Explanation: 

Detailed explanation-1: -Spongy bone is commonly found at the end of long bones, as well as the ribs, skull, pelvic bones and vertebrae. Located in the spaces, between the trabeculae of some spongy bones is red bone marrow. Blood vessels within red bone marrow supply osteocytes of spongy bone and aid in removing waste products.

Detailed explanation-2: -The trabeculae of spongy bone tend to form along lines of stress, giving the bone strength and flexibility in that area. Spongy bone is also present in the joints of the body and acts as a shock absorber when we walk, run and jump.

Detailed explanation-3: -Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.

Detailed explanation-4: -A typical long bone shows the gross anatomical characteristics of bone. The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled with spongy bone.
