EP88 死靈使來了?「死靈魔」蜘蛛軀幹的妙用! 粉絲專頁:https://www.facebook.com/scientists543/ 美國Rice大學機械工程系的Preston教授在實驗室裡面發現一支死蜘蛛,「死蜘蛛」的腳向內捲縮成一團。 Preston教授研究了蜘蛛的運動方式,發現蜘蛛沒有「讓腳伸展的肌肉」而只有「讓腳縮起來的肌肉」。 當牠活著時,要如何讓腳伸展開來呢? 蜘蛛利用體腔收縮而使「血壓上升」時,腳就會因壓力增加而向外伸展;反之「血壓下降」時,腳就會向內捲縮起來。 蜘蛛的腳的動作,除了肌肉以外,主要是靠「液壓系統」在動作的。 本集以發表於2022/07/25的「先進科學」的研究,聊聊「死靈魔」蜘蛛軀幹的妙用。 #蜘蛛#死靈使#機械工程 -- Hosting provided by SoundOn
