Signaling Between Neurons

Front

What triggers the release of neurotransmitters from the synaptic vesicles into the synaptic cleft?

Back

Calcium ions

Front

Role of calcium ions in synaptic transmission?

Back

They facilitate the fusion of synaptic vesicles with the presynaptic membrane.

Front

What is the primary function of neurotransmitter receptors on the postsynaptic membrane?

Back

To bind neurotransmitters and initiate a cellular response

Front

Effect of inhibitory neurotransmitters on the postsynaptic membrane potential?

Back

Hyperpolarization

Front

Common inhibitory neurotransmitter in the central nervous system?

Back

GABA

Front

What is the role of synaptic vesicles in neurotransmitter release?

Back

They store neurotransmitters until they are released.

Front

Which mechanisms are involved in the termination of neurotransmitter action at the synapse?

Back

Reuptake into the presynaptic neuron, Diffusion away from the synapse, Enzymatic degradation

Front

What is the primary ion involved in generating an excitatory postsynaptic potential (EPSP)?

Back

Sodium ions

Front

Which of the following best describes the process of receptor binding in synaptic transmission?

Back

Neurotransmitters bind to receptors, causing ion channels to open or close.

Front

What is the effect of calcium ion influx on synaptic vesicles?

Back

It causes them to fuse with the presynaptic membrane.
