Which of the Following Will Occur When a Neuron Depolarizes

The membrane potential changes from the resting potential to a more negative membrane potential. Sodium flows into the cell.

Q What Happens In The Depolarization Of A Nerve Studentrdh Blog

Which of the following occurs when a stimulus depolarizes a neurons membrane to a membrane potential below the voltage threshold.

. All of the above occur. The inside of the cell becomes less negative in charge relative to the outside of the cell. Both a and c occur.

Some of the events that occur during this reflex are listed below. During the depolarization phase the gated sodium ion channels on the neurons membrane suddenly open and allow sodium ions Na present outside the membrane to rush into the cell. A Voltage sensitive gates that permit a rapid out flow of Na open.

During the depolarization phase the gated sodium ion channels on the neurons membrane suddenly open and allow sodium ions Na present outside the membrane to rush into the cell. Voltage-gated potassium channels close. As the sodium ions quickly enter the cell the internal charge of the nerve changes from -70 mV to -55 mV.

Voltage-gated sodium channels close. The action potential stops spreading to the next dendrite. Which of the following occurs when a stimulus depolarizes a neuron membrane.

-Motor control over voluntary movement. C The membrane potential changes from the resting potential to a voltage closer to the threshold potential. B The action potential of the membrane approaches zero.

Simply so what is depolarization of a neuron. Neurotransmitters are released from the dendrites. During an action potential the depolarization is so large that the potential difference across the cell membrane briefly.

Which of the following will occur when a neuron depolarizes-Neurotransmitters are released from the dendrites-The refractory period of the neuron will prevent it from firing-The neuron will polarize-The neuron will return to resting potential-The neuron will fire an action potential. One symptom of Multiple Sclerosis MS is an exaggerated pupillary light reflex. B Three presynaptic neurons synapse with one postsynaptic neurons.

Which of the following will occur when a neuron depolarizes. When one of the presynaptic neurons fires rapidly in quick succession the postsynaptic neuron depolarizes. The refractory period of the neuron will prevent it from firing.

In the process of depolarization the negative internal charge of the cell temporarily becomes more positive less negative. Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neurons membrane while depolarization is when the membrane potential becomes less negative more positive. The entire process occurs when the cell allows specific ions to flow into and out of the cell.

The neuron will return to resting potential. As a result the inner portion of the nerve cell reaches 40 mV. The neuron will polarize.

Motor neuron depolarizes 2 Sensory neuron depolarizes 3 Interneuron depolarizes 4 Light receptors are stimulated The order in. The neuron will fire an action potential. C One presynaptic neuron synapses with one postsynaptic neurons.

Depolarization occurs when a stimulus reaches a resting neuron. Deterioration of dopamine producing neurons. Its cytoplasm become more negative and its plasma membrane becomes more positive Its neurotransmitters becomes more positive and its nucleus becomes more negative Its cytoplasm becomes more positive and its plasma membrane becomes more negative Its neurotransmitters become more.

Which of the following occurs when a neuron depolarizes. Which of the following occurs during depolarization. When two of the presynaptic neurons fire at the same time the postsynaptic neuron depolarizes.

Which of the following occurs when a stimulus depolarizes a neurons membrane to a membrane potential below the voltage threshold. The action potential approaches zero. Motivation reward alertness learning emotion.

Depolarization occurs when a stimulus reaches a resting neuron. This shift from a negative to a more positive membrane potential occurs during several processes including an action potential.
