The term spongy comes from the fact that it is a highly vascularized and porous tissue. This bone is highly vascularized and consists of red bone marrow. Bone marrow is a semi-solid tissue found within the spongy or cancellous portions of bones. Find answers now! Blood vessels travel from the harder compact bone toward the spongy bone, by supply the materials which are necessary for the production of blood cells. Bone can be divided into two types: compact and spongy. Osteocytes located to close to the blood vessel, which can take on nutrients and expel the waste material with the help of tiny interconnecting channels found on the surface of trabeculae, known as Canaliculi. This faster production of red blood cells is possible by the highly vascularized nature of spongy bone that can transfer the adequate amount of glucose, amino acids, lipids, and trace elements, which is necessary to make red blood cells. This bone also presents in the ribs, inside the vertebrae, in the joint bones, and in the skull. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Usually, spongy bone is situated at the end of long bones, with the surrounding of harder compact bone. It is done by this process which the long bones in a human embryo develop. The spongy bone is made up of cells, known as Osteocytes which lie in small cavities called Lacunae. Spongy Bone Spongy bone, oftentimes referred to as the cancellous bone, is the soft and porous bone tissue situated in the inner part of the bone. Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. Usually, spongy bone is situated at the end of long bones, with the surrounding of harder compact bone. During the usage of these screws, we need to cut the skin deeply and require more extensive spaced threads as compared to other animal tissue screw. It is made of tightly packed cells so it is very, very dense. Red bone marrow is found … It makes sense that the skeleton of a chimpanzee is almost made up of spongy bone. It is simply a collection of the hard huge calcareous connective tissue of which most adults vertebrates body is principally composed of. isn't really spongy; really it's hard but it has lots of holes- which gives it the appearance of a sponge. The pores that make it look spongy are filled with red bone marrow, the type which creates our red blood cells. Cancellous bone is the spongy interior layer of bone that protects the bone marrow.It is also be called a spongy bone or trabecular bone. By testing it shows that the early human bones were contained a higher percentage of spongy bone compare to modern human bones. The human skeleton is composed of about 20% of spongy bone. Spongy bone is typically found at the epiphysis (the ends) of a long bone. They’re most typically utilized in the metaphysis of long bones. In birds and mammals, bone marrow is the primary site of new blood cell production or haematopoiesis. It is lighter, less dense, and more flexible than compact bone. The trabeculae of the spongy bone work to form along with lines of stress, which gives the bone strength and the flexibility in this area. Spongy bone is found throughout the body and in virtually every long bone, short bone and sesamoid or circular bone. The blood mineral contents must be regulated in order to sure the proper functioning of muscles and the nervous system. 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. Bones make up the human skeletal system and are used to support the body and help provide movement. This bone also presents in the ribs, inside the vertebrae, in the joint bones, and in the skull. The blood is produced in this very bone, which is responsible for protecting the internal body parts. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pelvis. Spongy bone is also called cancellous or trabecular bone. B) The matrix of the bone contains osteoclasts and chondroblasts. The diaphysis elongates and a medullary cavity forms 5. Spongy bone is found on the inside of some bones, and it is surrounded by the stronger, more protectiv… A bone collar forms around diaphysis of cartilage 2.central cartilage in diaphysis calcifies, the develops cavities 3.The periosteal bud invades the internal cavities and spongy bone forms 4. Inside compact bone B. Thereafter, fat tissue gradually replaces the red marrow, which in adults is found only in the vertebrae, hips, breastbone, ribs, and skull and at the ends of the long bones of the arm and leg; other cancellous, or spongy, bones and the central cavities of the long bones are filled with yellow marrow. Bone is not uniformly solid, but consists of a flexible matrix (about 30%) and bound minerals (about 70%) which are intricately woven and endlessly remodeled by a group of specialized bone cells. Compact bone tissue forms the outer layer of all bones while spongy or cancellous bone forms the inner layer of all bones. Spongy bone tissue does not contain osteons.

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 outer surface of a bone is compact bone, and the inner more porous portion is cancellous (spongy) bone. The tissues in spongy bone are less densely arranged, thereby giving the bone its name. The lacunae and their osteocytes are present in trabeculae matrix on the bone with the bone marrow. Spongy bone actually looks like a sponge. Spongy bone corresponds to the areas with the lacunae and accounts for the remaining 20% of total bone mass, but has nearly ten times the surface area of compact bone. In spongy bone the osseous tissue is arranged into trabeculae, which are the interconnected columns of osseous tissue which create the sponge-like grid of spongy bone. It is what gives the bone strength, as well as its smooth, white, solid appearance. Compact vs Spongy Bone We can also say that skeleton is a collection of numerous rigid animal substances or structures like baleen or ivory. It is found in the long bones and it is surrounded by compact bone. Compact bone is organized into subunits called osteons. Spongy bone can also convert to the compact bones through the osteoblasts action. Materials, design and manufacturing technologies for orthopaedic biomaterials: a review Osteoclasts are usually found on the surface of the tissue. The low density and low weight of spongy bone balance out the heavier and denser compact bone in order to reduce the overall weight of the skeleton.
