The dynamic nature of bone means that new tissue is constantly formed, and old, injured, or unnecessary bone is dissolved for repair or for calcium release. The cell responsible for bone resorption, or breakdown, is theosteoclast. They are found on bone surfaces, are multinucleated, and origin...
1.(Anatomy) any of the various structures that make up the skeleton in most vertebrates 2.(Anatomy) the porous rigid tissue of which these parts are made, consisting of a matrix of collagen and inorganic salts, esp calcium phosphate, interspersed with canals and small holes. ...
Bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. Bone tissue makes up the individual bones of the skeletons of vertebrates. Its two principle components are collagen and calcium phosphate. Learn more about
Bone tissue, or osseous tissue, is a type of connective tissue used in forming bones. Bones protect the vital organs and help support the body. It is composed mainly of collagen, or ossein, fibers, and bone cells called osteocytes. There are two types of bone tissue, referred to as ...
Bone tissue is a metabolically active organ undergoing continuous remodeling through the balanced activity of osteoclasts, the bone-resorbing cells, and osteoblasts, the bone-forming cells, both orchestrated by the osteocytes, the most abundant cells embedded into the bone matrix. Here, we will ...
Bones make good fossils. While the soft tissue of a once living organism will decay and fall away over time, bone tissue will, under the right conditions, undergo a process of mineralization, effectively turning the bone to stone. A well-preserved fossil skeleton can give us a good sense of...
Bone - Structure, Function, Types: Grossly, bone tissue is organized into a variety of shapes and configurations adapted to the function of each bone: broad, flat plates, such as the scapula, serve as anchors for large muscle masses, while hollow, thick-
Greene (1935) provided a diagram similar to Fig. 5.8. This shows the external pterygoid process sweeping back from the posterior corner of the maxilla to form a bar that passes below the foramen ovale (Rowett’s diagram, Fig. 5.8, agrees with this). The anatomy of the area just in ...
Anatomy and physiology of the blood supply to bone The channels and vessels in bone were observed by Van Leeuwenhoek and Havers in the late 17th century and were confirmed to be linked to blood supply by Albinus in the mid-18th century. The importance of the blood *Correspondence: Timothy R...
Sectional anatomy of the equine hoof wall. The dermis can be divided into 5 parts: perioplic, coronary, laminar, solar, and frog (Fig. 14.9-3). All but the laminar corium have papillae that extend into the epidermis. The laminar corium is the dermal tissue of the laminae and is a ...
