What type of connective tissue is involved in the structure of joints?

The correct answer is bone or skeletal tissue because this type of connective tissue is fundamental to the formation and function of joints. Joints are the points where bones meet, and they are typically comprised of various structures including bone tissue, cartilage, and synovial membranes, all of which are elements of the skeletal system. Bone connects to other bones at the joints, allowing for movement and stability.

Bone tissue provides the rigid framework necessary for holding the body together and facilitating movement. It is composed of living cells and a mineralized matrix, which provides strength and support. Additionally, cartilage, which is a specialized form of connective tissue present in joints, caps the ends of bones, reducing friction and absorbing shock, further enhancing the functionality of joints.

The other options represent different types of tissue with distinct roles. Skeletal muscle, for instance, is responsible for movement but is not connective tissue. Adipose tissue serves primarily for insulation and energy storage, while marbling refers to the distribution of fat within muscle tissue, affecting flavor and tenderness in meat but not directly related to the structural composition of joints.
