Compact bone
The layers of calcified matrix in bone tissue are called lamellae. These lamellae are arranged in concentric circles around central canals called Haversian canals, forming the structure known as an osteon or Haversian system.
Bone cells surround Haversian canals. Osteon (Haversian system) is the structural unity of bone. Spaces for osteocytes are called lacunae. The matrix is present in concentric rings called lamellae. Canaliculi are canals that join lacunae with the central Haversian canal (central canal)
osteonic canals
Osteons (also called Haversian systems) form the basic structural unit of bone. Inside osteons we find the haversion canal - a central canal that contains the bone's nerve and blood supplies. The haversion canals surround these blood vessels and nerve cells. Communication with osteocytes in lacunae ("small lakes") through canaculi ("small canals") is possibly due to intercommunication channels between the haversion canals.
Compact bone tissue is arranged in concentric layers called lamellae around a central canal that contains blood vessels and nerves. These layers give compact bone its strength and resilience, helping to support the body and protect vital organs.
The use of concentric circles is most commonly used on a target. Concentric circles are placed around a target in which each concentric circle has the same center.

The matrix for bone is laid down in thin layers called 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. This pattern of concentric circles forms a cylinder-shaped unit called the osteon.
Concentric circles are circles that share the same center point, with each circle surrounding the other. Eccentric circles, on the other hand, do not share the same center point and are offset from each other. In simpler terms, concentric circles are like a target with multiple rings around a common center, while eccentric circles are like two circles that are not aligned at the same center point.
True. Bone cells, such as osteocytes, are indeed arranged in concentric circles around the Haversian canals in compact bone tissue to form structural units called osteons.
Osseous tissue has cells that are arranged in concentric circles around a nutrient canal matrix and is hard due to calcium salts.

osteonic canals
The concentric magnetic circles that run around a disk platter are called "tracks." Each track is a circular path on the surface of the disk where data is recorded. Data is organized in these tracks, and the read/write head of the disk accesses the information by moving to the appropriate track.
This theory was developed by the ancient Greek astronomer Claudius Ptolemy. Known as the Ptolemaic system, it held that planets move in circular orbits around the Earth. This geocentric model was widely accepted until the heliocentric model proposed by Copernicus in the 16th century.
