False ribs

False Ribs

The human rib cage is a complex structure that protects vital organs in the thoracic cavity. It is composed of 24 ribs, 12 on each side, and is divided into three categories: true ribs, false ribs, and floating ribs. This article focuses on the false ribs, which are the 8th, 9th, and 10th pairs of ribs in the human body.

Anatomy

False ribs, also known as vertebrochondral ribs, are indirectly attached to the sternum, unlike the true ribs which are directly attached. They connect to the sternum through the costal cartilage of the rib above them. This indirect attachment allows for greater flexibility and movement, which is essential for respiration and other bodily functions.

Function

The primary function of the false ribs, like all ribs, is to protect the vital organs in the thoracic cavity. These include the heart, lungs, and parts of the digestive system. In addition, the false ribs also play a crucial role in respiration. Their ability to move and flex allows the lungs to expand and contract, facilitating the process of breathing.

Clinical Significance

Injuries or conditions affecting the false ribs can have serious implications. Rib fractures are common and can occur as a result of trauma, such as a fall or a blow to the chest. Pain, difficulty breathing, and potential damage to internal organs are some of the complications that can arise from a fractured false rib.

Costochondritis, an inflammation of the costal cartilage, can also affect the false ribs. This condition can cause chest pain that may be mistaken for a heart attack. Proper diagnosis and treatment are essential to manage this condition and prevent further complications.
