2024 Neurons 2 synaptic cleft

Front

What is the main electrolyte involved in creating the action potential?

Back

Sodium (Na) is the main electrolyte involved in creating the action potential.

Front

What is the benefit of allowing serotonin to remain in the synaptic cleft longer?

Back

Allowing serotonin to remain in the synaptic cleft longer enables it to be used repeatedly, enhancing its effects.

Front

What role does calcium play during a synapse?

Back

Calcium stimulates vesicles to fuse with the plasma membrane, facilitating neurotransmitter release.

Front

What creates chemical energy during a synapse?

Back

Neurotransmitters create chemical energy during a synapse.

Front

During re-uptake, where are neurotransmitters removed from the synaptic cleft brought back into?

Back

Neurotransmitters are brought back into the synaptic end bulb during re-uptake.

Front

What is the function of neurotransmitters in the nervous system?

Back

Neurotransmitters transmit signals across synapses between neurons.

Front

What is the synaptic cleft?

Back

The synaptic cleft is the small gap between the presynaptic and postsynaptic neurons where neurotransmitters are released.

Front

How do action potentials propagate along a neuron?

Back

Action potentials propagate along a neuron through the sequential opening and closing of voltage-gated ion channels.

Front

What is the difference between excitatory and inhibitory neurotransmitters?

Back

Excitatory neurotransmitters increase the likelihood of an action potential, while inhibitory neurotransmitters decrease it.

Front

What is the process of synaptic transmission?

Back

Synaptic transmission is the process by which neurotransmitters are released from the presynaptic neuron, cross the synaptic cleft, and bind to receptors on the postsynaptic neuron.
