Vascular Spaces in Compact Bone: A Technique to Correct a Common Misinterpretation of Structure
Locke, M.; Dean, Rob L.
American Biology Teacher, v65 n9 p701-707 Nov-Dec 2003
Old bones are often discolored by the grime that infiltrates spaces in the matrix once occupied by blood vessels. This suggested that allowing dry bone to absorb colorants might be a useful way to show the three dimensional complexity of bone vascularization. The authors have developed a simple way to show blood vessels spaces in bone at a glance through a stereomicroscope. The procedure shows that the structure of bone described by artists in histology textbooks overlooks the sheets of capillary networks separating peripheral layers of laminar bone. It is surprising that this gross error has never been corrected, since even a cursory inspection of most long bones shows that capillary sheets are a dominant feature of bone architecture. In this article, the authors describe a simple technique to show students the three dimensional arrangement of spaces occupied by blood vessels in bone. The authors also correct a widespread misinterpretation of bone structure that they have found in all contemporary textbooks. (Contains 8 figures.)
