ЛЕКЦИЯ № 14. Thoracic wall
There are 12 thoracic vertebrae. The vertebrae have facets on their bodies to articulate with the heads of ribs; each rib articulates with the body of the numerically corresponding vertebra and the one below it. The thoracic vertebrae have faces on their transverse processes to articulate with the tubercles of the numerically corresponding ribs. Sternum: the manubrium articulates with the clavicle and the first rib. It meets the body of the sternum at the sternal angel an important clinical landmark.
The body articulates directly with ribs 2-7; it articulates interiorly with the xiphoid process at the xiphisternal junction. The xiphoid process is cartilaginous at birth and usually ossifies and unites with the body of the sternum around age 40.
Ribs and costal cartilages: there are 12 pairs of ribs, which are attached posteriorly to thoracic vertebrae.
Ribs 1-7 are termed «true ribs» and attach directly to the sternum by costal cartilages.
Ribs 8-10 are termed «false ribs» and attach to the costal cartilage of the rib above. Ribs 11 and 12 have no anterior attachments, and are therefore classified as both «floating ribs» and false ribs. The costal groove is located along the inferior border of each rib and provides protection for the intercostal nerve artery, and vein, ribs 1, 2, 10, 11, and 12 are atypical. Muscles: external intercostal muscles.
There are 11 pairs of external intercostal muscles. Their fibers run anteriorly and inferiorly in the intercostal spaces from the rib above to the rib below.
These muscles fill the intercostal spaces from the tubercles of ribs posteriorly to the costochondral junctions anteriorly; they are replaced anteriorly by external intercostal membranes. Internal intercostal muscles: there are 11 pairs of internal intercostal muscles. Their fibers run posteriorly and inferiorly in the intercostal spaces deep to the external layer.
These muscles fill the intercostal spaces anteriorly from the sternum to the angles of the ribs posteriorly; they are replaced posteriorly by internal intercostal membranes.
Innermost intercostal muscles: the deep layers of the internal intercostal muscles are the innermost
