Spongy bone tissue/ Cancellous
Spongy bone consist web like arrangement of marrow filled spaces separated by thin bone is called trabeculae.
3. Trabecular
Spongy bone consist of interconnecting plates of bone is called trabeculae.
Trabeculae consist several lamellae.
Osteocytes located between the lamellae.
Osteocytes lie in lacunae.
Radiating from lacunae are canaliculi.
Space between trabeculae of some bone are filled with red bone marrow which produce blood cell.
Osteocytes in trabeculae receive nourishment directly from blood circulating through bone marrow.
Function
1. Responsible for production of red blood cell.
2. Provide greatest strength with least weight.
Cancellous bone consist of spongy, porous, bone tissue that is filled with red bone marrow.
Mostly concentrated in hip bone, skull, vertebrae, ribs, pelvis
Spongy bone is lighter than compact bone, reducing weight of skeleton.
