Question

question 5 (2 points)
in the context of the neural impulse, which of the following causes the depolarization of neuron membranes?
the inside of the neuron becomes negatively charged because of the excess of calcium ions.
sodium gates open, and sodium ions flow into the neuron.
the outside of the neuron becomes positively charged because of the excess of chlorine ions.
potassium channels open, and potassium ions flow out of the neuron.
question 6 (2 points)
the term ________ refers to the stable, negative charge of an inactive neuron.
depolarized potential
resting potential
action potential
discharge potential

Explanation:

For Question 5, depolarization of neuron membranes occurs when sodium - gated channels open and sodium ions flow into the neuron, making the inside of the neuron more positive. For Question 6, the stable, negative charge of an inactive neuron is called the resting potential.

Answer:

Question 5: Sodium gates open, and sodium ions flow into the neuron.
Question 6: resting potential
