Match each location with the type of bone it mainly contains: > Epiphysis of long bone < Inside of flat bone 1. B sic Concepts Use with Chapter 34, Section 34.2 2. The formation of osseous tissue in areas outside of bone is called _____ ossification. Compact bones are also called cortical bones, which contain osteons or Haversian systems. Collectively allow weight transfer, source of quick bone absoprtion and formation. Spongy (trabecular, cancellous) bone External layer of all bones Select ALL choices that apply. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Spongy bone is typically found at the epiphysis (the ends) of a long bone. 4. The compact bone gets its white, smooth structure owing to the … when looking at this question about what spongy bone does or is, spongy bone contains red bone marrow, and this is the location where blood cells are formed. The difference between spongy and compact bones is given below in a tabular column. These two types are classified as on the basis of porosity and the unit microstructure. Bone cells \(osteoblasts\) Produce white and red blood cells and platelets and stores minerals. Space between trabeculae of spongy bone. Types Of Bones In The Human Body - Long Bones - Short Bones - Flat Bones - Irregular Bones - Duration: 1:40. Spongy bone is prominent in areas of bones that are not heavily stressed or where stresses arrive from many directions. Compact and Spongy Bone. Whats Up Dude 134,366 views These trabeculae are located in between red bone marrow. Spongy bone reduces the density of bone and allows the ends of long bones to compress as the result of stresses applied to the bone. Enlarged chondrocytes die and the cartilage matrix is calcified. 1. Categories Uncategorized. This is the type of bone that makes the entire skeleton appear smooth and white, at least at first glance. What is Bone – Definition, Characteristics, Function 2. Spongy bone tissue fills part or all of the interior of many bones. Hyoid bone fractures occur more frequently in young individuals, and in men more than in women 6).

Spongy Bone: Spongy bones occur in the outer layers of a bone. The advantage of the epiphysis being formed of spongy bone is that the bone would still be strong but lightweight. Spongy bone located between two layers of compact bone. Spongy bone has a greater surface area than cortical bone but makes up only 20 percent of bone mass. Strength . Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 6.11). Ectopic. Trabeculae Function. Structure. It makes up around 80 percent of adult bone mass. And as we can remember back to our basic functions of the skeletal system. Compact Bone: Compact bones … They can be found in the ear, nose, larynx, trachea, ribs, and joints. This makes up critically important tendons (connects muscle to bone) and ligaments (connects bones to bones). The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions. Spongy bone is softer and weaker than compact bone, but is also more flexible. Spongy bone is found in the heads. Only compact bone has osteons. Spongy bone is usually located at the ends of the long bones (the epiphysis), with the harder compact bone surrounding it.
