What Is Spongy Bone

The spaces between are often. It is highly vascularized and contains red bone marrow.

What is spongy bone. Cancellous bone also called trabecular or spongy bone is the internal tissue of the skeletal bone and is an open cell porous network. Cancellous bone light porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance. Encased within these layers is the tissue that makes up most of the volume of bone called cancellous or spongy bone because it contains little hollows like those of a sponge.

Spongy bone is light and porous and found in most parts of the body and in other bones that do not typically endure large volumes of mechanical stress. In addition to long bones the four other types of bones in the human skeleton are short bones the tarsal bones of the wrists and feet flat bones skull rib cage sternum scapula sesamoid bones knee cap and irregular bones. The bone matrix or framework is organized into a three dimensional latticework of bony processes called trabeculae arranged along lines of stress.

Spongy bone is lighter softer and weaker than compact or cortical bone the other type of calcium tissue but it has a greater surface area and is much more vascular or supplied with blood vessels spongy bone is found on the inside of some bones and it is. While compact bone appears at first glance to be solid and uninterrupted closer inspections reveals that the osseous tissue only makes up from 70 95 of the available volume. Spongy bone and compact bone make up the long bones of the human skeleton long bones are longer than they are wide like the tibia and the femur.

Cancellous bone has a higher surface area to volume ratio than cortical bone and it is less dense this makes it weaker and more flexible. Spongy bone also called cancellous or trabecular bone is one of the two types of calcium tissue that make up bones in the human body. The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions.

Spongy bone is usually located at the ends of the long bones the epiphyses with the harder compact bone surrounding it. Compact bone appears solid and spongy bone consists of a web or sponge like arrangement of solidified extracelluar matrix. Beneath the periosteum lie the dense hard layers of bone tissue called compact bone.

Spongy bone also known as cancellous bone or trabecular bone is a very porous type of bone found in animals. Its composition is fibrous rather than solid and it gives bone its resiliency. Spongy bone also called cancellous or trabecular bone provides structural support and facilitates movement of the joints and limbs.
