我们主要通过信号、手势和哑剧动作来交流。

We communicated mainly by signs, gesticulation, and mime.

《柯林斯英汉双解大词典》

并且该系统会不间断的监视伤者的身体条件，任何的变化，比如心跳的急剧加速，那么系统将会给出警报信号——当前的动作应该被取消。

It would also constantly monitor the person's condition and any change - a dramatic rise in heart rate for example - would signal an alert that action needed to be taken.

So action potentials are used by tissues in different ways to send signals from one cell to another or from one end of one cell to another end of the cell.

所以组织以不同的方式利用动作电位,将信号从一个细胞传递到另一个细胞,或从一个神经末梢到另一个神经末梢

Because this post-synaptic neuron is going to be receiving different signals from different cells, it's decision about what to do next, and the what to do next is either create an actual potential or not create an action potential.

因此突触后神经元可以接收,来自不同细胞的不同信号,然后决定后续反应,后续反应包括产生动作电位,或者不产生动作电位
