Rib (Fish)

A rib is a bone that forms part of the human chest. It has the shape of an elongated, flat, curved bone that merges anteriorly into the costal cartilage. The ribs protect the human heart and lungs from damage by forming part of the skeleton of the chest.

A person has 12 pairs of ribs. Each rib consists of a head and a neck. The head of the rib articulates with one of the twelve thoracic vertebrae, and the neck meets the costal cartilage, which connects the rib to the sternum.

The first seven pairs of ribs - the true ribs - connect directly to the sternum, while the next three pairs of ribs - the false ribs - have their ends that grow together and form a costal arch connecting them to the underlying ribs.

The last two pairs of ribs are called oscillating ribs and end in the muscles of the anterior abdominal wall, which allows them to move during breathing.

Anatomically, the rib is called costa.

Ribs are bones that form part of the rib cage and protect the heart and lungs. They have an elongated flat curved shape and pass anteriorly into the costal cartilage.

The ribs are part of the skeleton of the chest and form its upper part. They protect the chest organs from damage and injury.

A person has 12 pairs of ribs, each of which consists of a head and a body. The heads of the ribs articulate with the thoracic vertebrae, and the bodies of the ribs articulate with the sternum.

The first seven pairs of ribs are true ribs and connect directly to the sternum through cartilage. The next three pairs of ribs are false ribs, since their ends are fused with the cartilage of the lower ribs.

The last two pairs of ribs are called oscillating ribs or floating ribs. They are not connected to other ribs and end freely in the muscle of the anterior abdominal wall.

The anatomical name of the rib is costa.

Edge

A rib is a bone that forms part of the chest and protects internal organs from damage. It has an elongated flat curved shape and passes into the costal cartilage in front.

Humans have 12 pairs of ribs that form the rib cage skeleton. Each pair of edges consists of one true edge and two false edges. True ribs connect directly to the sternum, and false ribs fuse with the cartilage of the lower ribs and form the costal arch.

The first seven pairs of ribs - true ribs - connect directly to the sternum with the help of costal cartilages, and the next three pairs - false ribs - the ends of their costal cartilages fuse with each other and with the costal cartilages of the underlying ribs, forming a costal arch. The last two pairs of ribs - the oscillating ribs - end freely in the muscles of the anterior abdominal wall, which allows them to move and change the shape of the chest during breathing.

The anatomical name of the rib is costa.
