The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

Discussion and Conclusions Many obstacles to my potential strategy are worth overcoming. Since the brand new policy is to add extra taxes on smoking and fining the smoking companies for their actions‚ then one is able to make sure that people comply or go out of business. A way to overcome the challenges is to have someone from each company represented in Congress (Kottke‚ RN‚ GH‚ & ML.‚ 1988). This may mean making sure that there is someone in government that is passionate about this issue‚

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

Analysis of Dramatic Conflicts Under Different Models of Societies Ever since Hu Shi introduced Ibsen’s play A Doll’s House to China and wrote his first play The Main Event in Life in 1919‚ Chinese culture and society started to accept modern spoken drama and it marked as the beginning that Chinese modern spoken dram became one of the alternatives to the traditional Chinese drama. However‚ although the history of Chinese modern spoken drama is not too long‚ the changes in the historical contexts

Action Potentials An action potential is the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. An action potential occurs when a neuron sends information down an axon‚ away from the cell body. A threshold is the minimum amount of stimulation needed to start a neural impulse (you know‚ the electrical impulses that travel throughout your body carrying important information). Action potentials generated by neural impulses are

DISCUSSION QUESTIONS‚ CASE INTRODUCTION AND KEY POINTS Introduction Under Armour’s rapid rise in the sports apparel industry under its founder and CEO Kevin Plank has surprised many. Plank has turned a company that he started in his grandmother’s basement into a powerful opposing force to Nike. The company’s competitive advantage comes through its focus on performance‚ and its products have been well received by athletes. The company currently enjoys a strong position as professional athletes

of students‚ I believe all children are not born with the same level of intelligence‚ but all children have the capacity to learn. I do not think that children are born entirely good or entirely bad. A child is influenced by his surroundings‚ and models his behavior to match the people closest to him. Knowledge is relative‚ and the level of success a child achieves in school is directly correlated to the amount of support and encouragement he or she receives at home.
