Spongy bone, also called cancellous or trabecular bone, provides structural support and facilitates movement of the joints and limbs. Compact bone is organized into subunits called osteons. It occurs when blood vessel crowds together by the trabecular matrix and they condense. Spongy bones are weaker and softer as compared compact bone, but it is much flexible too. As its name suggests, spongy bone is porous like a sponge, containing an irregular network of spaces. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) ( [link] ). 1 Questions & Answers Place. The compact bone is denser with having few open spaces, the spongy bone is good for form and stores bone marrow across the lattice-like trabeculae network.

What is Bone:�Bone is basically one of the hardest parts of the skeleton within the Vertebrate. The blood mineral contents must be regulated in order to sure the proper functioning of muscles and the nervous system. Also, the manufacturing of red and white blood cells takes place in the spongy bone. 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. 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. The lacunae and their osteocytes are present in trabeculae matrix on the bone with the bone marrow. It structurally resembles honeycomb and accounts for about 20% of bone matter in the human body.. Cancellous bone refers to the spongy interior layer of bone that protects the bone marrow. A) medullary cavity B) metaphysis C) spongy bone D) epiphysis. Spongy bone is found throughout the body and in virtually every long bone, short bone and sesamoid or circular bone. Bone can be divided into two types: compact and spongy. 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. Red bone marrow is found … Spongy bone also lies in joints and work as a shock absorber when we jump, walk, or run. • Compact bones constitute almost 80% of total weight of human skeleton while spongy bones constitute nearly 20% of total weight of human skeleton. 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. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. Inside compact bone B. Cancellous bone, also known as spongy or trabecular bone, is one of the two types of bone tissue found in the human body. 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. The modern skeleton is unique because it has a low trabecular density as compare to its size. Performance & security by Cloudflare, Please complete the security check to access. Compact bone is found in the shaft (or diaphysis) of a long bone and the surface of the flat bones, while spongy bone is found in the end (or epiphysis) of a long bone. You may need to download version 2.0 now from the Chrome Web Store. Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. It is found in most areas of bone that are not subject to great mechanical stress. What Is Bone Marrow? when the old and damaged red blood cells are near to die, they return to bone marrow and here they phagocytized by the macrophages. The blood is produced in this very bone, which is responsible for protecting the internal body parts.
