The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
The bone formation portion (σ f) of the bone remodeling period is calculated as follows: [5] = in which MWT refers to the mean wall thickness of the completed bone unit and M f refers to the prevailing mean effective bone appositional rate. In other words, what this formula means is that the bone remodeling period is equivalent to the ...
A set of mammal bones which may be from several specimens. In various archaeological disciplines including archaeology, forensic anthropology, bioarchaeology, osteoarchaeology and zooarchaeology, the number of identified specimens (also number of individual specimens or number of individual species), or NISP, is defined as the number of identified specimens for a specific site.
The canal of the nutrient foramen is directed away from more active end of bone when one end grows more than the other. When bone grows at same rate at both ends, the nutrient artery is perpendicular to the bone. Most other bones (e.g. vertebrae) also have primary ossification centers, and bone is laid down in a similar manner. Secondary centers
Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
The Haversian canals surround blood vessels and nerve cells throughout bones and communicate with osteocytes (contained in spaces within the dense bone matrix called lacunae) through connections called canaliculi. This unique arrangement is conducive to mineral salt deposits and storage which gives bone tissue its strength.
Add more bone-nourishing foods to your weekly menu. Foods like tofu, prunes, kale, yogurt, salmon and tahini are some of the best foods you should be eating more of for better bone health.
Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland. The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri , radii , and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes ...
