where bone elongation occurs. At the end of the bone is the epiphysis, which in young people is separated from the metaphysis by the physis, or growth plate. The inner part of the bone is the diaphysis, then the actual inside, the medullary cavity is not actually hollow. epiphysis: branching plates that form web-like appearance of spongy bone: trabeculae: what's found inside the spaces in spongy bone? How much blood can be lost from a femur... What bones make up the appendicular skeleton? Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the epiphyseal plate (growth plate), a layer of hyaline (transparent) cartilage in a growing bone. The Clara cell is found in the terminal bronchioles. These two types are classified as on the basis of porosity and the unit microstructure. Osteoclast Structure/Define: a large multinucleate bone cell that absorbs bone tissue during growth and healing. bone marking. 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. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) ( Figure 6.13 ). Cortical bone ��� These create rod and... Our experts can answer your tough homework and study questions. 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. Bone can either be spongy or compact. All other trademarks and copyrights are the property of their respective owners. But in man-made structures such as concrete pillars, materials are typically volumetrically homogenous. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone. Which of the following options is correct? Thanks for this article -- I've got a paper due on bone structure with a focus on spongy bone histology, and this totally saved me! So in due time it will be somewhat hollow, but it will never be completely hollow because there will always be some red marrow in the medullary cavity. the spongy bone. Bronchi, Bronchial Tree, & Lungs Bronchi and Bronchial Tree. @Planch: Actually, the long bone, yes at the ends the epiphysis, do contain spongy bone and compact bone and red marrow. It is lighter, less dense, and more flexible than compact bone. These sorts of tissues can also be found in ��� sphenoid bone. Examples of long bones are_____ 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. Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. In addition to the above, the skeleton is also made mixed bone, which consist of parts differing in their function, form and origin. Does not have osteon instead bone is structured as an open network of trabeculae Trabeculae is filled with red bone marrow Yellow bone marrow—found in spongy bones; yellow because it stores fat What is the structure of the periosteum? Bone is part of the skeletal system that provides support and movement of the body, as well as protecting the organ inside the body. When I was studying bone health in university, and it's really scary to see some of the unhealthy spongy bone samples. Bone in human and other mammal bodies is generally classified into two types 1: Cortical bone, also known as compact bone and 2) Trabecular bone, also known as cancellous or spongy bone. Bone marrow is a soft connective tissue that produces blood cells. The bone marrow of a typical adult is half red and half yellow. 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. Compact bones are heavy and tough as they store calcium in them, contributing to over 80% of total human skeleton weight. I actually had a human anatomy and physiology lecture about this today. However, their surface area is ten times larger than that of compact bones in the human skeleton. Share it!
