nerve impulse transmission

Front

What opens during repolarization of a neuron?

Back

K+ gates and Na+/K+ pump open during repolarization.

Front

What does action potential refer to?

Back

Action potential refers to a change of charge between the inside and outside of the neuron.

Front

What does not affect the transmission speed of a neuron cell?

Back

The strength of the stimulus does not affect the transmission speed of a neuron cell.

Front

What is true about neurotransmitters?

Back

Neurotransmitters transmit nerve impulses from one neurone to another neurone.

Front

What happens during the second period of the action potential graph?

Back

Na+ gates open during the second period of the action potential graph.

Front

What is the role of K+ gates during nerve impulse transmission?

Back

K+ gates help in repolarizing the neuron after an action potential.

Front

What is the function of the Na+/K+ pump?

Back

The Na+/K+ pump helps maintain the resting membrane potential by pumping Na+ out and K+ into the neuron.

Front

What is the resting membrane potential of a neuron?

Back

The resting membrane potential of a neuron is typically around -70 mV.

Front

How does myelination affect nerve impulse transmission?

Back

Myelination increases the speed of nerve impulse transmission by allowing saltatory conduction.

Front

What is saltatory conduction?

Back

Saltatory conduction is the process where action potentials jump from one node of Ranvier to another, speeding up transmission.
