Bone Tissue
Bone cells
Osteoblasts
-
-
-
Osteogenic cells
Osteogenic cells differentiate and develop into osteoblasts which, in turn, are responsible for forming new bones
-
Osteoclasts
-
Release acids which dissolve bony matrix.
Regulate calcium and phosphate concentrations in body fluids
-
Spongy Bone:
Collectively allow weight transfer, source of quick bone absoprtion and formation
Red marrow
Contains hematopoietic stem cells, which are the stem cells that form blood cells
-
the vertebrae, in the ribs, in the skull and in the bones of the joints.
Bone
Epiphyseal line
-
In adults, the epiphyseal plate is replaced with the epiphyseal line and marks the point of union were the epiphysis meets the diaphysis
Structure:
-
Diaphysis
The main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat)
Endosteum
A thin vascular membrane of connective tissue that lines the inner surface of the bony tissue that forms the medullary cavity of long bones.
Medullary Cavity
the area inside any bone (long, flat, etc.) that holds the bone marrow. This area is involved in the formation of red blood cells and white blood cells, and the calcium supply
Yellow marrow
contains mesenchymal stem cells (marrow stromal cells), which produce cartilage, fat and bone.
Periosteum
A membranous tissue that covers the surfaces of your bones. The only areas it doesn't cover are those surrounded by cartilage and where tendons and ligaments attach to bone
Appositional Growth
Occurs at endosteal and periosteal surfaces, increases width of growing bones
Compact Bone:
Osteons
-
-
-
Lamellae
-
Circumfernetial
Outer and inner rings of lamellae present deep to the periosteum and superficial to the spongy bone strength and tension resistance to the bone as a whole
Interstitial
transport nutrients to, and carry waste from, the bone cells (osteocytes) buried in the bony matrix.
-
Weight bearing, weight transfer, protection, site for muscle attachment
