Question

question 4 1 pts the sodium - potassium pump actively pumps three potassium ions out of the neuron and two sodium ions into the neuron. true false question 5 1 pts the difference in electrical charge between the inside and outside of a membrane is called the membrane potential. true false question 6 1 pts the action potential seems to \leap\ from node to node along a myelinated fiber. this type of impulse regeneration is called __________ conduction. sensory refractory saltatory action potential

Explanation:

• Question 4: The sodium - potassium pump actively pumps three sodium ions out of the neuron and two potassium ions into the neuron, so the statement is false.
• Question 5: By definition, the difference in electrical charge between the inside and outside of a membrane is called the membrane potential, so this statement is true.
• Question 6: The action potential that "leaps" from node to node along a myelinated fiber is called saltatory conduction.

Answer:

• Question 4: B. False
• Question 5: A. True
• Question 6: C. saltatory
