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).
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.’
Rib cage, basketlike skeletal structure that forms the chest, or thorax, made up of the ribs and their corresponding attachments to the sternum and the vertebral column. The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.
The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
Your rib cage surrounds and protects the vital organs in your chest cavity, your heart and lungs. It expands with your lungs when you breathe. As part of your axial skeleton, your rib cage helps form the trunk of your body. It also serves as an attachment point for core muscles, like your diaphragm.
The ribs are 12 pairs of curved, flat bones that form the thoracic cage or rib cage, the bony structure that shapes the thoracic cavity and protects various organs. Despite being relatively thin and light, these bones are highly resilient.
The human thoracic basket consists of 37 bones: Sternum (1, singular): Also recognized as the breastbone, it is palpable at the center of the chest. This bone articulates with the first 7 ribs. Thoracic vertebrae (12, singular): These comprise the 12 bones in the thoracic spine (T1-T12).
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.
The rib cage is also known as the thoracic cage, and the primary rib cage function is to protect the organs inside the chest. These organs include the heart and lungs, which are two of our...
