Where is cortical (compact) bone frequently found?

• A. In the marrow cavity
• B. In the femoral neck and fingers
• C. In regions of low mechanical stress
• D. In the pelvic girdle only

Answer: (B)

Cortical bone, also known as compact bone, is characterized by its dense structure and is typically found in areas that require strength and support. This type of bone is crucial in the long bones of the body, where it provides the necessary rigidity and resistance to bending and deformation. The femoral neck is a critical area where cortical bone is located, as it must withstand significant forces during activities such as walking or running. The fingers also contain cortical bone, particularly in the phalanges, which support grip and dexterity. These regions experience more mechanical loading and stress, necessitating a stronger bone structure to prevent fractures. Understanding the distribution of cortical bone in these locations highlights its role in supporting higher levels of mechanical stress, contrasting with other areas of the body that may not require such strength. This reinforces the idea that cortical bone is often strategically located in parts of the skeleton where durability and stability are essential.
