Detailed explanation-1: -Compact bones are present in the outer layer of long bones, while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is their structure and function.

Detailed explanation-2: -Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.

Detailed explanation-3: -Compact bone tissue is composed of osteons and forms the external layer of all bones. Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Four types of cells compose bony tissue: osteocytes, osteoclasts, osteoprogenitor cells, and osteoblasts.

Detailed explanation-4: -What is the difference between compact bone and spongy bone? They have different bone marrow. They are made of different materials. They have different sizes of bone cells.

Detailed explanation-5: -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.
