Webb1 dec. 2024 · Collagen is a form of loose connective tissue. This type of tissue includes fibers, ground substance, basement membranes and a variety of free-existing (e.g., circulating in blood) connective tissue cells. In addition to collagen fibers, the fiber type of loose connective tissue includes reticular fibers and elastic fibers. Webb21 feb. 2024 · eLife 11 :e77041. When our bodies heal following an injury, fibroblasts and other cells deposit components of the extracellular matrix, such as collagen, that form a ‘scar’ over the damaged area. This process, known as fibrosis, leads to a build-up of stiff fibrotic tissue that interferes with the activity of the underlying organ.

WebbThe ends of the principal fibers that are within either cementum or alveolar bone proper are considered Sharpey fibers. Transseptal fibers The transseptal fibers extend interproximally just over the alveolar bone crest. They are embedded into the cementum of the adjacent teeth where they form an interdental ligament. WebbThe periosteum overlaying the bone is a fibrous layer that consists largely of collagen fibers. This periosteum is mounted to the bone by Sharpey fibers, that are collagenous bundles trapped within the calcified bone matrix throughout ossification. The bone matrix is produced by osteoblasts derived from the less differentiated osteogenic cells.
