28 wrz 2024 · Bone marrow is a soft, spongy tissue found within the hollow cavities of bones. It is a crucial component of the body's hematopoietic system, responsible for producing blood cells. Bone marrow exists in two forms: red marrow, which is active in hematopoiesis (blood cell formation), and yellow marrow, which primarily stores fat and can convert
30 paź 2023 · This article will review the embryology of the bone marrow as well as its histology. Additionally, the constituent cell lineages and their function will be discussed, together with clinically relevant processes and pathologies.
Structure and Gross Anatomy. The vascular section and non-vascular sections make up the bone marrow. The vascular part features blood vessels that provide nutrients to the bone and transport blood stem cells and fully formed blood cells from the bone into circulation. The non-vascular part is where haematopoiesis (blood cell creation) occurs.
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
5 paź 2019 · Bone marrow is the soft, flexible connective tissue within bone cavities. A component of the lymphatic system, bone marrow functions primarily to produce blood cells and to store fat. Bone marrow is highly vascular, meaning that it is richly supplied with a large number of blood vessels.
19 cze 2016 · Bone marrow is a red, soft, semisolid, gelatinous, mesenchymal-derived tissue occupying the medullary cavities of the axial skeleton. It is composed of hematopoietic cells and bone marrow stroma. The medullary cavity is protected by subcortical and cortical bone, which in turn is covered by periosteum (Fig. 1.1).
10 paź 2024 · Bone marrow is a spongy organ that fills the center of various bones of your body. It is where stem cells produce red and white blood cells and platelets. Without bone marrow, you couldn't move oxygen through your body or fight infections, and blood wouldn't clot.
