structure of bone

This spongy mesh–like bone is designed for strength similar to steel rods within a concrete structure. The inner bone cavities contain bone marrow where red blood cells are produced. Cancellous bone (also called trabecular bone) is an inner spongy structure that resembles honeycomb, which accounts for 20% of bone mass.

Bone Structure. Compact bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces that contain the osteocytes, or bone cells. The shape of bone is described as long, short, flat, or irregular. Structure of Bone Tissue.

Compact bone, also known as cortical bone, is a denser material used to create much of the hard structure of the skeleton. Bone marrow is the soft, flexible connective tissue within bone cavities. Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it.

Bone having a unique feature of regeneration capacity as well undergoes continual structural remodeling through a cycle of resorption and renewal. The structure of a long bone allows for the best visualization of all of the parts of a bone . Matrix.

(From Muscolino JE: Kinesiology: the skeletal system and muscle function, St Louis, 2006, Mosby, Figure 3-2.) Anatomy of a Long Bone A typical long bone shows the gross anatomical characteristics of bone. There are two kinds of bone tissue (see Figure 1): Compact bone is the hard material that makes up the shaft of long bones and the outside surfaces of other bones. Figure 2-3 The primary components of a bone.

It accounts for about 80 percent of the total bone mass of the adult skeleton. Figure 6.3.3 – Anatomy of a Flat Bone: This cross-section of a flat bone shows the spongy bone (diploë) covered on either side by a layer of compact bone. Bone structure Your bones contain blood vessels, nerve cells and living bone cells known as osteocytes. The bone defect repairing technique and BTE required a comprehensive knowledge about bone mechanics, bone structure, and tissue formation for the design of new functional bones. Functions of the skeleton. The diaphysis is the central shaft of the bone. Cancellous bone (also called trabecular bone) is an inner spongy structure that resembles honeycomb, which accounts for 20% of bone mass.

A long bone has two parts: the diaphysis and the epiphysis. Compact bone consists of cylindrical units called osteons. The outside cortical bone is solid bone with only a few small canals. It makes up the majority of the bone and is formed by calcium phosphate crystals deposited as hydroxyapatite. Bone, the material that makes vertebrates distinct from other animals, has evolved over several hundred million years to become a remarkable tissue. Cortical bone tissue gives bone its smooth, dense, solid appearance. Most bones have common structural features important for maintaining their health and integrity. Compact bones make up 80 percent of the human skeleton; the remainder is spongelike cancellous bone. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone.

The bone matrix is made up compact, cancellous and subchondral tissue. This spongy mesh–like bone is designed for strength similar to steel rods within a concrete structure.

As its name suggests, spongy bone is porous like …

Spongy bone tissue fills part or all of the interior of many bones. Structure of the Bone. The insides of the bone contain trabecular bone which is like scaffolding or a honey-comb. Figure 6.3.6 – Diagram of Compact Bone: (a) This cross-sectional view of compact bone shows several osteons, the basic structural unit of compact bone. The spaces between the bone are filled with fluid bone marrow cells, which make the blood, and some fat cells. Spongy bone, also known as cancellous bone or trabecular bone, is a very porous type of bone. Mineral. There are two types of bone tissue: compact and spongy.The names imply that the two types differ in density, or how tightly the tissue is packed together. Proteins from bone extracellular matrix are known to mediate the organization of apatite crystals in bone.
