Verified step by step guidance

Step 1: Begin by identifying the anatomical structure in question, which is the radius, one of the two bones in the forearm. The radius is located on the lateral side of the forearm (thumb side).

Step 2: Understand the composition of bones. Bones are made up of several components, including compact bone, spongy bone, articular cartilage, and red bone marrow. Each serves a specific function.

Step 3: Compact bone is the dense, hard outer layer of bone that provides strength and support. It is the major structural component of long bones, including the radius, and is responsible for bearing weight and resisting stress.

Step 4: Spongy bone, also known as cancellous bone, is found inside the ends of long bones and is lighter and less dense than compact bone. It contains spaces that house red bone marrow, which is involved in blood cell production.

Step 5: Articular cartilage is a smooth, slippery tissue that covers the ends of bones where they form joints, reducing friction and absorbing shock. It is not the major component of the radius. Red bone marrow is found within spongy bone and is not the primary structural component of the radius.
