That is 'aversion'.
haversian system
Another name for Haversian system is osteon.
Haversian Canals
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.
Haversian canals branch into the compact bone, they caring blood vesels which nourish the osteocytes.
osteonic canals
The central, or Haversian, canal. The canal runs through the core of each osteon.
There is no such thing as a haversian valve. It is likely a confusion or a misunderstanding. The Haversian system, also known as an osteon, is a structural unit of compact bone tissue in the body. It consists of concentric layers of mineralized bone tissue surrounding a central canal that contains blood vessels and nerves.
The haversian canals are used to transport oxygen to the bone cells. It also contains the nerves for the bones.
The Haversian canal is typically oriented vertically within the compact bone, running parallel to the long axis of the bone. These canals are part of the osteon or Haversian system, which is the structural unit of compact bone. They contain blood vessels, nerves, and lymphatic vessels that supply the bone tissue. Thus, the Haversian canal is not horizontal; rather, it is primarily vertical.
The haversian canal is the axis of the basic unit of bone, the osteon, and it has longitudinal orientation. The Volkmann`s canal has a transverse orientation and interconnect different Haversian canal between them.
No. That is a picture of the Martian surface and Haversian canals are found in animal bones on Earth.
