in adulthood, the red bone marrow is in the shafts of most long bones.
The sternum, ribs, pelvis, vertebrae, and skull bones contain significant amounts of red bone marrow in adults. Red bone marrow is responsible for producing blood cells in the body.
Red bone marrow, which produces blood cells, is found in the spongy bone of long bones, such as the femur.
It lies entirely within the spaces of bone: medullary cavity of young long bones, or spaces of spongy bone
In spongy bone.
sternum
In the marrow cavity of an adult humerus, you would typically find yellow bone marrow, which consists mostly of adipose tissue. Yellow bone marrow stores fat and does not actively produce blood cells unless needed in times of severe blood loss or specific medical conditions.
maxillary canal
No, blood-forming marrow is typically found in the red marrow located in the spongy bone at the ends of long bones (epiphysis) and in flat bones such as the sternum, ribs, pelvis, and skull. The diaphysis of long bones primarily contains yellow marrow, which consists mostly of fat cells.
Normal results of a bone marrow aspiration and biopsy will show a healthy distribution of bone marrow cells including red blood cells, white blood cells, and platelets. Additionally, the marrow should contain the appropriate ratio of different cell types at various stages of maturation. Absence of abnormal cells such as blasts or malignancies is also expected in normal results.
In an adult, red blood cells are primarily produced in the bone marrow, specifically in the spongy or cancellous bone. The bone marrow contains hematopoietic stem cells that give rise to all types of blood cells, including red blood cells.
frontal and parietal bones
pelvic bones
This substance is called marrow. Red marrow is found in most bones of children, and is where red and white blood cells are made and mature. Yellow marrow is found in most adult bones, and is mostly composed of fat. The red marrow in childrens bones is slowly converted to yellow marrow as we age. In a middle-aged adult, usually only flat bones still contain red marrow.
While adult bone marrow does contain stem cells, they are limited in their ability to differentiate into other cell types compared to embryonic stem cells. Embryonic stem cells are pluripotent, meaning they can develop into any cell type in the body, making them more versatile for regenerative medicine and research. Additionally, obtaining embryonic stem cells does not require invasive procedures as collecting adult bone marrow does.

Yellow bone marrow mostly stores and is made up of fat cells. The yellow bone marrow makes up about half of the adult human bodies bone marrow.
