What is the function of spongy cancellous bone?
Cancellous bone (also known as spong bone) is spongy, soft and found within flat bones and at the ends of long bones. It contains the bone marrow, fat and blood vessels within it. The purpose of cancellous bone is to: House bone marrow (more red in children and turns yellow with age; can turn red again)
What is the cancellous bone?
Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).
What is the function of compact and spongy 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.
What is the difference between compact bone and cancellous bone?
Spongy and compact bones are two basic structural bone types. They make up the long bones in the body….Spongy vs Compact Bones.
Spongy Bones | Compact Bones |
---|---|
They fill the inner layer of most bones | They fill the outer layer of most bones |
Is cancellous bone soft?
It is also found inside the vertebrae, in the ribs, in the skull and in the bones of the joints. Spongy bone is softer and weaker than compact bone, but is also more flexible. It is characterized by a lattice-like matrix network called trabeculae (Latin for little beam) that gives it its spongy appearance.
What is the function of osteoblasts in the body?
Osteoblasts are specialized mesenchymal cells that synthesize bone matrix and coordinate the mineralization of the skeleton. These cells work in harmony with osteoclasts, which resorb bone, in a continuous cycle that occurs throughout life.
Why is it called cancellous bone?
Cancellous bone is also known as spongy bone because it resembles a sponge or honeycomb, with many open spaces connected by flat planes of bone known as trabeculae. Inside the trabeculae are three types of bone cells: osteoblasts, osteocytes and osteoclasts. Osteoblasts are the cells that make new bone.
What are spongy bones?
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
What is the function of lacunae?
Lacunae – Function The primary function of lacuna in bone or cartilage is to provide housing to the cells it contains and keeps the enclosed cells alive and functional. In bones, lacunae encase osteocytes; in cartilage, lacunae enclose chondrocytes.
What is the difference between bone and spongy bone?
There are blood vessels, nerves, and bone marrow within the lamella of both types of bones….What is the difference between Compact Bone and Spongy Bone?
Compact Bone Structure | Spongy Bone Structure |
---|---|
They are made of closely packed osteons. | They are composed of minerals containing trabeculae. |
What is the function of the Endosteum?
Endosteum consists of only a cellular layer, which contains bone lining cells, osteoblasts, and osteoprogenitor cells. Therefore, the main function of the endosteum is to help in the bone growth, repair, and remodelling.
What is the function of cells called osteoclasts?
OSTEOCLASTS are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells. They are formed from two or more cells that fuse together, so the osteoclasts usually have more than one nucleus. They are found on the surface of the bone mineral next to the dissolving bone.
What is the function of the cannon bone?
The cannon bone is a weight-bearing bone in the lower leg and stretches from the knee joint to the fetlock joint. On either side of the cannon bone are the splints that help support the carpus bones of the knee. Behind the fetlock joint are two bones known as the sesamoids.
What is the function of zygomatic bone?
The zygomatic bone is one of two bones (sometimes called malar bones) that are responsible for the prominences of the cheeks below and to the sides of the eyes. These bones also help form the lateral walls and floors of the orbits (eye).
What are the functions of the compact bone and spongy bone?
The main function of compact bone is to support the whole body , whereas spongy bones support the body structure. The latter helps save materials, and provide movement to the key body organs. Compact bones are heavy and tough as they store calcium in them, contributing to over 80\% of total human skeleton weight.
What is the function of cranial bones?
The cranial bones are a group of bones within the human head. These cranial bones form the structure of the top, back, and sides of the skull. The structure of the front of the head is formed by the facial bones. The functions of the cranium include holding in place and protecting the brain in its cavity, which is called the “cranial vault”.
