Structure of a compact bone

Four types of cells compose bony tissue. Compact bone forms the outer shell of bone.

The compact bone is the main structure in the body for support protection and movement.

Structure of a compact bone. Compact Bone Structure The basic units of compact bone are called osteons or Haversian systems. These are cylinder-shaped structures that have a mineral matrix and are home to osteocytes mature bone cells that are trapped in the matrix. Usually found in long bones of the body it consists of units called osteons each of which is called a haversian system with a series of canals concentric rings and bone cells called osteocytes.

The structure of compact bone is typically dense. It protects the inner sections as well as helps long bones tolerate the weight of the body and stresses during physical activity. Compact bone as opposed to spongy bone is made of cylindrical units called osteons that are tightly formed together.

As compact bone grows osteons begin to fuse together. Some of the features of compact bone include osteoblasts bone cells that produce new bone tissue osteons functional unit of compact bone lamellae layers of tissue that form concentric. 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. The remainder of the bone is formed by cancellous or spongy bone. Compact bone is made of concentric layers of osteocytes and bony matrix.

Compact bones provide support to mammalian limbs. Moreover it is a storehouse of calcium and hosphorus. Mature compact bone is lamellar or layered in structure.

It is permeated by an elaborate system of interconnecting vascular canals the haversian systems which contain the blood supply for the osteocytes. The bone is arranged in concentric layers around those. The compact bone is the main structure in the body for support protection and movement.

Due to the strong nature of compact bone compared to spongy bone it is the preferred tissue for strengthSpongy bone is used for more active functions of the. Compact bone is the denser stronger of the two types of osseous tissue Figure 636. It makes up the outer cortex of all bones and is in immediate contact with the periosteum.

In long bones as you move from the outer cortical compact bone to the inner medullary cavity the. Compact bone or cortical bone forms the hard external layer of all bones and surrounds the medullary cavity or bone marrow. It provides protection and strength to bones.

Compact bone tissue consists of units called osteons or Haversian systems. Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic haversian canal which is surrounded by concentric rings lamellae of matrix.

Between the rings of matrix the bone. Also Haversian system basic structural unit of compact bone. Made of concentric layers of calcified matrix perforating canal also Volkmanns canal channel that branches off from the central canal and houses vessels and nerves that extend to the periosteum and endosteum.

The microscopic structural unit of compact bone is called an osteon or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae singular lamella. Compact bone tissue is composed of osteons and forms the external layer of all bones.

Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Four types of cells compose bony tissue. Osteocytes osteoclasts osteoprogenitor cells and osteoblasts.

Microscopic structure of compact bone. The walls of the diaphysis are composed of dense and hard compact bone. Inside the caniculi extensions or arms of the osteocytes travel to touch the osteocyte next to them.

Compact bone forms the outer shell of bone. In this type of bone the lamellae are organised into concentric circles which surround a vertical Haversian canal which transmits small neurovascular and lymphatic vessels. The structure of a compact bone is shown in figure 1.

The osseous tissue of a compact bone consists of osteocytes surrounded by a solid extracellular matrix. The mineral that is found in the extracellular matrix of bones is hydroxyapatite. Hydroxyapatite is rich in calcium and phosphorous.

Compact bone histology From the compact bone histology slide I will enlist some important histological features that you might identify at the laboratoryFirst you should find out these features or structures from the bone slide pictures. Internal circumferential lamellae of compact bone. This is an online quiz called Structure of compact and spongy bone.

There is a printable worksheet available for download here so you can take the quiz with pen and paper. Your Skills Rank. Bone marrow stores fat.

It forms the ends or epiphyses of long bones. It forms the shaft or diaphysis of long bones. Compact bones are the present in the outer layer of long bones while spongy bones are present in the middle of the long bones.

Throughout compact bone oriented parallel to the long axis of the bone or in the direction of applied force. Central channel for vessels and nerves. Conduct vessels and nerves throughout the length of the osteon.
