Transverse Section of Tibia Bone
The left tibia cross-section at 50 % biomechanical length [A] with the detail of cortical bone [B]. The periosteal (1) and endosteal (2) digitalized margins are distinguished by black lines. The artefacts (3, 4) are pointed out in the detailed picture
Medullary Cavity
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.
