GENERAL HISTOLOGY

Detailed explanation-1: -In compact bone, blood vessels are found in Volkmann’s canals, central canals, the periosteum and the marrow cavity. The canaliculi in compact bone do not contain any blood vessels, but rather contain the cytoplasmic processes of osteocytes, the cells that reside in the lacunae of compact bone.

Detailed explanation-2: -In compact bone, the haversian systems are packed tightly together to form what appears to be a solid mass. The osteonic canals contain blood vessels that are parallel to the long axis of the bone. These blood vessels interconnect, by way of perforating canals, with vessels on the surface of the bone.

Detailed explanation-3: -Compact Bone Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels.

Detailed explanation-4: -Each central canal runs parallel to the long axis of the bone. It’s where blood vessels, lymph vessels, and nerves are located. It also contains a small amount of connective tissue. Perforating canals, also known as Volkmann’s canals, run at right angles to central canals.

Detailed explanation-5: -Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.
