Special form of collagen fibrils

Abstract

We found a special form of collagen fibrils in tentorium cerebelli and internal cranial periost of hen with two characteristics under electron-microscope:

1.	Collagen fibrils showing branching and anastomosing somewhat like the branching and anastomosing of heart muscle fibers.
2.	These branching collagen fibrils are at the same time shortperiodic with the cross-striated periods of 40–44 nm.

The possibility and significance of such special collagen fibrils have been discussed.

Keywords

branching and anastomosing collagen fibrils / shortperiodic collagen fibrils / dura mater encephali
