Medullary Cavity
-
Tissue that produces blood cells
Red bone marrow
-
Membrane covering the outside of all bones
Periosteum
-
Spongy bone found in the ephiphysis and contains bone cells
Cancellous Bone
-
Bone builders, form a bone matrix that becomes enclosed as an osterocyte
Osteoblasts
-
Mature bone cells within the compact bone matrix. Maintain bone as living tissue and sustain daily bone.
Osteocytes
-
Large multinucleate cells that break down bone and play a role in mineral homeostasis
Osteoclasts
-
White fibrous connective tissue, cartilage, and bone
Collagen
-
Consists of Calcium and phosphate, weight-bearing strength
Hydroxyapatite
-
Necessary for collagen synthesis by the osteoblasts
Vitamin C
-
Necessary for the normal absorption of calcium from the intestines
Vitamin D
-
Junction between 2 or more bones where bones are connected together, aka articulations
Joint
-
Connective membrane that lines joints and produces a clear lubricating liquid
Synovium
-
A closed sac containing synovial fluid
