Sharpey’s Fibres
Sharpey's Fibres The periosteum is anchored to the outer part of bone tissue by Sharpey’s fibres. From the inner layer of the periosteum, coarse collagen fibres extend inwards to enter the bone matrix. These are called Sharpey’s fibres (perforating fibres). The Sharpey’s fibres enter the bone matrix like spikes of a shoe thus anchoring the periosteum to the … [Read more...] about Sharpey’s Fibres
