  2. Medullary cavity - Wikipedia

    en.wikipedia.org/wiki/Medullary_cavity

    Located in the main shaft of a long bone (consisting mostly of compact bone), the medullary cavity has walls composed of spongy bone (cancellous bone) and is lined with a thin, vascular membrane . [1] [2] This area is involved in the formation of red blood cells and white blood cells, and the calcium supply for bird eggshells. The area has been ...

    en.wikipedia.org/wiki/Anatomical_terms_of_bone

    The cortex of a bone is used to refer to its outer layers, and medulla used to refer to the inner surface of the bone. Red marrow , in which blood is formed is present in spongy bone as well as in the medullary cavity , while the fatty yellow marrow is present primarily in the medullary cavity.

  4. Endosteum - Wikipedia

    en.wikipedia.org/wiki/Endosteum

    The endosteum (pl.: endostea) is a thin vascular membrane of connective tissue that lines the inner surface of the bony tissue that forms the medullary cavity of long bones. [1] [2] This endosteal surface is usually resorbed during long periods of malnutrition, resulting in less cortical thickness. [citation needed]

  5. Long bone - Wikipedia

    en.wikipedia.org/wiki/Long_bone

    The long bones of the human leg comprise nearly half of adult height. The other primary skeletal component of height are the vertebrae and skull. The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy ...

  6. Clavicle - Wikipedia

    en.wikipedia.org/wiki/Clavicle

    The cancellous bone forms via two ossification centres, one medial and one lateral, which fuse later on. The compact forms as the layer of fascia covering the bone stimulate the ossification of adjacent tissue. The resulting compact bone is known as a periosteal collar. The collarbone has a medullary cavity (marrow cavity) in its medial two ...

  7. Periosteum - Wikipedia

    en.wikipedia.org/wiki/Periosteum

    The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.) Endosteum lines the inner surface of the medullary cavity of ...

  9. Bone marrow - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow

    Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a man weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow. [5] Human marrow produces approximately 500 billion blood cells per day, which join the systemic circulation via permeable vasculature sinusoids within the medullary cavity. [6]
