Correct Statements About Compact Bone:<\/h3>\n\n\n\n

  1. It forms the external walls of a long bone.<\/strong> \u2705<\/li>\n\n\n\n
  2. It is solid and relatively dense.<\/strong> \u2705<\/li>\n<\/ol>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n

    Compact bone, also known as cortical bone<\/strong>, is one of the two main types of bone tissue in the skeletal system, the other being spongy bone (cancellous bone)<\/strong>. Compact bone plays a crucial role in providing structure, strength, and protection to bones.<\/p>\n\n\n\n

    1. It Forms the External Walls of a Long Bone<\/strong><\/h4>\n\n\n\n

    Compact bone primarily makes up the outer layer<\/strong> of long bones, such as the femur, humerus, and tibia. This dense layer of bone provides protection and structural integrity to the bone, allowing it to withstand mechanical stress and weight-bearing forces. The diaphysis (shaft) of a long bone<\/strong> is composed mostly of compact bone, which gives it durability and resistance to bending and breaking.<\/p>\n\n\n\n

    2. It Is Solid and Relatively Dense<\/strong><\/h4>\n\n\n\n

    Unlike spongy bone, which has a porous structure, compact bone is highly dense. It consists of osteons (Haversian systems)<\/strong>, which are cylindrical structures that contain concentric layers of calcified matrix, called lamellae<\/strong>, surrounding a central canal. These central canals contain blood vessels and nerves that supply nutrients to bone cells (osteocytes<\/strong>). This dense organization makes compact bone extremely strong, capable of withstanding significant forces.<\/p>\n\n\n\n

    Incorrect Statements:<\/strong><\/h4>\n\n\n\n
      \n
    • “In flat bones, it is called diplo\u00eb.”<\/strong> \u274c\n
        \n
      • Incorrect. The term diplo\u00eb<\/strong> refers to the spongy bone found between two layers of compact bone in flat bones<\/strong>, such as the skull.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • “It contains trabeculae.”<\/strong> \u274c\n
          \n
        • Incorrect. Trabeculae<\/strong> are found in spongy bone<\/strong>, not compact bone. Trabeculae are the thin, web-like bony structures that help reduce bone weight while maintaining strength.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • “It is porous.”<\/strong> \u274c\n
            \n
          • Incorrect. Compact bone is not porous; it is dense and solid, unlike spongy bone, which has numerous open spaces.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
