During inspiration, the volume of the lungs is actively increased by the action of the diaphragm. As the volume of the lungs increases, the pressure within the lungs falls about 1 mmHg below atmospheric pressure. Air rushes into the lungs due to this pressure difference.

5. The N pole faces of two cylindrical neodynium magnets having a radius of 0.5 cm and a length of 20 cm are brought together so that their faces are parallel and there is a small gap between them. The magnetic surface charge density on each pole face is 2 x 10° Cm's. (a) What is the force between the magnets in the limit in which the gap goes to zero? -Assume that the magnets are much longer than shown in the figure below, so that you only need to concern yourself with the repulsion between N and N. (b) What is the force between the magnets when they are separated by 0.5 m? At this separation you can approximate the four pole faces as point-charges.

In an experiment you artificially cut in half (-50% reduction) the number of voltage gated sodium channels that are located on the membrane of the axon hillock. 1.) Which of the following is the most likely result of this experimental manipulation? A. Summation of more IPSPS would be required for an action potential to occur B. This change would have no effect on the value required to reach threshold C. Even with a very large number of summating EPSPS it would be impossible for an action potential to occur D. The value to reach threshold would be higher (more positive) making it less likely for an aetion potential to occur E. All of the above statements are FALSE The made-up drug Jeakyhoss degrades myelin resulting in myelin becoming more porous and therefore a poor insulator. 2.) Which of the following would NOT be an effect of leakykose? A. Propagation of the action potential would likely alow B. The action potential may degrade because it can't properly be regenerated C. The action…
