Steps leading to an Action Potential n Neuron at rest ¨ Na+ ions on the outside ¨ K+ ions on the inside ¨ Resting potential is -70mV

n Neuron receives chemical information from other neurons at the synapse ¨ Neurotransmitters (NT) leave the terminal button moving across the synaptic cleft and attach to receptors on the dendrites ¨ If the NT causes the chemically dependent receptor channels to open, allowing Na+ into the neuron, the neuron becomes MORE positive (depolarized)

n When the cell body becomes depolarized, the neuron will send (fire) an action potential n The action potential is the electrical impulse (signal) that is carried down the length of the axon n The electrical impulse causes vesicles of NT in the terminal button to fuse to the membrane to be released, thus affecting the next neurons

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
