Medullary cavity: Anatomy, structure and function | Kenhub
Oct 30, 2023 · The medullary cavity (marrow cavity) is the hollow central space found within the shaft (diaphysis) of long bones. Its walls are formed by a thin layer of spongy bone, which is itself surrounded by a thick layer of compact bone comprising the diaphysis.
Medullary cavity - Wikipedia
The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.
Medullary cavity - Structure, Appearance, Location, Function
Dec 21, 2022 · Medullary cavity, also known as the marrow cavity or the medulla, is a hollow space located within the long bones of the body, such as the humerus, femur, and tibia. It is filled with a soft, spongy tissue called bone marrow, which plays a vital role in the production of red and white blood cells.

Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult. The outer walls of the diaphysis ( cortex, cortical bone) are composed of dense and hard compact bone, a form of osseous tissue.
7.5: Anatomy of a Long Bone - Biology LibreTexts
A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.
5.3: Bone Structure - Medicine LibreTexts
Sep 25, 2024 · A hollow medullary cavity filled with yellow marrow runs the length of the diaphysis of a long bone. The walls of the diaphysis are compact bone. The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow.
6.3 Bone Structure - Anatomy and Physiology 2e - OpenStax
The medullary cavity has a delicate membranous lining called the endosteum (end- = “inside”; oste- = “bone”), where bone growth, repair, and remodeling occur. The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri - = “around” or “surrounding”).

Jul 27, 2024 · The medullary cavity of long bones, especially in children and adolescents, contains red bone marrow, which is the site of hematopoiesis. This process produces red blood cells, white blood cells, and platelets, essential for oxygen transport, immune defense, and blood clotting, respectively.
