Action potentials at the mossy fiber boutons ... and 40 times at 100 Hz were also tested, as shown in Figure 1. For local depolarization, the resting membrane potential was changed by altering the el ...

Read “Let’s get cellular: Teaching cellular action potential with the schoolhouse theory,” and take this quiz to test your knowledge. EMS students can have a difficult time contextualizing ...

Small holes in each cell's membrane, called gap junctions, are juxtaposed so that as the action potential reaches the end of the axon (at the terminal boutons), the depolarization continues across the ...

To test your knowledge, take the quiz: Quiz: Depolarization and polarization — cellular action potential. Carmeliet E, Vereecke J: Adrenaline and the plateau phase of the cardiac action potential.

End plate potentials (EPPs) are the voltages which cause depolarization of skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. They ...

Action Potential: A rapid rise and fall in membrane potential that travels along the neuron, allowing it to communicate with other neurons. Sodium channels are responsible for the rapid depolarization ...

This amplification was greatest when action potentials ... action potential amplification by bath applications of 4-AP. Furthermore, burst firing caused by dendritic depolarization, or following ...

synchronized depolarization within the cerebral gray matter that renders neurons unable to fire action potentials, resulting in widespread neuronal depression. CSD has been observed in stroke, ...

The P wave indicates atrial depolarization. The P wave occurs when the sinus node, also known as the sinoatrial node, creates an action potential that depolarizes the atria. The P wave should be ...

A first-degree AV node block occurs when conduction through the AV node is slowed, thus delaying the time it takes for the action potential ... P wave indicates atrial depolarization (initiated ...
