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.

当你的大脑被甩动和挤压时，扭曲的力量会最小程度上发生，使神经细胞变形和撕裂，受损的神经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，流突涌入侧，牵拉壁使内皮细胞变形，刺激壁产生生长因子，如内皮生长因子（VEGF）。

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

它用于制作种名为鲎变形细胞裂解物或 LAL 的混合物。

But horseshoe crab amebocytes are exceptionally sensitive to bacterial endotoxins.

而，帝王蟹的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的大型复杂生物是多细胞的，而不是高达6英尺的单细胞变形虫团块。
