APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Compact bone also called cortical bone, is dense in texture like ivory, but is extremely porous, because it contains many tiny passages for blood vessels and nerves and houses the cell, that repair and maintain bones. Cortical bone makes up 80% of the human skeleton, the remainder is cancellous bone.

Detailed explanation-2: -In compact bone, the haversian systems are packed tightly together to form what appears to be a solid mass. The osteonic canals contain blood vessels that are parallel to the long axis of the bone.

Detailed explanation-3: -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.

Detailed explanation-4: -compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.
