What are the thin plates in spongy bone quizlet?
Bone tissue that that consists of an irregular latticework of thin plates of bone called trabeculae; spaces between trabeculae of some bones are filled with red bone marrow; found inside short, flat, and irregular bones and in the epiphses (ends) of long bones.
How is spongy bone formed?
The non-mineralized portion of the bone or osteoid continues to form around blood vessels, forming spongy bone. Connective tissue in the matrix differentiates into red bone marrow in the fetus. The spongy bone is remodeled into a thin layer of compact bone on the surface of the spongy bone.
What are the thin plates or struts typically associated with spongy bone?
Trabeculae are thin plates or struts typically associated with spongy bone.
What area is made up of a thin layer of compact bone and a thick spongy bone?

What is the spongy bone called?
cancellous bone
cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called trabeculae, arranged along lines of stress.
What is the function of osteoblasts in the body?
Osteoblasts work in teams to build bone. They produce new bone called “osteoid” which is made of bone collagen and other protein. Then they control calcium and mineral deposition. They are found on the surface of the new bone.
Why is spongy bone so spongy?
Cancellous bone is called ‘spongy bone’ because it is very porous and resembles a sponge. It is spongy because of the presence of red bone marrow,…
Why are bones spongy?
Spongy bone reduces the density of bone and allows the ends of long bones to compress as the result of stresses applied to the bone. Spongy bone is prominent in areas of bones that are not heavily stressed or where stresses arrive from many directions.
What is the primary function of osteoblasts?
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.
What is the main difference between spongy bone and compact bone?
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 |
What is spongy bone called?

What is difference between compact bone and spongy bone?
Bones provide structural support and aid in the movement of the body parts. Compact and spongy bone are two types of bones found in the bone tissue. 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.
