Located toward the end of long bone; contains small open spaces which lightens bone

Explanation:
Spongy bone is the porous, lattice-like tissue found toward the ends of long bones (in the epiphyses). Its tiny spaces, formed by trabeculae, light en the bone while still providing strength to handle stress from movement. This spongy structure also houses some of the bone marrow. Compact bone, by contrast, is the dense outer layer around the bone shaft; the medullary cavity is the hollow space in the diaphysis that contains marrow; cartilage is a flexible tissue at joint surfaces and growth areas, not the lightweight, porous bone described here.
