At the normal resting potential of a typical neuron, its Na-K ion exchange pump

transmitted? - Answer- whether or not the impulse begins in the CNS
These sensory neurons monitor the digestive, respiratory, cardiovascular, urinary and
reproductive systems. - Answer- interoceptors
The following are the main steps in the generation of an action potential. 1. Sodium
channels are inactivated. 2. Voltage-gated potassium channels open and potassium
moves out of the cell, initiating repolarization. 3. Sodium channels regain their normal
properties. 4. A graded depolarization brings an area of an excitable membrane to
threshold. 5. A temporary hyperpolarization occurs. 6. Sodium channel activation
occurs. 7. Sodium ions enter the cell and depolarization occurs. The proper sequence of
these events is: - Answer- 4, 6, 7, 1, 2, 3, 5

Which of the following about a cell's resting membrane potential is FALSE? - Answer-
The inside of the cell is slightly more positive than outside.
If the cell membrane became freely permeable to sodium ions (Na+), how would the
intracellular environment be affected? - Answer- It would become more positive.
Which type of integral protein allows water and small ions to diffuse through the cell
membrane? - Answer- channel proteins
