Homework Answers
The part I indicates the sodium channels whereas the ii indicates potassium channels .
Potassium channels opened more time than sodium channels because I causes depolarization and ii causes hyperpolarization which need more potassium ions to be ejected from cell and causing more electronegativity inside cells.
Thank you

The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization

After a fraction of a second, K+ voltage gated channels at the site of the original stimulus open. K+ is more concentrated (outside/inside) the cell; therefore, K+ diffused (in/out). This causes the inside of the membrane to become more negative and return to its resting potential of -70 mV. The process is known as (de/re) polarization. In fact, outflow of K+ may be so great that (de/re/hyper) polarization occurs in which membrane potential becomes closer to (-50, -90 ) mV....

Part I—The Hospital At last the day had come. Mr. Th ompson was having his wisdom teeth removed. He was tired of the aches and pains and the sight of his puff y face in the mirror every morning. He felt helpless, lying on the gurney watching the ceiling lights whiz by as he was being wheeled to surgery. Mr. Th ompson had selected this particular oral surgeon because of the sign outside his practice that read: “We cater to...
