In fact, you have a lot more.Like nociception, which is the sense of pain, and proprioception, the sense of how our body are positioned.Not to mention the sense of balance, temperature and passing of time.

实际上，要多得多。比如感觉疼痛“伤感感受”，以及用于调节位“本感受”。其他还有感觉平衡 温度和时间流逝感受等。

There are actually two phenomena at play: the experience of pain, and a biological process called nociception.

疼痛和一种叫伤害生。

Until recently, we thought the glial cells surrounding neurons were just support structures, but now we know they have a huge role in influencing nociception.

直到最近，我们还认为神经元周围胶质细胞只是支持结构，但现在我们知道它们在影响伤害性方面有着巨大作用。

But there are a whole set of factors besides nociception that can influence the experience of pain and make pain less useful.

但是除了伤害之外，还有一系列因素可以影响疼痛，使疼痛变得不那么有用。

Psychological factors clearly play a role in pain too, potentially by influencing nociception and by influencing the brain directly.

心理因素也可能通影响伤害感受和直接影响大脑而在疼痛中发挥作用。

So an oyster may recoil when squirted with lemon juice, for instance, because of nociception.

因此，比如牡蛎在被喷上柠檬汁时可能会退缩，这便是痛觉传导作用。
