They consist of two apposed 70 A membranes (arrows, inset) with a space (s, inset) about 200 A wide separating them. The lamellae are Interrupted in areas (a) by small vesicles and other vesicles occur at the periphery of the lamellae (b'). Concentric Lamellae Location. The Correct Answer is. Rings of bony matrix in each osteon. Reason Explained.

Concentric lamellae

The onion-like concentric structure produces the orientation-independent color, while few periods of the concentric photonic lamellae The lamellae are arranged in concentric patterns around tubes called osteonic canals. Between the layers of lamellae the osteocytes are placed in depressions called lacunae. It is soon replaced by lamellar bone, which is highly organized in concentric sheets with a much lower proportion of osteocytes to surrounding tissue. Lamellar bone, which makes its first appearance in humans in the fetus during the third trimester, [23] is stronger and filled with many collagen fibers parallel to other fibers in the same layer (these parallel columns are called osteons). Within a single trabecular, there are concentric lamellae, with osteocytes in lacunae connected to one another via canaliculi, similar to the tissue arrangement in the osteons of compact bone.

3. Interstitial lamellae are remnants of older osteons and circumferential lamellae found between newer, functional osteons. 4.

What is the concentric lamellae?

In cortical bone, the inner concentric lamellae of osteons were often unstained but the outer lamellae were heavily stained for osteocalcin.
