Verified step by step guidance

Understand the structure of spongy bone: Spongy bone, also known as cancellous bone, is characterized by a porous, lattice-like structure composed of trabeculae. These trabeculae are the small, needle-like or flat pieces of bone that form the network within spongy bone.

Identify the function of trabeculae: Trabeculae provide structural support and help distribute stress and strain throughout the bone. The spaces between trabeculae are crucial for housing various types of bone marrow.

Differentiate between types of bone marrow: Bone marrow is a soft tissue found within bones. There are two types: red bone marrow, which is involved in hematopoiesis (production of blood cells), and yellow bone marrow, which primarily stores fat.

Determine what is typically found in spongy bone: In adults, red bone marrow is typically found in the spaces between trabeculae in spongy bone, especially in areas such as the pelvis, ribs, vertebrae, and ends of long bones. Yellow bone marrow is more commonly found in the medullary cavity of long bones.

Review other options: Compact bone is dense and forms the outer layer of bones, not found between trabeculae. Hyaline cartilage is a type of cartilage found in joints, respiratory structures, and other areas, but not typically in the spaces between trabeculae in spongy bone.
