Title: Bone: Sharpey’s fibres and tendon
Description:
Human bone, longitudinal section.
(A, B): Haematoxylin-eosin stained, the fibres of Sharpey are visualised.
(1): Bone.
(2): Sharpey’s fibres.
(3): Tendon.
(4): Fat cells (adipocytes).
(5) Dermis of the skin.
(B): Tangential section. Enlarged detail (2) of the inserted Sharpey fibres. (6): Bone matrix and osteocytes. (7): Collagen fibres and fibroblasts.
(C): Using polarisation microscopy the fibres of Sharpey are visualised.
Enlarged detail of the inserted or perforating Sharpey’s collagen fibres.
Sharpey’s “perforating” birefringent fibres provide anchorage for the periosteum as these collagen fibres penetrate into the outer lamellae of the bone layer. The collagen fibres from ligaments or tendons extend to the long axis of the bone at right angles or obliquely and continue in the collagen fibres of the ECM.
