12. Let us consider another artificial case. Now only sodium channels open. Potassium channels are closed. Indicate sodium ion distribution across the cell membrane. Why sodium concentration inside the cell does not get equal to the sodium concentration outside the cell over time? Explain the mechanism on the microscopic level. Explain the mechanism on the macroseopic level using voltage across the cell membrane.

3. Explain all the electrical and mechanical events which occur during each measured wave, segment andinterval. An electrical event would be membrane polarization: depolarization, repolarization, restingmembrane potential, hyperpolarization etc; mechanical events include blood flow, open or closed valves,heart sounds, contraction, relaxation, pressure changes, etc. An example of a complete answer for the P waveis given below. Feel free to use your lecture and/or textbook as a reference to make the connections betweenECG and the cardiac cycle. This is a great way to review for the exam and apply what you are learning. P Wave – During the P wave, depolarization is sweeping from the SA node throughout both atria (electricalevent). This leads to the beginning of atrial contraction (mechanical event).PR Interval -P-R Segment –QRS Complex –Q-T Interval –S-T Segment –T Wave –T-P Segment –R-R Interval –
Which of the following means the ability to transmit electrical current from one cell to another? A. Conductivity B. Excitability C. Contractility D. Automaticity
In 2003, the Nobel Prize in Physiology or Medicine was awarded to Paul C. Lauterbur and Sir Peter Mansfield for discoveries related to magnetic resonance imaging (MRI). This is a tool to see the structures of the body (not just the nervous system) that depends on magnetic fields associated with certain atomic nuclei. The utility of this technique in the nervous system is that fat tissue and water appear as different shades between black and white. Because white matter is fatty (from myelin) and gray matter is not, they can be easily distinguished in MRI images. Visit the Nobel Prize website (http://openstaxcollege.org/l/nobel_2) to play an interactive game that demonstrates the use of this technology and compares it with other types of imaging technologies. Also, the results from an MRI session are compared with images obtained from x-ray or computed tomography. How do the imaging techniques shown in this game indicate the separation of white and gray matter compared with the freshly dissected tissue shown earlier?
After an action potential, the opening of additional____voltage-gated ____ channels and The inactivation of sodium channels, cause the membrane to return to its resting membrane potential. sodium potassium calcium chloride
The major role of the Na+/K+ pump is to: a. cause a rapid firing of the action potential so the inside of themembrane becomes momentarily positive. b. decrease the resting membrane potential to zero. c. hyperpolarize the membrane above resting value. d. cause an action potential to enter a refractory period. e. maintain the resting membrane potential at a constantnegative value.
Assume that a membrane permeable to Na+ but not to Cl- separates two solutions. The concentration of sodium chloride on side 1 is higher than on side 2. Which of the following ionic movements would occur? a. Na+ would move until its concentration gradient is dissipated (until the concentration of Na+ on side 2 is the same as the concentration of Na+ on side 1). b. Cl- would move down its concentration gradient from side 1 to side 2. c. A membrane potential, negative on side 1, would develop. d. A membrane potential, positive on side 1, would develop. e. None of the preceding is correct.

1. hyponatraemia occurs when serum sodium levels drop too much. Why do you think drinkingdeionized water would result in low blood sodium levels? (Think about solute diffusion)2. Think back to the concepts we learned in lecture. Explain why low serum sodium levelswould cause water to move into brain cells.3. According to the article, was the individual's excessive water intake related to physiologicalor psychological symptoms? Explain your reasoning4. What could have the individual added to her water to prevent this from happening, and whywould this have prevented hyponatraemia? Incorporate your knowledge of concentrationgradients and diffusion.5. Over-hydration can be treated if caught in its early stages. What do you think would be thequickest way to restore the patient's serum sodium levels?

Which of the following is ther eason why the potassium leaves the cell readily at the peak of the action potential?A) The sodium-potassium pumps work hard to return potassium to the extracellular fluid. B) Diffusion will continue to push potassium into the cell, but electrostatic pressure will move potassium out of the cell. C) Diffusion will push potassium out of the cell, but electrostatic pressure continues to attract potassium to the interior of the cell. D) Both diffusion and electrostatic pressure will cause potassium to exit the cell.
