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. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pelvis. [4]
A megakaryocyte (from mega- 'large' karyo- ' cell nucleus ' and -cyte ' cell ') is a large bone marrow cell with a lobated nucleus that produces blood platelets (thrombocytes), which are necessary for normal clotting. In humans, megakaryocytes usually account for 1 out of 10,000 bone marrow cells, but can increase in number nearly 10-fold ...
A megakaryoblast (from mega- 'large' karyo- ' cell nucleus ' and -blast ' precursor cell ') is a precursor cell to a promegakaryocyte. During thrombopoiesis, the promegakaryocyte matures into the form of a megakaryocyte. From the megakaryocyte, platelets are formed. [1] The megakaryoblast is the beginning of the thrombocytic series or platelet ...
Diagram of a typical long bone showing both cortical (compact) and cancellous (spongy) bone. Haversian canals[i] (sometimes canals of Havers, osteonic canals or central canals) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves to travel through them to supply the osteocytes.
At the time, Maycie Fuselier — who signed up to be a bone marrow donor three years prior — ultimately got a phone call letting her know that she was a match for Sophie. "I was like, oh my gosh ...
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass ...
Intraosseous infusion (IO) is the process of injecting medication, fluids, or blood products directly into the bone marrow; [1] this provides a non-collapsible entry point into the systemic venous system. [2] The intraosseous infusion technique is used to provide fluids and medication when intravenous access is not available or not feasible.
Bone marrow transplants can be life-saving for patients suffering from certain types of cancer, blood disorders and other diseases — but for many patients, finding a match can take months or ...
