There are many, possibly infinite, potential actions that you can take at any moment.

在任何时刻，你都可以采取很多或许可以说是无穷尽的潜在行动。

Myelin is extremely important to neurons, because it helps to allow an action potential to propagate much faster.

髓鞘对于神经元十分重要，因为它可以极大地加速动作电位的传播。

My brain sends an action potential along the motor neuron until it synapses with a muscle cell in my arm.

我的大脑沿着运动神经元发送动作电位，直到它与我手臂上的肌肉细胞突触。

Since chloride has a negative charge, it makes the inside of a cell more negative, and that inhibits an action potential.

由于氯离子带负电，这可导致细胞内负电荷积聚，来抑制动作电位。

Since calcium has a positive charge, it makes the inside of the cell more positive, and that helps trigger an action potential.

由于钙离子带正电，这可导致细胞内正电荷积聚，来触发动作电位。

But in order for it to become an action potential again in the receiving neuron, it has to be converted back to electrical.

但是为了让它在接收神经元中再次成为动作电位，它必须被转换回电位。

We've even seen an action potential in a human.

我们甚至已经在人类身上看到了动作电位。

That is an action potential that is happening inside the plant.

这是植物内部发生的动作电位。

The upper peaks that we see are ares for potential action.

我们看到的上峰是潜在行动的区域。

Stimulus is required to generate an action potential.

需要刺激来产生动作电位。

But, of course, it is not really the end of it for Andrew Cuomo. He is facing potential civil actions from some of these women.

当然，对安德鲁·科莫来说，事情还没有真正结束。该事件中的一些女性可能会对他提起民事诉讼。

The Chinese say they’re ready for any potential protectionist actions and that their economy would remain strong.

中国人表示， 他们已准备好采取任何潜在的保护主义行动，并且他们的经济将保持强劲。

So even if the brain sends a signal, the muscle cell can’t generate the action potential necessary to contract.

因此， 即使大脑发出信号，肌肉细胞也无法产生收缩所需的动作电位。

For example, here I am predicting the action potentials, or the spikes, that are fired by one of these neurons when the dragonfly sees the prey move.

例如，我在这里预测当蜻蜓看到猎物移动时，其中一个神经元发射了动作电位或脉冲。

Membrane voltage becomes less negative, moving closer to the threshold potential, making it EASIER to initiate an action potential.

膜电压具有较小负值，接近阈值电位，这样，更容易启动动作电位。

Well, rewind your brain to when we explored the electrical marvel that is the action potential, and how it triggers both neurons and muscle cells.

好吧，让我们回过头来看我们探索过的电奇迹动作电位，以及它是如何触发神经元和肌肉细胞的。

An ECG is a composite recording of all the action potentials produced by the nodes and the cells of the myocardium.

ECG是由结点和心肌细胞产生的所有动作电位的综合记录。

Once the integration center interprets the signal, it transmits the message to motor neurons, which send an action potential back down your leg, where it reaches an effector.

一旦整合中心解释了信号，它就会将信息传输到运动神经元，运动神经元将动作电位发送回你的腿，到达效应器。

It's largely a matter of control. With such a direct connection between cells, an action potential in one neuron will generate an action potential in the other cells across the synapse.

这在很大程度上是一个控制问题。有了细胞之间的这种直接连接，一个神经元中的动作电位将在突触上的其他细胞中产生动作电位。

Since some of these neurons can be very long, especially ones that go from the spinal cord to the toes, the fact that myelin helps speed up action potentials is super important.

由于一些神经元非常长，例如有些神经元从脊髓一直延伸至脚趾，所以髓鞘的加速效果十分重要。
