Detailed explanation-1: -Flat bones provide broad surfaces for attachment of muscles and protection for internal organs. Examples of flat bones are bones of the skull, ribs, shoulder blades, the breastbone and pelvis.

Detailed explanation-2: -Flat bones are broad bones that provide protection or muscle attachment. They are composed of two thin layers of compact bone surrounding a layer of cancellous (spongy) bone. These bones are expanded into broad, flat plates, as in the cranium (skull), ilium (pelvis), sternum, rib cage, sacrum, and scapula.

Detailed explanation-3: -These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.

Detailed explanation-4: -Flat bones are thin and relatively broad bones that are found where extensive protection of organs is required or where broad surfaces of muscle attachment are required. Examples of flat bones are the sternum (breast bone), ribs, scapulae (shoulder blades), and the roof of the skull (Figure 19.16).

Detailed explanation-5: -Flat Bones Protect Internal Organs 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.
