Compact bone, H&E, unknown magn.
What type of tissue is this? What sturctures do the letters indicate?
- This is decalcified compact bone (yes, this is a review for
the final, but old stuff may appear there too). Note the shriveled osteocytes
(A) (preparation artifact that always occurs) in their lacunae (B).
Also, note the vessels in the middle and the lower right of the screen.
Those are Volkmann's canals (C) assuming that this was a cross section
(if it was longitudinal then this would be a Haversian canal; Haversian
canals run with the long axis of the bone, Volkmann's run perpendicular
to it). The presence of the vessels definitively shows that this cannot
be cartilage as cartilage is avascular.
