When your brain senses stress, it activates your autonomic nervous system.

当你的大脑感受到压力时，它会激活你的自主神经系统。

The supervisors of this process are those osteocytes, which kick things off when they sense stress and strain, or respond to mechanical stimuli, like the weightlessness of space, or the impact of running on pavement.

这个过程的监督者是那些骨细胞，当它们感觉到压力和应变时，它们会启动东西，或者对机械刺激做出反应，比如太空的失重，或者在人行道上跑步的影响。
