Question

The medullary cavity is the site for blood cell formation in the adult skeleton.

The medullary cavity in adult bones is primarily a storage site for yellow bone marrow (adipose tissue). Blood cell formation (hematopoiesis) occurs primarily in the red bone marrow of certain bones, such as the sternum, ribs, and pelvic girdle.
