When your brain gets sloshed and squished, twisting forces happen down on the smallest level, deforming and tearing nerve cells, and damaged neurons can't don't goodly communicate good.

当你大脑被甩动和挤压时，扭曲力量会在最小程度上发生，使细胞变形和撕裂，受损元不能很好地传输信息。

Now, the sudden gush of blood through the collateral vessel stretches its walls and deforms the endothelial cells, which stimulates the production of growth factors like the vascular endothelial growth factor, or VEGF, from the vessel wall.

现在，一股流突涌入侧支，牵拉使内皮细胞变形，刺激产生生长因子，如内皮生长因子（VEGF）。

It's used to make a concoction called Limulus amebocyte lysate or LAL.

它用于制作一种名为鲎变形细胞裂解物或 LAL 混合物。

But horseshoe crab amebocytes are exceptionally sensitive to bacterial endotoxins.

而，帝王蟹变形细胞对细菌内毒素极为敏感。

This is the reason big complex organisms like us are multicellular instead of 6-foot-tall single-celled amoeba blobs.

这就是为什么像我们这样大型复杂生物是多细胞，而不是高达6英尺单细胞变形虫团块。
