Compact Bone Anatomy

Small channels canaliculi radiate from the lacunae to the osteonic haversian. Together a canal and the osteocytes that surround it are called osteons.

Compact Bone Tissue Anatomy Physiology Bones Anatomy

Makes up the diaphysis of long bones and the external layer of all bones.

Compact bone anatomy. Most of the skeleton is composed of this. Compact bone is made of special cells called osteocytes. These cells are lined up in rings around the canals.

There are two types of bone tissue. 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. Osteon or haversian system.

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. Looks like solid hard layer of bone. Compact bone also known as cortical bone is a denser material used to create much of the hard structure of the skeleton.

As seen in the image below compact bone forms the cortex or hard outer shell of most bones in the body. Resists stresses produced by weight and movement. Morris velilla 52995 views.

Compact bone is the denser stronger of the two types of bone tissue. In this tutorial we are going to examining the microscopic features that make up our long bone anatomy. Between the rings of matrix the bone cells osteocytes are located in spaces called lacunae.

Long bone compact bone and spongy bone duration. Overall the bones of the body are an organ made up of bone tissue bone marrow blood vessels epithelium and nerves. 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.

Video number anatomy 1 41. Microscopic structures of compact bone wedge of bone duration. Compact bone is dense so that it can withstand compressive forces while spongy cancellous bone has open spaces and supports shifts in weight distribution.

Cortical bone is compact bone while cancellous bone is trabecular and spongy bone. The osteon consists of a central canal called the osteonic haversian canal which is surrounded by concentric rings lamellae of matrix. Compact bone makes up 80 percent of the human skeleton.

It can be found under the periosteum and in the diaphyses of long bones where it provides support and protection. Cortical and cancellous bone. Provides protection and support.

The remainder is cancellous bone.
