GENERAL HISTOLOGY

Detailed explanation-1: -The Haversian canals surround blood vessels and nerve cells throughout bones and communicate with osteocytes (contained in spaces within the dense bone matrix called lacunae) through connections called canaliculi.

Detailed explanation-2: -A central Haversian canal penetrates the osteon and serves as a passage for blood cells, lymph vessels, and nerves.

Detailed explanation-3: -The Haversian canals surround blood vessels and nerve fibers throughout the bone and communicate with osteocytes. The canals and the surrounding lamellae are called a Haversian system (or an osteon). A Haversian canal generally contains one or two capillaries and nerve fibers.

Detailed explanation-4: -Volkmann’s canals are channels that assist with blood and nerve supply from the periosteum to the Haversian canal. One or two main diaphyseal nutrient arteries enter the shaft obliquely through one or two nutrient foramina leading to nutrient canals.
