brjóstvegg

Brjóstvegg is an Icelandic term that translates directly to "chest wall." It refers to the anatomical structure forming the front and sides of the chest cavity in humans and other vertebrates. This complex structure is composed of several key elements, including the ribs, the sternum (breastbone), and the thoracic vertebrae at the back, all of which are connected and protected by muscles and connective tissues.

The primary function of the brjóstvegg is to protect the vital organs housed within the thoracic cavity, such as the heart and lungs, from external trauma. It also plays a crucial role in respiration. The coordinated movement of the ribs and sternum, facilitated by the intercostal muscles, expands and contracts the chest cavity, allowing for the inhalation and exhalation of air.

Diseases and injuries affecting the brjóstvegg can have significant consequences. Fractures of the ribs or sternum can cause pain and make breathing difficult. Conditions like pleurisy involve inflammation of the membranes lining the chest wall, leading to sharp chest pain. Medical conditions such as costochondritis, an inflammation of the cartilage connecting the ribs to the sternum, also affect the brjóstvegg and can be a source of discomfort. Various surgical procedures may involve or impact the brjóstvegg, including thoracic surgery and cardiac procedures. Understanding the anatomy and function of the brjóstvegg is therefore essential in medicine.
