Document Summary
Bone tissue continuously growing, remodeling, and repairing. Provides homeostasis with support and protection, producing blood cells, storing minerals and triglycerides. Bone made of osseous tissue, cartilage, dense connective tissues, epithelium, adipose tissue, and nervous sittue. Contains extracellular matrix of 15% water, 30% collagen fibers, 55% crystallized mineral salts. Different salts crystallize (calcification), initiated by osteoblasts (bone- building cells) Combination of crystalized salts and collagen fibers gives bone its characteristics. Bone"s hardness depends on crystallized inorganic mineral salts, flexibility depends on collage fibers. Osteoblasts build bone, osteoclasts carve out bone. Contains few spaces, strongest form of bone tissue. Under periosteum of all bones, makes up bulk of diaphyses of long bones. Provides protection and support and resists stresses produced by weight and movement. Spongy bone tissue located in interior of bone, protected by covering of compact bone. Consists of lamellae arranged in irregular pattern of thin columns (trabeculae)
