It is highly vascularized and contains red bone marrow. spongy bone: [ bōn ] 1. the hard, rigid form of connective tissue constituting most of the skeleton of vertebrates, composed chiefly of calcium salts. Spongy, porous bone tissue is also called. This process also occurs in the liver and spleen. It is porous and highly vascularized, containing red bone marrow. They are also called cancellous bones. Blood vessels travel through the harder compact bone to the spongy bone, supplying it with the materials necessary to create blood cells. Bone in which the spicules or trabeculae form a latticework, with interstices filled with embryonic connective tissue or bone marrow. 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. @Planch: Actually, the long bone, yes at the ends the epiphysis, do contain spongy bone and compact bone and red marrow. Acromion. 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 also called Twenty percent of your skeleton is composed of a less rigid bone called trabecular (spongy bone), while the other eighty percent is dense, strong cortical (compact bone). It is characterized by a lattice-like matrix network called trabeculae (Latin for little beam) that gives it its spongy appearance. It is found in the long bones and it is surrounded by compact bone. The interior portion of the long bones is composed of spongy bones. c. Cancellous bone d. Compact bone e. Spongy bone. The cortical plates are least in the maxillary region and the highest are seen in the molar region of the mandibular bone. Apparenlty the middle of many bones is actually hollow! Spongy bone. Spongy bone tissue fills part or all of the interior of many bones. Spongy bone is sometimes called cancellous bone or trabecular bone. However, yellow bone marrow can be converted back to red bone marrow if necessary, in the case of severe blood loss. In comparison, it makes sense that the skeleton of a chimpanzee is almost entirely composed of spongy bone. While compact bone is denser and has fewer open spaces, spongy bone is ideal for making and storing bone marrow within the lattice-like trabeculae network. Cortical bone contains cortical plates which have perforations in the anterior teeth, for the entry of blood vessels into the inner parts of the teeth. Spongy Bone: Spongy bone is the osseous tissue, which fills the interior cavity of bones, consisting of mineralized bars called trabeculae. Linguistics and Anthropology. The cortical plates are least in the maxillary region and the highest are seen in the molar region of the mandibular bone. Which of the following statements is NOT true about spongy bone? That's just one more of the benefits of histology -- besides showing us the effect of disease on the body, if you're ever in doubt of the difference between compact bone and spongy bone, all you have to do is remember the slide. The results of the research show that lower trabecular bone density in modern humans is a recent event, and is probably caused by increasingly sedentary lifestyles and a reliance on technology. 2.Compact bone is also called cortical bone while spongy bone is also called cancellous bone. A. Here's a trivia question for you: What contains the spongy bone in adults? Spongy Bone. Composition. It is found in the long bones and it is surrounded by compact bone. Cancellous bone, also called trabecular or spongy bone, is the internal tissue of the skeletal bone and is an open cell porous network. Spongy Bone. Trabeculae are found in many different parts of the body, but they are most often made of collagen. It is porous and highly vascularized, containing red bone marrow. In this sense also called spongy substance 2. The bone matrix, or framework, is organized into a three-dimensional latticework of bony processes, called … The large surface area and high vascularity of cancellous bone make it ideal for metabolic activity, such as ion and nutrient exchange. Spongy (Cancellous) Bone Structure: Spongy bone is also called cancellous bone or trabecular bone. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = … Retrieved from https://biologydictionary.net/spongy-bone/. Spongy bone is also found inside the vertebrae, ribs, skull and in bones of joints. For example, the difference between a healthy spongy bone and a bone in someone who has undergone bone cancer, or even osteoporosis, is fascinating. The red marrow supplies sponge bone with blood and also produce blood cells. The spongy bones are also called Cancellous bones or the Trabecular bones. Spongy bone Compact bone SPONGY BONE COMPACT BONE . Spongy bone, also known as cancellous bone, is less dense than compact bone and is composed of a honeycomb-like network of bones called trabeculae. She is a graduate of UCLA, where she majored in B. Functions of Spongy Bone Storage of Bone Marrow. Visit BYJU’S to learn more differences. Online Online Learning. The bone marrow fills up the open spaces between the trabeculae. Cancellous bone makes up a larger portion of the bone than the external compact bone tissue. Minute spikes or plates of bone tissue, called trabeculae, give spongy bone a latticelike appearance. About 20% of the human skeleton is spongy bone. 4.Compact bones are tough and heavy while spongy bones … 3.Compact bones are made of osteons while spongy bones are made of trabeculae. Cancellous bone, also called trabecular or spongy bone, is the internal tissue of the skeletal bone and is an open cell porous network. Their density differs by … 2.Compact bone is also called cortical bone while spongy bone is also called cancellous bone. The shafts found in long bones are also compact bones. Spongy, porous bone tissue is also called cancellous bone.. Cancellous bone is found in bones that aren't generally under significant stress like in the shoulder blades, ribs, parts of the skull, and at the ends of long bones. 2. The modern human skeleton is unique in that it has a low trabecular density compared to its size. Compact bone is also called dense bone. When old and damaged red blood cells are ready to die, they return to the bone marrow, where they are phagocytized by macrophages. Spongy bone often contains red bone marrow, the site of production of blood cells. D. It is found in the bones of joints. Figure 5.4. The trabeculae (truh-bek u-lee; little beams) are the small needlelike pieces of bone. I actually had a human anatomy and physiology lecture about this today.
