Fill in the blanks. The blank is an elongated flat bone
situated in the center of the chest. It connects to the blank with
cartilage to form the thoracic cage. (A) Clavicle and sternum. (B) Sacral bone and pelvis. (C) Sternum and ribs. Or (D) vertebral column and
ribs.
The thoracic cage, or rib cage, is
made up three components: vertebrae that make up the thoracic region of the
vertebral column; flat, curved bones called ribs; and the sternum, sometimes less
formally called the breastbone.
The thoracic vertebrae provide
anchor points to which the ribs are attached. And each of the upper 10 pairs of
ribs is attached to the sternum through a length of specialized cartilage, which
gives the rib cage some added flexibility. The sternum is a flat bone that
forms connection via cartilage to the ribs, to make up part of the thoracic
cage.
So, the correct answer to this
question is (C) sternum and ribs. The sternum is an elongated flat
bone situated in the center of the chest. It connects to the ribs with
cartilage to form the thoracic cage.
