They transmit signals down their axons by way of electrical impulses, or action potentials.

它通过子脉冲或动作把信号向下传递给神经轴突。

These compounded factors can raise the speed of an action potential as high as 432 kilometers per hour.

这些复合因素可以将动作提速至每小时 432 公里。

So now we've paused on one motor action potential that's happening right now inside of your brain.

我暂停此时此刻正你脑内的一个运动势。

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的传播。

As you're listening to a chorus of action potentials.

当您正聆听动作的合唱时。

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

这是植物内部发生的动作。

OK. So here we see an action potential encoding information to move. Alright?

好的。 所以这里我看到了动作编码信息的移动。 好吧？

What do we get? We get a beautiful action potential.

我得到什么？ 我获得了漂亮的动作。

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，这可导致细胞内负荷积聚，来抑制动作。

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

我甚至已经人类身上看到了动作。

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，这可导致细胞内正荷积聚，来触发动作。

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。

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

膜压具有较小负值，接近阈值，这样，更容易启动动作。

Stimulus is required to generate an action potential.

需要刺激来产生动作。

It has touch receptors that are sending that information back down in the form of an action potential.

它有触觉感受器，以动作的形式将信息传回。

Most symptoms of acute hypocalcemia can be attributed to the effect, it has on action potential generation in neurons.

急性低钙血症的大多数症状可归因于其对神经元动作产生的影响。

Action potentials can travel as quickly as 100 meters per second, which is about 224 miles per hour for us non-metric system users.

动作可以以每秒 100 米的速度传播，对于我非公制用户来说大约是每小时 224 英里。

Nerve fibers are either dendrites that receive signals from other neurons, or axons that send signals called action potentials along to other neurons.

神经纤维，包括从别的神经元接收信号的树突，和向别的神经元发送动作信号的轴突。

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

但是为了让它接收神经元中再次成为动作，它必须被转换回。

A decrease in blood pressure causes a decrease in action potentials sent to the cardio regulatory center of the medulla.

血压降低导致发送到延髓心脏调节中心的动作降低。
