Cancellous tissue has spaces inside it, like a honeycomb. Compact tissue is solid and dense with no visible spaces.
Spongy inner layer called cancellous bone. Spongy bone is lighter and less dense than compact bone
There are two types of tissue that make up bones: Compact and Spongy
The part of bone you are asking about is called compact bone, or cortical bone.
Bones are composed of two tissue types. Compact, or dense bone, and spongy, or cancellous, bone. Most bones contain both types. Compact bone is dense, hard, and forms the protective exterior portion of all bones. Spongy bone is inside the compact bone and is very porous (full of tiny holes). Spongy bone occurs in most bones. The bone tissue is composed of several types ofbone cells embedded in a web of inorganic salts (mostly calcium and phosphorus) to give the bone strength, and collagenous fibers and ground substance to give the bone flexibility.
Cancellous bone, synonymous with trabecular boneor spongy bone, is one of two types of osseous tissue that form bones. Compared to compact bone, which is the other type of osseous tissue, it has a higher surface area but is less dense, softer, weaker, and less stiff. It typically occurs at the ends of long bones, proximal to joints and within the interior of vertebrae. Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis, the production of blood cells, occurs. The primary anatomical and functional unit of cancellous bone is the trabecula
Maybe a little, but most red bone marrow is foundin the SPONGY bone of the skull,ribs,sternum, vertebrae and in the end of long bones.
Although compact bone looks hard and solid, a microscope reveals that it is riddled with passageways that serve as conduits for nerves, blood vessels, and lymphatic vessels. Spongy bone looks like a poorly organized tissue. Spongy bone looks like Swiss cheese with the many holes presented.
The type of bone tissue that gives a bone its strength is called cortical or compact bone tissue. This type of bone tissue is dense and forms the outer layer of most bones in the body, providing strength, support, and protection. Cortical bone tissue contains mineralized collagen fibers that are arranged in a parallel fashion, giving the bone its characteristic strength and resistance to bending or breaking.
Red marrow is found in long bones, also associated with them are tendons and ligaments (connective tissues and hylaine cartilage. The bone itself is made of cancellous tissue.
