Detailed explanation-1: -The bone marrow makes blood cells and stores fat. Spongy bone (also called cancellous bone) is made up of small, needle-like pieces of bone arranged like a honeycomb. Spongy bone helps to lessen the weight of a bone while still providing strength. Cartilage covers the end of bones.

Detailed explanation-2: -Cancellous bone is also called trabecular bone, or spongy bone. This bone tissue is usually found at the end of long bones and inside the bones of the vertebrae. The trabeculae (truh-bek u-lee; little beams) are the small needlelike pieces of bone.

Detailed explanation-3: -Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones.

Detailed explanation-4: -Bone marrow fills the cavities of long bones and occupies the spaces of spongy bone. Yellow marrow, consisting mostly of fat, is found in the central cavities of long bones.

Detailed explanation-5: -Spongy bone is composed of small needlelike or flat pieces of bone called trabeculae and has much open space.
