鎖骨與膝蓋痛的力學真相
from 『身體不思議』Amazing Facts of Human Body · host 解剖知識+
附肢骨骼（Appendicular skeleton）包括肩帶與骨盆帶以及上下肢骨骼群。肩帶是由鎖骨和肩胛骨組成，其關節極具活動性，賦予上肢廣泛的活動範圍。每側上肢包含30塊骨頭（肱骨、橈骨、尺骨、腕骨、掌骨及指骨）。相對地，骨盆帶則是由髖骨（髂骨、坐骨與恥骨癒合而成）組成，與中軸骨緊密結合，形成堅固且活動度低的承重結構，主要負責支撐上半身重量並將其傳導至下肢。每側下肢也包含30塊骨頭（股骨、髕骨、脛骨、腓骨、跗骨、蹠骨及趾骨）。整體而言，附肢骨骼不僅使人體能夠執行如抓握等精細動作，還能承受走、跑、跳等移動時的身體重量與衝擊力。留言告訴我你對這一集的想法： Powered by Firstory Hosting
