Structure Of The Rib Cage How Many Ribs In Human Body What In this video we discuss the structure of the rib cage or thoracic cage. we cover the different bones that make up the rib cage and some of the functions of. The human rib cage is made up of 12 paired rib bones; each are symmetrically paired on a right and left side. of all 24 ribs, the first seven pairs are often labeled as ‘true.’. these bones.
Rib Cage Human Anatomy Organs The ribs. the ribs are a set of twelve paired bones which form the protective ‘cage’ of the thorax. they articulate with the vertebral column posteriorly, and terminate anteriorly as cartilage (known as costal cartilage). as part of the bony thorax, the ribs protect the internal thoracic organs. they also have a role in ventilation; moving. The ribs perform vital functions in the body, protecting organs and supporting the breathing process. the vast majority of human beings are born with 24 ribs, 12 on each side of the body. contrary. The human rib cage comprises 37 bones: sternum (1, unpaired): it is also known as the breastbone and can be felt at the center of the chest. this bone articulates with the first 7 ribs. thoracic vertebrae (12, unpaired): these are the 12 bones in the thoracic spine (t1 t12). each vertebra articulates with its corresponding ribs to shape the rib. False ribs are the next 3 pairs (8th, 9th, and 10th ribs). their costal cartilages join with that of the 7th rib to indirectly connect to the sternum. floating ribs are the last 2 pairs (11th and 12th ribs) with no articulation with the sternum. the second mode of classifying ribs is based on their structure and anatomy variations.

The ribs are curved, flat bones which form the majority of the thoracic cage. they are extremely light, but highly resilient; contributing to their role in protecting the internal thoracic organs. there are twelve pairs of ribs, all of which articulate with the vertebral column. however, only seven have a direct articulation with the sternum. The sternum is a long, flat bone that forms the front of the rib cage. the cartilages of the top seven ribs (the true ribs) join with the sternum at the sternocostal joints. the costal cartilage of the second rib articulates with the sternum at the sternal angle making it easy to locate.
