MEDULLARY SPACE Meaning and
Definition
-
Medullary space refers to the central cavity or canal found within the long bones of the body. It is commonly found in the diaphysis, the main shaft of a long bone. The medullary space is responsible for housing the bone marrow, which is essential for the production of blood cells, including red blood cells, white blood cells, and platelets.
The size and shape of the medullary space vary depending on the age of the individual. In infants and children, the medullary space is relatively large, containing yellow bone marrow composed mainly of fat cells. As an individual ages, the medullary space becomes narrower as more red bone marrow, responsible for hematopoiesis, is created. Hematopoiesis refers to the process of generating new blood cells, crucial for maintaining proper bodily functions.
The medullary space is lined by the endosteal membrane, which consists of connective tissue and cells. This thin membrane plays a vital role in the formation and remodeling of the bone tissue. Additionally, blood vessels and nerves can also be found within the medullary space, providing nutrients and sensory input to support bone health.
Overall, the medullary space serves as a crucial site for the production and maintenance of blood cells, as well as a conduit for blood vessels and nerves within the long bones of the body.
