Compact bone, also known as cortical bone, is a denser material used to create much of the hard structure of the skeleton. As seen in the image below, compact bone forms the cortex, or hard outer shell of most bones in the body. The remainder of the bone is formed by cancellous or spongy bone. Compact bone is formed from a number of osteons, which ...
The compact bone is the main structure in the body for support, protection, and movement. Due to the strong nature of compact bone, compared to spongy bone, it is the preferred tissue for strength. Spongy bone is used for more active functions of the bones, including blood cell production and ion exchange. However, compact bones also serve a functi...
Cancellous Bone– The softer, less dense tissue that makes up the ends of bones and creates blood cells.Osteons– Functional units of compact bone, created by a network of bone cells and blood vessels.Osteocyte– A cell which function to maintain and repair bone tissue.Osteoblast– Cells which lay down new bone tissue, adding the matrix.1. Which of the following statements about bones is true? A. Osteocytes only exist in cancellous, or spongy bone. B. The difference between cancellous and cortical bone is mainly density, which affects function. C.Compact bone does not require oxygen, as no cells exist within it. 2. Oh no!

Compact bone is dense so that it can withstand compressive forces, while spongy bone (also called cancellous bone) has open spaces and is supportive, but also lightweight and can be readily remodeled to accommodate changing body needs.
