The focus of this post will be the sternum, which is do up of the Manubrium, Corpus Sterni (or Gladiolus) and the Xiphoid Process alongside a whole step at the knits, all of which help to form the rib henhouse. It is requisite to note here that variation in the number of ribs, as of the vertebrae discussed previously, can differ in people and in archeologic populations (Mays 1999: 15). The function of the rib cage, as the main upper fibre of the organic structure in the gentlemans gentleman body, is to protect the vital organs that lie within the protective enclave of the ribs. They include the majority of the torso organs such as the heart, liver, lungs, kidneys and partially the intestines. The rib cage also helps breathing by the function of the intercostal muscles lifting and forbidding the rib cage, aiding inhalation and exhalation. The ribs are attached dorsally to the vertebrae, with articulating facets for the distinction devastation of the ribs for the thoracic vertebrae (White & Folkens 2005).
Main Elements of The Rib Cage
Rib Cage Anatomy, Terminology and Elements
The number of ribs present in the typical human skeleton is of 12 paired rib elements (a total of 24 altogether).
Ribs project from proximal articulating facets with thoracic vertebrae, slant forward, and depending on the rib pair under consideration, articulate at the distal end with either the sternum, hard cartilage or float freely (Jurmain et al 2011). Ribs usually increase from size from rib 1 to rib 7, and decrease in size from rib 7 to rib 12 (White & Folkens 2005: 185).
Posterior View Of Ribs & Articulating Vertebrae
The Upper 7 ribs on each side of the cage connect distally directly to the sternum via cartilage, whilst the 8th, 9th and 10th ribs connect indirectly to the sternum. The inhabit 2 ribs are often called floating ribs because they have succinct cartilaginous ends that lie free in sides of the body contend (White & Folkens 2005: 181).
