骨骼系統

Also known as skeletal system, bones

A skeleton is the structural frame that supports the body of most animals. There are several types of skeletons, including the exoskeleton, which is a rigid outer shell that holds up an organism's shape; the endoskeleton, a rigid internal frame to which the organs and soft tissues attach; and the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids.

AI overview

A skeleton is the structural frame that supports an animal's body, and different animals have different types depending on their needs. The three main types are the exoskeleton (a rigid outer shell), the endoskeleton (a rigid internal frame inside the body), and the hydroskeleton (a flexible structure supported by fluid pressure).

骨骼（bone）简称骨，是組成脊椎動物內骨骼的堅硬器官，功能是運動、支持和保護身體，及儲藏礦物質。骨組織是一種密實的結締組織。骨骼由各種不同的形狀組成，有複雜的內在和外在結構，使骨骼在減輕重量的同時能夠保持堅硬。骨骼的成分之一是礦物質化的骨骼組織，其內部是堅硬的蜂巢狀立體結構；其他組織還包括了骨髓、骨膜、神經、血管和軟骨。人體的骨骼具有支撑身体的作用，其中的硬骨組織和軟骨組織皆是人體結締組織的一部分（而硬骨是結締組織中唯一較為堅硬的）。成人有206塊骨頭，新生儿有大約300塊。由於諸如頭骨會隨年紀增長而癒合，因此成人骨骼個數少一兩塊或多一兩塊都是正常的。另外，成人有28~32個牙恆齒，多的一般稱為智齒，小孩乳齒20顆。骨与骨之間的間隙一般稱之為關節，除了少部分的不動關節可能以軟骨連接之外，大部分是以韌带连接起來的。關節可分成不動關節、可動關節以及難以被歸類的中間型可稱為少動關節。光有骨骼是不具有讓身體運動的作用的，一般俗稱的“運動系統”（這種分類稱呼其實是不嚴謹的，因為通常骨骼已經可以被稱做骨骼系統，包含軟骨、硬骨以及連結骨與骨的韌帶，甚至包含關節部分（關節液，因為關節是位置不是細胞更不是組織）。所謂的運動系統，應該是被譯作「」的 super system 之一，人體一般分為六種 super system）還包含了肌肉（骨骼肌）系統。骨骼肌是橫紋肌，可隨意志伸縮，一般一種「動作」是由一對肌肉對兩塊骨頭（一個關節）作，而肌肉末端以肌腱和經過關節的下一個骨頭連接。其實韌帶和肌腱也是結締組織，所以運動（超）系統中只有肌肉組織跟結締組織，頂多再包含骨髓內的神經及控制肌肉的運動神經屬於神經組織。
