So it makes sense that the smooth muscle around your blood vessels, which feed your skeletal muscles — which you'll need to get out of that smoky house — are covered in beta receptors.
所以血管周围的平滑肌是有道理的,它滋养你被β受体覆盖的骨骼肌——你需要骨骼肌来帮你走出烟雾弥漫的房子。

Crash Course 解剖生理学篇 So it makes sense that the smooth muscle around your blood vessels, which feed your skeletal muscles — which you'll need to get out of that smoky house — are covered in beta receptors. 所以血管周围的平滑肌是有道理的,它滋养你被β受体覆盖的骨骼肌——你需要骨骼肌来帮你走出烟雾弥漫的房子。 Crash Course 解剖生理学篇 And you also learned that the same messenger chemical can evoke different responses depending on the receptors, with alpha receptors causing smooth muscles to constrict, for example, while beta receptors cause smooth muscle to relax. 你还了解到,同样的信使化学物质可以根据受体唤起不同的反应,例如,α受体导致平滑肌收缩,而β受体导致平滑肌放松。 Crash Course 解剖生理学篇 But on smooth muscle cells that control other blood vessels, there are lots of beta receptors for epinephrine and norepinephrine, and when they are activated, they make the muscles relax, letting more blood flow through. 但是在控制其他血管的平滑肌细胞上,有许多肾上腺素和去甲肾上腺素的β受体,当它们被激活时,它们使肌肉放松,让更多的血液流过。 |
