骨は主に結合組織で構成されており、これは体に支持と構造を提供する組織の一種です。さらに、骨には骨髄、血管、神経、および骨を修復および維持する生きた細胞も含まれています。背骨は椎骨と呼ばれる一連の小さな骨で構成されています。これらの骨は互いに積み重なって、体を支え、脊髄を保護する脊柱を形成します。脛骨は、すねの骨としても知られており、脚にあります。これは下腿にある2つの主要な骨の1つであり、もう1つは腓骨です。脛骨は2つの中で大きく、より強力です。肋骨は主に、心臓や肺などの胸部の重要な臓器を保護する役割を果たします。さらに、背骨に接続された肋骨は、上半身を支え、呼吸運動を可能にする上で重要な役割を果たします。骨髄は、多くの骨の中心にある柔らかい海綿状組織です。赤血球、白血球、血小板などの血球を生成するために不可欠です。脚の大腿骨や脛骨、腕の上腕骨や橈骨などの長骨は、主に支持と耐荷重のために設計されています。それらは動きに不可欠であり、筋肉の付着に必要な構造を提供します。関節は、2つ以上の骨が接する点です。関節は動きを可能にし、機械的なサポートを提供します。頭蓋骨のように動かないものもあれば、膝や肘のように非常に可動性の高いものもあります。通常、骨として分類されませんが、歯のエナメル質は人体で最も硬い物質です。各歯の保護外層を形成し、噛んだり咀嚼したりするなどの日常的な摩耗に耐性があります。靭帯は、骨と骨をつなぐ線維性の結合組織です。たとえば、膝では、前十字靭帯と後十字靭帯が大腿骨(太ももの骨)と脛骨(すねの骨)をつなぎ、関節を安定させるのに役立ちます。骨化とは、体が組織(最初は軟骨)を骨に変換する骨形成の過程です。このプロセスは、成長と発達に不可欠ですが、骨が成長して修復するにつれて、生涯にわたって発生します。踵骨、またはかかとの骨は、足の中で最大の骨です。立っているときは体重のほとんどを支え、足を動かす筋肉のてこを提供します。舌骨は首にあります。このU字型の骨は、他の骨と直接関節していないため、ユニークです。嚥下と発話に関連する筋肉の付着を提供します。骨芽細胞は骨形成細胞です。骨化として知られるプロセスで、新しい骨素材の生成を担当します。これらの細胞は、骨の成長と治癒の両方において重要な役割を果たします。肩甲骨は、肩甲骨とも呼ばれ、上腕骨(上腕の骨)と鎖骨(鎖骨)をつなぐ骨です。肩甲帯の一部であり、上腕の可動性を可能にします。骨粗鬆症は、骨が弱くなり骨折しやすくなる骨疾患です。この骨密度の低下は、多くの場合、加齢、ホルモンの変化、カルシウムまたはビタミンDの欠乏の結果です。You scored 0 out of 15You scored 1 out of 15You scored 2 out of 15You scored 3 out of 15You scored 4 out of 15You scored 5 out of 15You scored 6 out of 15You scored 7 out of 15You scored 8 out of 15You scored 9 out of 15You scored 10 out of 15You scored 11 out of 15You scored 12 out of 15You scored 13 out of 15You scored 14 out of 15You scored 15 out of 15
