Which type of bone is also known for its role in strength, accommodating stress, and having blood vessels?

Cortical bone, also referred to as compact bone, plays a vital role in providing strength and support to the skeletal structure. It forms the outer layer of bones and is dense, making it effective at bearing weight and withstanding stress during various physical activities. This type of bone is not only important for structural purposes but also contains Haversian canals, which allow for the passage of blood vessels, ensuring that the bone tissue receives essential nutrients and oxygen. This vascularization is crucial for maintaining bone health and facilitating the repair processes.

The other options represent different types of bones with distinct characteristics and functions. Spongy bone, for instance, is lighter and found primarily at the ends of long bones and within the interiors of others, but it does not provide the same level of strength or weight-bearing capacity as cortical bone. Sesamoid bones are small, round bones embedded in tendons, and while they may aid in joint movement and distribute weight, they do not have the same structural role. Overall, the properties of cortical bone—its density, potential for accommodating stress, and associated blood vessels—underscore its importance in the skeletal system.
