What does the term "cortical" refer to?

• A. The inner layer of an organ
• B. The outer layer of a bone or organ
• C. A type of tissue in the brain
• D. An infection in the bone

Answer: (B)

The term "cortical" refers specifically to the outer layer of a bone or organ. In anatomical contexts, "cortex" is used to describe the outer regions of certain structures, such as the cerebral cortex in the brain or the cortical bone surrounding the medullary cavity. This terminology helps in identifying the various layers and types of tissues within organs as well as different components of the skeletal system. In the case of bones, the cortical layer is dense and strong, playing a crucial role in providing structural support and protection to the underlying layers. Recognizing the distinction between cortical and other types of tissue, such as the medullary or inner layers, is essential knowledge for those studying anatomy and surgical instruments, as it influences surgical approaches and instrument selection in procedures involving bone.
