Question

Where does harvesian canal is present

Answer 1

Harvesian canals are a series of microscopic tubes in the outermost region of bone called corticalthat bone that allow blood vessels and nerves to travel through them.
The haversian canals surround blood vessels and nerve cells throughout bones and communicate with bone cells (contained in spaces within the dense bone matrix called lacuane) through connections called canaliculi. This unique arrangement is conducive to mineral salt deposits and storage which gives bone tissue its strength.
