What classification is used for human bones based on density?

• A. Dense and fragile bones
• B. Compact and spongy bones
• C. Light and heavy bones
• D. Integrated and incorporated bones

Answer: (B)

Bones in the human body can be classified based on their density into two main categories: compact bones and spongy bones. Compact bone, also known as cortical bone, is dense and forms the outer layer of the bone structure. It provides strength and support, allowing for weight-bearing activities and structural integrity. In contrast, spongy bone, also referred to as cancellous bone, is lighter and less dense. It is found primarily at the ends of long bones and within the interior of others, providing support while reducing overall bone weight. This classification is significant in understanding bone health, strength, and the implications for conditions such as osteoporosis, where the density of bone is affected. Therefore, distinguishing between compact and spongy bones is essential in anatomy and physiology, making this classification relevant and accurate.
