Final answer:
The perforating canal is known as Volkmann's canal and differs from the Haversian canal; it extends blood vessels and nerves to the periosteum and endosteum.
Step-by-step explanation:
The perforating canal is also known as Volkmann's canal. These canals are channels that branch off from the central canal and house blood vessels, nerves, and lymphatic vessels that extend to the periosteum and endosteum.
Notably, the perforating canal is different from the Haversian canal, which runs longitudinally within the compact bone structure called the osteon or Haversian system.
Volkmann's canals are crucial for the vascularization and innervation of bone tissue. They help in the distribution of blood vessels and nerves throughout the bone, allowing for the exchange of nutrients, oxygen, and waste products between the bone cells (osteocytes) and the surrounding tissues.
These canals are named after German physiologist Alfred Volkmann, who extensively studied the anatomy of bones and their vascularization in the 19th century.
