Action Potential An action potential‚ also called a spike‚ nerve impulse‚ and discharge‚ is the rapid reversal of charge of the cell membrane. These changes in charge occur within milliseconds‚ meaning the action potential travels very quickly down the axon in order to convey information over long distances. This transfer of information occurs within six phases and requires the presence of multiple pumps and channels embedded in the membrane to control ion concentration. Phase 1: The Resting Phase

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.

CORE 105 Aesthetics: The Artistic Impulse Study Guide Chapter Six: Theatre GENRES • What are the five GENRES of theatre? Describe them. 1.The first genre of theatre is tragedy. Tragedy is what happens when humans try to justify themselves. Their destruction in the attempt creates a wrong or an evil in their surroundings. Tragedy is a play with an unhappy ending. 2.

The reality is that I have this so called “bitch resting face” and when they actually meet me‚ they often look confused since they were expecting for me not to speak

Guts‚ and Brains Seminar Summary During the seminar “Bugs‚ guts and brains: How gut microbiota shapes your mind and body” on November 7‚ Physiologist from UC Davis‚ Dr. Helen Raybould discussed how gut microbes in humans and animals affects neurophysiology based primarily on the foods we eat and the genes expressed in the gut. There is an intersection between micro and host physiology that affects the overall health and behavior of the host. To understand this‚ the neural pathways by which macronutrients

Abstract Purpose: Transcutaneous Posterior Tibial Nerve Stimulation (TPTNS) using adhesive skin electrodes is not commonly used due to its low efficacy. Our objective was to verify whether the combination of TPTNS with low dose Trospium chloride in the treatment of females with overactive bladder (OAB) would be more effective than TPTNS alone after failure of behavioral therapy. Materials and Methods: We randomized 30 women with OAB‚ into two groups‚ 15 patients each: Group I received 30 minutes

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

Beauty and the Creative Impulse This essay‚ out of the three‚ was my favorite. The author had a lot of good points to support her thesis in which she stated that beauty is something integral of the world we live in; the earth that the Creator created. She also brought up the fact that sometimes we move so fast that we take beauty for granted. In this day and age‚ we live our lives in fast forward and we‚ almost literally‚ do not even attempt to stop or even slow down to smell the roses. She
