Assignment 3.9 The anatomy of compact bone is strong and dense whereas cancellous bone is spongy with holes that contain the bone marrow. Trabeculae is the meshwork inside the cancellous bones that gives it that spongy appearance. The trabeculae give the bone strength without adding too much weight. Compact bones make up 80% of the body and Cancellous bones make up the remaining 20%.
Compact bone is the main component in the long bones of the arms and legs, where its great strength is needed. These bones make up the cortex which is the outer shell of most bones. Compact bones are formed from osteons which are units of bone material and blood vessels. This is what allows compact bone to remain hard and still receive nutrients.
