Eosinophils
Eosinophils are specialized white blood cells that participate in inflammatory processes such as allergic diseases. They also are involved in tissue repair and remodeling. In healthy people, eosinophils comprise approximately 1 to 6 percent of white blood cells. The body may produce more of these cells in response to parasitic and fungal infections. Certain allergic […]
Fracture
An injury that upon assessment is painful, swollen, and deformed. A break of a bone.
Hematopoiesis
The production and development of blood cells, normally in the bone marrow.
Lymphopenia
Lymphopenia (also known as lymphocytopenia) is a disorder in which your blood doesn’t have enough white blood cells called lymphocytes. These cells are made in the bone marrow along with other kinds of blood cells. Lymphocytes help protect your body from infection. Low numbers of lymphocytes can raise your risk of infection.

Myeloid Cells
Granulocytes and monocytes, collectively called myeloid cells, are differentiated descendants from common progenitors derived from hematopoietic stem cells in the bone marrow. Commitment to either lineage of myeloid cells is controlled by distinct transcription factors followed by terminal differentiation in response to specific colony-stimulating factors and release into the circulation. Upon pathogen invasion, myeloid cells […]
Osteoblast
A cell derived from mesenchymal cells. It manufactures bone matrix.
Platelet
A round or oval disk, 2 to 4 μm in diameter, found in the blood of vertebrates. Platelets number 130,000 to 400,000/mm3. They are fragments of megakaryocytes, large cells found in the bone marrow.
T Cells
A type of white blood cell. T-lymphocytes are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and may help fight cancer. Source: NIH.gov
White Blood Cell
Any of several kinds of colorless or nearly colorless cells of the immune system that circulate in the blood and lymph. Leukocytes comprise granulocytes and agranulocytes. Neutrophils, 55% to 70% of all leukocytes, are the most numerous phagocytic cells and are a primary effector cell in inflammation. Eosinophils, 1% to 3% of total leukocytes, destroy […]
