The tenth rib is one of the three false ribs of the thoracic cage. It is considered an atypical rib because it only has one articular facet on its head. The tenth rib is classified as a flat bone and includes the following bony features:

2025年2月13日 · As part of the bony thorax, the ribs protect the internal thoracic organs. They also have a role in ventilation; moving during chest expansion to enable lung inflation. In this article, we shall look at the anatomy of the ribs – their …

The eleventh and twelfth ribs, the floating ribs, have a single articular facet on the head, which is of rather large size. They have no necks or tubercles, and are pointed at their anterior ends. The eleventh has a slight angle and a shallow costal groove, whereas the twelfth does not.

The tenth rib is typically shorter than the ribs above it and has a more variable attachment and mobility. It is also associated with the tenth intercostal nerve, which runs along its lower border. The rib's anatomy is important in surgical contexts, such as during lumbotomy or when harvesting costal cartilage for reconstructive procedures.[3-4]

2023年8月16日 · The 10th rib courses around your body and attaches to a network of cartilage with the eighth and ninth ribs above it. This cartilage then attaches to your lower sternum. These ribs are also called "false ribs" since they do not attach directly to the sternum. Ribs number 11 and 12 are considered atypical because they do not attach to the sternum.

The body (shaft) of tenth rib is the long, curved part of the bone that extends from its neck to its costal end. It is flattened in appearance, where it has external and internal surfaces and superior and inferior borders. The body of tenth rib consists of the costal groove and the angle and provides attachment sites for the intercostal muscles.

2016年9月9日 · The thorax includes 12 pairs of ribs (1–12; left ribs are numbered in Figure 6.1; the ninth, tenth and 11th left ribs are superimposed in this view). Each rib articulates anteriorly, through a costal cartilage, with either the sternum (13) for the first seven ribs, or with the rib above (for the eighth to tenth ribs).

If the tenth rib articulates with both bodies of the mentioned vertebrae, it is classified as a typical rib - its head will have two articular demi-facets. If the tenth rib articulates with only the body of the tenth thoracic vertebra (T10), it will be classified as an atypical rib.
