Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.
Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
Forams first appeared approximately 170 million years ago, and populate oceans globally. Forams are microscopic organisms, typically no larger than 1 mm in length. [25] The calcification and dissolution of their shells causes changes both in the surface seawater carbonate chemistry, and in deep-water chemistry. [25]
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
The osteoclast releases hydrogen ions through the action of carbonic anhydrase (H 2 O + CO 2 → HCO 3 − + H +) through the ruffled border into the resorptive cavity, acidifying and aiding dissolution of the mineralized bone matrix into Ca 2+, H 3 PO 4, H 2 CO 3, water and other substances. Dysfunction of the carbonic anhydrase has been ...
What happens to the bones? While flesh starts to decompose quickly, “bones will survive for decades,” points out Viddal. However, some do get broken down into smaller fragments during the ...
Bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and sizes and have a complex internal and external structure.
Calcium may come from one of two paths: through the gut where higher than normal levels of calcium are absorbed by the body or mobilized from stores in the bones. After initial 24 hour urine calcium testing and additional lab testing, a bone density scan (DSX) may be performed to determine if the calcium is being obtained from the bones.
