What does excess postexercise oxygen consumption represent?

Choice A reason: Flat bones are typically thin and broad, such as the sternum or skull bones. They do not match the described dimensions of Emily’s bone.

Choice B reason: Irregular bones have complex shapes that do not fit into other categories, such as vertebrae. The bone described is not irregular.

Choice C reason: Short bones are roughly cube-shaped and found in areas like the wrist and ankle. A bone that is 3 inches long does not fit this category.

Choice D reason: Long bones are characterized by being longer than they are wide, typically found in the limbs. A bone that is 3 inches long and 1 inch wide fits this classification.

Choice E reason: Sesamoid bones are small, round bones embedded in tendons, like the patella. The described bone does not fit this category

Choice A reason: Epiphysis and diaphysis refer to regions of a long bone—the ends and shaft respectively—not to the coverings of bone surfaces.

Choice B reason: This reverses the anatomical regions but still does not address the coverings of bone surfaces.

Choice C reason: Compact bone and spongy bone are types of bone tissue, not the membranes that line or cover bone surfaces.

Choice D reason: The periosteum is a dense fibrous membrane that covers the external surface of bones, providing attachment points for tendons and ligaments and housing blood vessels and nerves. The endosteum lines the internal surfaces, including the medullary cavity, and plays a role in bone growth and remodeling.

Choice E reason: This reverses the correct anatomical relationship. The endosteum lines the internal surface, not the external.
