Detailed explanation-1: -epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone .

Detailed explanation-2: -Answer and Explanation: The end of a long bone is called the epiphysis. A long bone is a bone that is longer than it is wide. Some of the long bones in the human body are the femur, humerus, tibia, metacarpals and phalanges. The epiphysis is rounded and is found where the long bone forms a joint with other bones.

Detailed explanation-3: -The epiphysis is the terminal end of the long bone that is typically responsible for articulation. It is also the primary source of red bone marrow in long bones, which allows erythropoiesis.

Detailed explanation-4: -The epiphysis is the enlarged wide end of a long bone that articulates with other bones at joints; this portion of bone is only found on the ends of long bones. It is widened to strengthen joints and allow for ligaments and tendons to attach. It is separated from the rest of the bone by a growth plate.

Detailed explanation-5: -A hollow medullary cavity filled with yellow marrow runs the length of the diaphysis of a long bone. The walls of the diaphysis are compact bone. The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow.
