where do you find red marrow in adu?
(peripheral) appendicular skeleton
the composition of marrow is dynamic, as the mixture of cellular and non-cellular components (connective tissue) shifts with age and in response to systemic factors. in humans, marrow is colloquially characterized as "red" or "yellow" marrow (, , respectively) depending on the prevalence of hematopoetic cells vs fat cells. while the precise mechanisms underlying marrow regulation are not understood, compositional changes occur according to stereotypical patterns. for example, a newborn baby's bones exclusively contain hematopoietically active "red" marrow, and there is a progressive conversion towards "yellow" marrow with age. in adults, red marrow is found mainly in the central skeleton, such as the pelvis, sternum, cranium, ribs, vertebrae and scapulae, and variably found in the proximal epiphyseal ends of long bones such as the femur and humerus. in circumstances of chronic hypoxia, the body can convert yellow marrow back to red marrow to increase blood cell production.
bone marrow
bone marrow, also known as myeloid tissue in red bone marrow, can be found in almost any bone that holds cancellous tissue. in newborns, all such bones are filled exclusively with red marrow or hematopoietic marrow, but as the child ages the hematopoietic fraction decreases in quantity and the fatty/ yellow fraction called marrow adipose tissue (mat) increases in quantity. in adults, red marrow is mostly found in the bone marrow of the femur, the ribs, the vertebrae and pelvic bones.
