An osteon is a long cylindrical tube shaped unit in mature compact bone. It consists of concentric layers of bone lamellae surrounding a central canal also known as the Haversian system. They are oriented parallel to the long axis of the bone and to the main compression stresses. Structurally a group of concentric tubes resembling rings of a tree trunk. Each tube is a lamellae( little plate); a layer of bone matrix which collagen fibers and mineral crystals line up and run in opposite direction. This pattern alternates to withstand torsion, twisting and stresses and inhibits crack propagation.
Through the core of the osteon runs the Haversian canal also known as central canal and like all bone cavities it is lined with endosteum. It has its own blood vessels that supply nutrients to the bone cells of the osteon and its own fibers.

What do haversian canals contain?
They are part of the microscopic structure of compact bone. Compact bone is solid, dense, and smooth.The structural unit of compact bone is the Haversian system or Osteon. These are elongated cylinders cemented together to form the long axis of a bone.Components of Haversian system consists of osteocytes (spider-shaped bone cells that lie in "lacunae") that have laid down a matrix of collagen and calcium salts in concentric lamellae (layers) around a central Haversian canal containing blood vessels and nerves.Each system has communicating canals within compact bone with other systems.
What are fingers and toes composed of?
Fingers and toes are no doubt composed of cells and tissues.
Is diamond composed of a single element?
Diamond is composed of carbon -- a single element. Quartz is the second most abundant mineral on earth.Quartz is formed from silicone, in fact silicon-oxygen tetrahedra. Quartz then, is composed of two elements.
What is social race?
Its an achieved status with a racial label in a system of stratification that is composed of open, class-like categories to which racial labels are assigned. So basically, status labels in hierarchal societies where racial labels are determinant of said status labels.

Another word for osteon is?
haversian system
What is another name for haversian system?
Another name for Haversian system is osteon.
Are osteon and haversian system synonymous?
Yes, osteon and Haversian system are synonymous terms. The Haversian system is a structural unit of compact bone tissue, and it consists of concentric rings of bone matrix called lamellae surrounding a central canal known as the Haversian canal. Each Haversian system is also referred to as an osteon.
What is the functional unit of bone?
The functional unit of bone is the osteon, also known as the Haversian system. It consists of concentric layers of bone tissue surrounding a central canal that contains blood vessels and nerves. Osteons are responsible for the strength and integrity of bones.
The canal that runs through the core of each osteon (Haversian system) contains?
Blood vessels and nerves that supply nutrients to the bone cells within the osteon (Haversian system).
What are the structures that comprise a Haverson canal system?
Compact bone consists of a repeating structure called a Haversian system, or osteon, which is the primary anatomical and functional unit. Each osteon has concentric layers which are deposited around a central canal, also known as the Haversian canal, each containing a blood and nerve supply.
What is the functional unit of compact bone?
The basic unit of a compact bone is an osteon. This is also known as the Haversian canal and it contains blood vessels that transport blood to the bone.
What is the structure of osteon?
An osteon is composed of concentric rings of bone matrix called lamellae surrounding a central canal called the Haversian canal. Within the Haversian canal run blood vessels and nerves that supply nutrients to bone cells. Osteocytes, the bone cells, are located in spaces called lacunae between the lamellae.
What is the tube called in the center of an osteon?
The central canal in the center of an osteon is called the Haversian canal. It contains blood vessels and nerve fibers that supply the osteocytes within the osteon.
What is the channel extending through a osteon?
The channel extending through an osteon is called a Haversian canal. It contains blood vessels, nerves, and lymphatics that supply the bone cells within the osteon with nutrients and oxygen while also allowing for waste removal.
What is the canal that runs through each of the core osteon or haversian canals?
The canal that runs through each core osteon or Haversian canal is called the Haversian canal or central canal. It contains blood vessels, nerves, and lymphatics that supply nutrients and oxygen to the bone cells within the osteon.
What is the basic unit of bone tissue?
The basic unit of bone tissue is the osteon, also known as the Haversian system. This structure consists of concentric layers of bone tissue surrounding a central canal that contains blood vessels and nerves. Osteons are responsible for the strength and support of bones.
