Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the haversian canal. The haversian canal contains the bone's blood supplies. Near the surface of the compact bone, the lamellae are arranged parallel to …

-The concentric lamellae are circular plates of the mineralized extracellular matrix of increasing diameter or surrounds a network of blood vessels and nerves located in the central canal. -These tube-like units form parallel cylinders that, runs parallel to the long axis of the bone.

Interruptions, which occur in the myelin sheath at regular intervals along the length of axons and expose the axon, are called nodes of Ranvier ( Figure 6 ).

Initially, the number of concentric lamellae of rER surrounding a lipid droplet may vary from less than a dozen to more than two dozen. During middle and late phases of vitellogenesis, most of the lipid spheres that comprise the most numerous and significant component of the yolk are surrounded by only one or two concentric lamellae of rER (in some cases the lamellae are part rough-surfaced

Progressive addition of lamellae leads to the formation of the systems of concentric lamellae. (ii) After digestion of the bacteria has proceeded to a high degree, the concentric lamellae are formed spontaneously from clouds of amorphous material through condensation and orientation of precursor material.

6-7 Collagen fiber 2. The outer surface of compact bone consists of circumferential The lamellae are the concentric circles around the Haversian canal; they are a bone matrix formed from calcium, phosphorus salts and fibres. The lacunae are small spaces in the lamellae which provide an area for bone cells or osteocytes. This is the key difference between lamellae and lacunae.
