A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

Cost vs. Worth: The Dilemma of Higher Education As many approach graduation from high school‚ the same question overwhelms a vast majority of young‚ college-hungry graduates: How will I pay for college? Price is no secret when it comes to higher education‚ but shrouded in mystery is the true debate. For while many may think price is the latest hot topic‚ the true debate isn’t actually over price – it’s over worth. Many diverse people with just as diverse opinions present several views to

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
