ANATOMY

Detailed explanation-1: -There are flat bones in the skull (occipital, parietal, frontal, nasal, lacrimal, and vomer), the thoracic cage (sternum and ribs), and the pelvis (ilium, ischium, and pubis). The function of flat bones is to protect internal organs such as the brain, heart, and pelvic organs.

Detailed explanation-2: -Examples include the skull and rib bones. Flat bones have marrow, but they do not have a bone marrow cavity. The skull is the bony structure of the head and face. The cranium surrounds the brain with the temporal, frontal, parietal and occipital bones.

Detailed explanation-3: -The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis.

Detailed explanation-4: -The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1).

Detailed explanation-5: -Long bone – has a long, thin shape. Short bone – has a squat, cubed shape. Flat bone – has a flattened, broad surface. Irregular bone – has a shape that does not conform to the above three types.
