Compact bone and spongy bone

Osteoblasts bone lining cells osteocytes and osteoclasts 1 2. Their concentration and distribution can also be varied depending on the overall structure of bones.

Compact bones lack spaces between lamellae whereas spongy bones consist of spaces between lamellae.

Compact bone and spongy bone. 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. Compact bones are the hard exterior while spongy bones are the porous interior structures of bone tissue.

What is Compact Bone. The external cortical layers of all bone tissues are heavy hard and have a smooth surface. This layer of bone tissue is called compact bone.

A compact bone example would be the significant cortical bones of all long bones such as those on arms and legs. Compact bone also called cortical bone surrounds spongy bone and makes up the other 80 of the bone in a human skeleton. It is smooth hard and heavy compared to spongy bone and it is also white in appearance in contrast to spongy bone which has a pink color.

Compact bone appears solid and spongy bone consists of a web- or sponge-like arrangement of solidified extracelluar matrix. While compact bone appears at first glance to be solid and uninterrupted closer inspections reveals that the osseous tissue only makes up from 70-95 of the available volume. There are pores and spaces even in compact bone.

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.

The key difference between compact bone and spongy bone is that the compact bone is a tough and heavy bone that forms the diaphysis of long bones while the spongy bone is a soft and light bone that forms the epiphysis of long bones. Both are always together but the main difference between compact and spongy bone is that compact bone is the firmer outer layer of bone tissue which covers the internal surface while spongy bone is the softer more porous inner bone tissue which. 2-The differences between the compact and spongy bones.

The compact bone has strength in bending while spongy has strength in compression Cortical compact bone forms external layer of all bones and the most part of diaphysis body of the boneSpongy cancellous contains larger spaces and forms the majority of short flat and irregular bones. The main difference between compact and spongy aka cortical and cancellous bone is density. In compact bone the functional units of osteons are very compact and highly organized.

In spongy bone the opposite is true and the cells and bone material exist in a less compact matrix. The bones of animals can be spongy or compact osseous tissue. Their concentration and distribution can also be varied depending on the overall structure of bones.

The basic difference between Compact And Spongy Bones is that compact bones are those that are dense and can withstand compressive force while spongy are those bones that have open. The spaces of the trabeculated network provide balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. In addition the spaces in some spongy bones contain red marrow protected by the trabeculae where hematopoiesis occurs.

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 cellsCompact 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. 1 Compact bone.

They are tough and heavy bones made of compactly packed osteons. They form the shaft or diaphysis of long bones. They form the shaft or diaphysis of long bones.

They are soft and light bones make up of loosely packed trabeculae. Both compact bone and spongy bones are structural bones. Both provide shape and structure to the organism.

Both are osseous tissues. What type of tissue is bone. Bone is a mineralized connective tissue that exhibits four types of cells.

Osteoblasts bone lining cells osteocytes and osteoclasts 1 2. Bone exerts important functions in the. The main difference between compact and spongy bone is that compact bone is the hard outer layers of the bone whereas spongy is the more porous inner layers of the bone.

Compact bones lack spaces between lamellae whereas spongy bones consist of spaces between lamellae. The main difference between spongy and compact bone is that compact bone is very dense and heavy while spongy bone is very porous. Figure 633 Anatomy of a Flat Bone.

This cross-section of a flat bone shows the spongy bone diploë covered on either side by a layer of compact bone. Bone Matrix and Cells Bone Matrix Osseous tissue is a connective tissue and like all connective tissues contains relatively few cells and large amounts of extracellular matrix. Compact bone tissue consists of osteons that are aligned parallel to the long axis of the bone and the Haversian canal that contains the bones blood vessels and nerve fibers.

The inner layer of bones consists of spongy bone tissue. The small dark ovals in the osteon represent the living osteocytes. Modification of work by NCI NIH.

Compact bone is what is found on the outside of most bones. It is the hard outer layer that gives bones their smooth white appearance. This type of bone has a much greater mass than the same amount of spongy bone which is found in places such as joints and the ends of bones.

Start studying compact and spongy bone. Learn vocabulary terms and more with flashcards games and other study tools. Compact bone makes up roughly 80 of the total weight of bones in the human body while spongy bone also known as cancellous bone makes up.

A long bone is organized into periosteum which includes an outer fibrous and inner cellular layer that contains osteoblasts compact bone spongy bone and bone marrowArticular hyaline. Start studying anatomy compact and spongy bone structure. Learn vocabulary terms and more with flashcards games and other study tools.

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 calcium to the body when needed.
