What are the functions of the spongy bone?
Spongy bone provides 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 bone marrow, protected by the trabeculae, where hematopoiesis occurs.
What is the function of the spongy bone quizlet?
What does spongy bone contain instead of capillaries and venules in its matrix? It fills spaces between the trabeculae, forms blood cells, supplies nutrients to osteocytes, and removes wastes.
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 advantage of spongy bone?
The advantages of Spongy bones is it’s lighter than compact bone yet still strong and they follow the lines of stress which helps with support. Which type of free movable joint allows for the most range of motion? Disks of rubbery cartilage are formed between the individual bones in the spinal column.
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.
Is spongy bone soft as sponge?
Though spongy bone may remind you of a kitchen sponge, this bone is quite solid and hard, and is not squishy at all. The inside of your bones are filled with a soft tissue called marrow. There are two types of bone marrow: red and yellow.
What is the difference structurally and functionally between compact and spongy bone?
Spongy and compact bones are two basic structural bone types….Spongy vs Compact Bones.
| Spongy Bones | Compact Bones |
|---|---|
| They are made up of trabeculae | They are made up of osteons |
| They fill the inner layer of most bones | They fill the outer layer of most bones |
| Bone-marrow cavity absent | Bone-marrow cavity present in the centre |
Which of the following is a characteristic of spongy bone?
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 name of the smallest functioning unit of spongy bone?
The functional unit of spongy bone is the trabecula.
How do spongy and compact bones differ in location and function?
What are two benefits of having a soft mostly hollow spongy part of our bones?
The lamellae of spongy bone form an open, porous network of bony branches, or beams, called trabiculae, that give the bone strength and make the bone lighter. This also allows room for blood vessels and bone marrow.
What are the functions of osteoclasts?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/ monocyte lineage that circulate in the blood after their formation in the bone marrow.
What are the advantages of spongy bone?
The light weight and low density of spongy bone balances out the heavier and denser compact bone to reduce the overall weight of the skeleton. This makes it easier for muscles to move the limbs . The trabeculae of spongy bone tend to form along lines of stress, giving the bone strength and flexibility in that area.
What is the importance of a spongy bone?
Spongy bone is also important for movement . If all of your bone tissue was compact, you’d probably be too heavy to move! Spongy bone also helps to absorb shock and stress from movement. There are a variety of different cells present in your bones.
What does the spongy part of the bone do?
Spongy bone is also called cancellous bone, which makes up a larger portion of the bone than the external compact bone tissue. Spongy bone often contains red bone marrow, the site of production of blood cells. The bone marrow fills up the open spaces between the trabeculae.
What does spongy bone have a lot of?
Spongy bone is home to the bone marrow and hematopoietic stem cells that differentiate into red blood cells, white blood cells and platelets. Compact bone, also called cortical bone, surrounds spongy bone and makes up the other 80\% of the bone in a human skeleton.
