuron.

Front

What is the synaptic cleft?

Back

The synaptic cleft is the gap between the presynaptic neuron and the postsynaptic neuron.

Front

What is the function of the presynaptic neuron?

Back

The presynaptic neuron is responsible for releasing neurotransmitters into the synaptic cleft.

Front

What is the function of the postsynaptic neuron?

Back

The postsynaptic neuron receives neurotransmitters and responds to the signal.

Front

What is acetylcholine?

Back

Acetylcholine is a neurotransmitter that is involved in muscle movements and memory.

Front

What are endorphins?

Back

Endorphins are neurotransmitters that act as natural painkillers and are involved in pleasure and reward.

Front

What is serotonin?

Back

Serotonin is a neurotransmitter that contributes to feelings of well-being and happiness.

Front

What is GABA?

Back

GABA (gamma-aminobutyric acid) is a neurotransmitter that inhibits nerve transmission in the brain, calming nervous activity.
