RESTING POTENTIAL Resting potential is the membrane potential when a neuron is not conducting any electrical impulse or signal. The resting potential is around -75 mV. During resting potential‚ the inside of the axon is negative GRADED POTENTIAL ACTION POTENTIAL Action potential is a fleeting reversal of the membrane potential‚ caused by changes in permeability of the plasma membrane of neuron to potassium and sodium ions causing an electrical impulse to be transmitted along the axon.

What is an action potential? To put it simply‚ it is a message that is sent down the nervous line. The message is written and is sent from the central nervous system. That message is addressed to muscles or glands. This essay will explain what happens before‚ during‚ and after an interneuron action potential. To accurately define an action potential‚ it is part of the incredible course of events that occur during the firing of a neuron. When a neuron is not firing signals‚ the interior of the

Board of Regents of the University of California. The ruling was not a favorable one at first‚ leaving psychologists feeling this would breach their patients trust. Confidentiality is crucial in a therapist-client relationship. “Legislators reacted to therapists’ concerns regarding

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

Achieving and Maintaining Individual Excellence Merriam-Webster’s Dictionary and Thesaurus defines excellence as the quality of superiority. The work excellence is synonymous with distinction‚ greatness‚ flawlessness‚ impeccability‚ and perfection (Merriam-Webster‚ 2006). The pursuit of excellence is the search for perfection. The consensus of today’s society is that nothing is perfect and perfection is unobtainable. Although that may be true‚ I believe that by reaching for excellence‚ or perfection

Walter Miller’s lower-class focal concerns focuses on the traits of the lower-class culture that connects deviance to a distinct normative structure that conflicts with norms of the dominant culture. Miller started a descriptive research strategy to observe lower-class male gang members in their natural habitat. It led Miller to conclude that people of the lower-class show a set of “focal concerns” that categorize them from the mainstream of American society. Miller concluded that people of the

he California Republic was a short-lived‚ unrecognized state that‚ for a few weeks in 1846‚ militarily controlled the area to the north of the San Francisco Bay in the present-day state of California. In June 1846‚ a number of American immigrants in Alta California rebelled against the Mexican department’s government. The immigrants had not been allowed to buy or rent land and had been threatened with expulsion from California because they had entered without official permission. Mexican officials

the Cold War. It displays the fear of a nuclear holocaust between the US and the USSR. I have chosen cultural criticism for this movie. Cultural criticism “focuses on the elements of culture and how they affect one’s perceptions and understanding of texts” (Springboard). In Dr. Strangelove‚ the cold war culture is represented by the display of tension‚ paranoia‚ and the fear of mutual destruction. Because "Dr. Strangelove" features tension‚ paranoia‚ and the fear of mutual destruction‚ it is vital
