Which type of bode provides a large, flat surface area for muscle attachment? Flat bones are generally thin and provide extensive surfaces for muscle attachment. An example of a flat bone is the scapula or the shoulder blades. 3. Describe the location, composition, and function of the epiphyseal plate. The epiphyseal plate is a layer of hyaline cartilage that allows the bone to grow in length. It is located in the Metaphysis of the growing bone. When the bone is finished growing, the hyaline cartilage is turned into osseous tissue. 4. Which kind of bone marrow is in spongy bone tissue? Red bone marrow is located in spongy bone tissue. 5. Which ossification method would form a femur? The femur, which is a long bone, is formed by endochondral ossification which is the replacement of cartilage by osseous tissue. Most bones of the body are formed by this process. 6. Why is bone remodeling necessary when a person reaches adulthood? Bone remodeling allows for new osseous tissue to replace older osseous tissue before deterioration sets in. It also allows for bones to heal and creates a stronger bone. It also restructures the bone extracellular matrix, where the shape of a bone is changed slightly, so that the bone can support more stress, be stronger, and/or thicker. 7.
