PREP
, A neuron is placed in a dish with the appropriate medium. d. It would not reach the normal resting membrane potential
What would happen to the resting membrane potential if the
sodium-potassium pumps are blocked?
a. Increase (a greater negative charge- hyperpolarization)
b. Decrease (a smaller negative charge- depolarization)
c. No change from the resting membrane potential when the
pump is active
d. It would not reach the normal resting membrane potential
Does the resting membrane potential increase or decrease if a. Increase (a greater negative charge- hyperpolarization)
we decrease the concentrations of extracellular K+?
a. Increase (a greater negative charge- hyperpolarization)
b. Decrease (a smaller negative charge- depolarization)
c. No change from the resting membrane potential when the
pump is active
d. There would be no resting membrane potential

2. interneuron
3. motor neuron
4. sensory neuron
5. sensory receptor
