Detailed explanation-1: -Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae ) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Detailed explanation-2: -Compact bone is a robust and heavy bony structure that forms the diaphysis of long bones, whereas spongy bone is a soft and smooth bony structure that forms the epiphysis of long bones.
Detailed explanation-3: -If you look at compact bone tissue with naked eye, it look very dense: you cannot see any cavities in it. In contrast to compact bone tissue, spongy (cancellous) bone consists of an irregular latticework of thin blades of bone called trabeculae.
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.
Detailed explanation-5: -What structural differences did you note between compact bone and spongy bone? Compact bone has more bone matrix and less space due to osteons. Spongy bones have less bone matrix and more space due to trabeculae.
