What type of growth occurs in bone?
In endochondral ossification, bone develops by replacing hyaline cartilage. Activity in the epiphyseal plate enables bones to grow in length (this is interstitial growth). Appositional growth allows bones to grow in diameter. Remodeling occurs as bone is resorbed and replaced by new bone.
What is longitudinal bone growth?
Longitudinal bone growth is the result of chondrocyte proliferation and subsequent endochondral ossification in the epiphyseal growth-plates. The growth-plate is a cartilaginous template that is located between the epiphysis and the metaphysis of the long bones.
What is interstitial growth?
In this framework, interstitial growth represents the addition (or removal) of mass from the porous solid matrix of a mixture whose interstitial fluid provides the building blocks (or nutrients) for growth in the form of solutes mixed in a solvent.
Where is interstitial growth?
Interstitial growth is the lengthening of the bone resulting from the growth of cartilage and its replacement with bone tissue. A person grows taller because of interstitial growth. This growth occurs at the epiphyseal plate and continues until the person reaches the teenage years.
What is epiphyseal growth?
The epiphyseal growth plate is the main site of longitudinal growth of the long bones. At this site, cartilage is formed by the proliferation and hypertrophy of cells and synthesis of the typical extracellular matrix. The formed cartilage is then calcified, degraded, and replaced by osseous tissue.
What is needed for good bone growth?
Calcium, magnesium and phosphorus are the major minerals needed to encourage strong, healthy bones. Dairy products, such as milk, yogurt and cheese, contain all three of these minerals. You also get dietary calcium from eating broccoli, dark green leafy vegetables, tofu and dried beans.
How can you promote bone growth?
Foods With Major Minerals. Calcium,magnesium and phosphorus are the major minerals needed to encourage strong,healthy bones.
What does normal bone growth depend on?
Normal bone growth depends on the production of cartilage (a fibrous connective tissue). Over time, calcium is deposited within the cartilage, causing it to harden and become bone.
What substances contribute to bone growth?
Osteoinductivity describes the property of graft material in which it induces de novo bone growth with biomimetic substances, such as bone morphogenetic proteins. Such materials will contribute to new bone growth in an area where there is no vital bone, such as when implanted into muscle tissue.
