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. WebbFibres from the inner layer also penetrate the underlying bone, serving with the blood vessels to bind the periosteum to the bone as Sharpey fibres. The inner layer of the periosteum contains osteoblasts (bone-producing cells) and is most prominent in fetal life and early childhood, when bone formation is at its peak. how to show ppt

"WebbThe dominant collagen is type I, although small amounts of type III collagen may be present, particularly in immature or healing bone. Most of this collagen can be regarded as intrinsic collagen secreted by osteoblasts. However, collagen inserted as Sharpey’s fibers can be considered as extrinsic collagen formed by adjacent fibroblasts. " - Sharpey fibers definition collagen type

WebbThe periosteum overlaying the bone is a fibrous layer that consists largely of collagen fibers.
