Structure Of The Rib Cage - How Many Ribs In Human Body - What Is The Sternum
9 Interesting Facts About the Ribs
The ribs partially enclose and protect the chest cavity, where many vital organs including the heart and the lungs are located. The rib cage is collectively made up of long, curved individual bones with joint-connections to the spinal vertebrae. At the chest, many rib bones connect to the sternum via costal cartilage, segments of hyaline cartilage that allow the rib cage to expand during respiration. Although fixed into place, these ribs do allow for some outward movement, and this helps stabilize the chest during inhalation and exhalation. 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.
Ribs are not just an incredibly tasty order on the menu at the nearest steak house: These bony spindles in your torso attach to your sternum breast bone to protect your lungs, heart, spleen, and most of the liver and help with giving shape to your chest cavity, which assists in breathing. Ribs are protective on the one hand, but if badly broken, your ribs can turn lethal to you, piercing your organs. The ribs allow chest expansion for breathing, Martinez explains. The human skeleton has 12 pairs of ribs. Working from the top of the torso down, ribs 1 to 7 are considered "true ribs," as they connect directly from the spine to the sternum, Martinez says. Ribs 8 to 10 are called "false ribs" because they don't connect directly, but have cartilage that attaches them to the sternum.
The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates , that encloses and protects the heart and lungs. In humans, the rib cage, also known as the thoracic cage , is a bony and cartilaginous structure which surrounds the thoracic cavity and supports the shoulder girdle to form the core part of the human skeleton. A typical human rib cage consists of 24 ribs in 12 pairs, the sternum and xiphoid process , the costal cartilages , and the 12 thoracic vertebrae. Together with the skin and associated fascia and muscles , the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back. Ribs are described based on their location and connection with the sternum. All ribs are attached behind to the thoracic vertebrae and are numbered accordingly one to twelve.
By Robert S. Root-Bernstein Friday, September 01, As all good teachers know, students will work much harder for extra-credit points than at the assigned task. I like to take advantage of this convenient trait in my introductory course on evolution. Once my students--nonscience majors at a midwestern land-grant university-- understand the basic terms, I offer additional points for answering the questions I really want them to investigate. Find a dozen differences between the skeletons of a chimpanzee and a human being, I challenge them; tell me how a human female skeleton differs anatomically from a male. I say usually because seven years ago, the first time I taught the course, I got a surprising answer that still crops up with alarming regularity.
