Compact bone has no visible open spaces. Spongy bone, in contrast, has visible open spaces.
Cancellous bone, or spongy bone, has many open spaces and contains marrow. It is softer and weaker than compact bone.
Compact bone is the type of bone tissue without visible open spaces. In contrast, spongy bone has visible spaces.
Spongy bone
Spongy BoneA spongy bone is so spongy because, the spongy bone has many open spaces and contains bone marrow. But, spongy bone is know to be lightweight and very strong.It also contains trabeculae which allow for the "gaps" in the bone and allow it "give." It is also the only place where red marrow is found in adults.
Bone marrow, more specifically yellow bone marrow.
spongy bone has samall open spaces that make bones lightweight
The human bone structure is called a skeleton.
Spongy Bone has more surface area, but it is weaker and not as dense as compact bone. Compact Bone is the tough outer layer of bone while spongy bone is the porous bone where the red and yellow marrow is. Spongy is softer bone, with holes in it. It is found inside the bone. It is lighter than compact bone. Compact bone is generally on the outer edges of bone. it is composed of multiple osteon units that are bunched closely together like stacked logs and, thus, is good at bearing weight in the long direction. Spongy bone is generally on the inside of compact bone. Individual osteon-like struts (called trabeculae) branch in many directions and interconnect. Thus, there are spaces created where red marrow exists. This kind of bone is good at handling stress from multiple directions and is lighter weight. Spongy bone can appear yellow because it has some fat in it, and it is possible to see small holes in spongy bone. Compact bone is usually white. Also, spongy bone is not long (like the wrist) most irregular and flat bones are formed from spongy bone tissue. Compact bone is usually long (like a femur). Compact bone tissue is hard with few open spaces & provides protection and support.Spongy bone tissue is porous with many open spaces
Compact bone looks smooth and homogeneous. Spongy bone is composed of small needlelike pieces of bone and lots of open space.
what do you call something that has many open spaces
Bone is not a solid uniform material; it has spaces between the hard elements. The hard outer layer of the bone is made up of the compact cortical bone tissue that gives bone the hard, white, smooth solid appearance. This is often called 'dense' bone. The inside of the bone is filled with trabecular bone tissue (cancellous or spongy bone) which has a honeycombed appearance due to its open cell porous network made up of rod and plate elements that give the bone lightness and room for the blood vessels and bone marrow.
