Compact Bone Anatomy

As seen in the image below compact bone forms the cortex or hard outer shell of most bones in the body. Osteons are like thick tubes all going the same direction inside the bone similar to a bundle of straws with blood vessels veins and nerves in the center.

Compact bone anatomy. Compact bone also known as cortical bone is a denser material used to create much of the hard structure of the skeleton. Osteon or haversian system. Cortical bone is compact bone while cancellous bone is trabecular and spongy bone.

These cells are lined up in rings around the canals. The osteon consists of a central canal called the osteonic haversian canal which is surrounded by concentric rings lamellae of matrix. The remainder is cancellous bone.

Small channels canaliculi radiate from the lacunae to the osteonic haversian. Microscopic structures of compact bone wedge of bone duration. Together a canal and the osteocytes that surround it are called osteons.

Between the rings of matrix the bone cells osteocytes are located in spaces called lacunae. Compact bone is made of special cells called osteocytes. Overall the bones of the body are an organ made up of bone tissue bone marrow blood vessels epithelium and nerves.

Compact bone is the denser stronger of the two types of bone tissue. Compact bone makes up 80 percent of the human skeleton. Resists stresses produced by weight and movement.

In this tutorial we are going to examining the microscopic features that make up our long bone anatomy. Compact bone is dense so that it can withstand compressive forces while spongy cancellous bone has open spaces and supports shifts in weight distribution. Makes up the diaphysis of long bones and the external layer of all bones.

Morris velilla 52995 views. Long bone compact bone and spongy bone duration. It can be found under the periosteum and in the diaphyses of long bones where it provides support and protection.

Cortical and cancellous bone. Compact bone also called cortical bone dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts leaving only tiny spaces lacunae that contain the osteocytes or bone cells. The basic structural and functional unit of compact bone opening in the center of an osteon carries blood vessels and layers of compact bone space containing osteocyte dimple looking things.

Most of the skeleton is composed of this. There are two types of bone tissue. Looks like solid hard layer of bone.

Provides protection and support.
