Question
5. Repolization takes places when K+ ion move out from the cell or efflux of K+ ion. Hence, option b is correct.
6. Neurons that convey motor commands to the bladder are known as visceral motor. Hence, option a is correct.
7. Hyperpolarization is the state of relative refractory period. Hence, option a is correct.
9. During depolarization, the Na+ activation gates are open. Hence, option b is correct.
10. The cell body of unipolar sensory neurons is situated in the outside CNS. Hence, option b is correct.

However, the potassium overshoots and causes Question 5 2 pts During the refractory period, the pumps Na+ ions out of the cell and K+ions into the cell, re-establishing the resting membrane potential and concentration gradient.

The right answer is (D)
Please explain. I don't understand how K+ could be effluxing rather
than influxing
Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

Question 49 1.67 pts Neurons have a negative resting potential. When they are conducting an action potential, the resting potential becomes more positive (depolarization) followed by a drop in the resting potential (repolarization). What is the order and direction of the ion movement responsible for these changes? Potassium (K+) rushes out, then sodium (Na+) rushes into the cell Chloride (Cl-) rushes out, then potassium (K) rushes into the cell Potassium (K+) rushes in, then sodium (Na+) rushes out of the...
