Compact bone location and function

The compact bone is the main structure in the body for support protection and movement. Compact bones have high calcium content.

Spongy bone is used for more active functions of the bones including blood cell production and ion exchange.

Compact bone location and function. 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 strength. Spongy bone is used for more active functions of the bones including blood cell production and ion exchange.

However compact bones also serve a function in storing and releasing. Compact bone also called cortical bone is one of two types of bone connective tissue the other being spongy bone also called trabecular bone. Compact bone forms a protective shell around.

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. Compact bone makes up 80 percent of the human skeleton. The remainder is cancellous bone which has a spongelike appearance with numerous large spaces and is found in the marrow space.

Compact bones provide support to mammalian limbs. Moreover it is a storehouse of calcium and hosphorus. Compact bone is laid in such a manner that there are histological units seen in cross section.

Such roundish unit is called OSTEON. Each osteon has a central Haversian canal running parallel to long axis of bone. The function of compact bone is to help to keep the levels of these minerals at constant within the blood.

The arteries and veins that run through the Haversian canals provide a means to transport the minerals to and from the compact bone. Function of Compact Bone. 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 strength. Spongy bone is used for more active functions of the bones including blood cell production and ion exchange. Compact bone also called cortical bone is the hard stiff smooth thin white bone tissue that surrounds all bones in the human body.

It is also called osseous tissue or cortical bone and it provides structure and support for an organism as part of its skeleton in addition to being a location for the storage of minerals like calcium. 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 bone transitions to spongy bone. These are mostly compacted bone with little marrow and include most of the bones in the limbs. These bones tend to support weight and help movement.

These bones tend to. Several layers of bony matrix on the inside of the compact bone Inner Circumferential Lamellae Function Bind the osteons from the inside site of attachment for endosteum. Transverse canals of the compact bone enclosing blood vessels and nerves.

They connect the Haversian canals with each other and with the medullary cavity and the periosteum. Osteon Elementary cylindrical structure of the compact bone made up of four to 20 concentric. Compact bone is sometimes called cortical bone.

At the outer edges of compact bone rather than being arranged in osteons the osseous tissue is arranged in circumferential lamellae. These travel parallel to the outer edge of the bone and are usually only a few lamellae deep before the osteons start up. The bones of the body only have compact bone on their outermost surfaces and never very deep.

Compact bones are the present in the outer layer of long bones while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is. Most bones contain compact and spongy osseous tissue but their distribution and concentration vary based on the bones overall function.

Compact bone is dense so that it can withstand compressive forces while spongy cancellous bone has open spaces and supports shifts in weight distribution. Compact bones are located in all areas of the body as compact tissue forms the hard outer shell of bones. There are five main types of compact bones.

Long short flat irregular and sesamoid. These types of bones have their own function in the skeletal system depending on where they are located. Compact bone is the denser stronger of the two types of bone tissue.

It can be found under the periosteum and in the diaphyses of long bones where it provides support and protection. For healthy maintenance of the bone compact bones possess small passages for nerves and blood vessels. Compact bone consists of yellow bone marrow mainly for the storage of fat.

Moreover periosteum and endosteum cover the compact bone from outside and inner surface respectively. The endosteum is thin connective tissue. Also the marrow cavities of long bones are.

Compact bone consists of yellow bone marrow in the marrow cavity whereas spongy bones consist of red bone marrow in the spaces between lamellae. The yellow bone marrow stores fat while the red bone marrow produces red blood cells and granular white blood cells. Corticol bone also known as compact bone is dense and compact and found on the outside lining the bones.

Cancellous bone also known as spong bone is. Compact bone is hard and forms the outer layer of any bone. On the other hand spongy bone is softer and forms the inner layer of bones while covering a large surface area.

The main function of compact bone is to support the whole body whereas spongy bones support the body structure. Compact bones function is to provide structural support to the body. They function as a buffer system to the compact bone and support its function.

They are cylindrical shaped. They have a cuboidal structure. Compact bones have high calcium content.

They have low calcium content. They contain a yellow bone marrow in the bone marrow cavity. In the adult this occurs only in the bone marrow.

In the embryo this occurs in other locations yolk sac liver spleen thymus until bone develops. Haversian canal - the central canal of an osteon Haversian system in compact bone within which blood vessels and nerves travel throughout the bone.
