Pulmonary Sulcus [Sulcus Pulmonalis, Pna; Sulcus Pulmonalis (Thoracis), Bna]

The pulmonary groove, also known as Sulcus Pulmonalis, Pna or Sulcus Pulmonalis (Thoracis), Bna, is a wide groove-like depression between the thoracic vertebral bodies and the inner surfaces of the ribs. This groove is adjacent to the vertebral part of the medial surface of the lungs.

The pulmonary sulcus is of great importance for the anatomy and physiology of the lungs. Firstly, it is the attachment point for the pulmonary ligamentous apparatus, which supports the lungs in the correct position in the chest cavity. This ligamentous apparatus also provides stability to the lungs during breathing and body movement.

In addition, the pulmonary sulcus serves as the boundary between the upper and lower lobes of the lung. This is important for diagnosing and treating lung diseases such as lung cancer or pneumonia. Different types of lung tumors may be located in different parts of the pulmonary sulcus, and this can help doctors determine the exact location of the tumor or infection.

In addition, the pulmonary sulcus is also the site of passage of large vessels and nerves that provide blood supply and innervation to the lungs.

In conclusion, the pulmonary sulcus is an important structure in the anatomy of the lungs, which plays an important role in maintaining the correct position of the lungs, ensuring their stability and is an important marker for the diagnosis and treatment of lung diseases.

The pulmonary sulcus (Sulcus pulmonalis) is a wide groove-shaped depression located between the bodies of the thoracic vertebrae (vertebrae thoracicae) and the inner surfaces of the lungs (pulmones). It is an important anatomical structure that plays an important role in the functioning of the lungs and chest.

The pulmonary groove is formed by two layers of muscles: the thoracic diaphragm (diaphragma thoracis) and the costal muscles (musculi costales). The thoracic diaphragm is a muscle that separates the chest and abdominal cavities and is involved in the breathing process. The rib muscles are located on the inner surface of the ribs and are responsible for their mobility.

The vertebral artery (arteria vertebralis) runs along the pulmonary groove, which supplies blood to the spine and chest. Also running along the groove are nerves that provide sensation and innervation to the chest and lungs.

In addition, the pulmonary sulcus is the attachment site for several organs and structures of the chest, such as the heart, lungs, esophagus, trachea and bronchi. Specifically, the pulmonary artery, which carries blood from the heart to the lungs, is attached to the lateral wall of the pulmonary sulcus.

The importance of the pulmonary groove is that it provides structural support for the lungs and chest cavity. It also plays an important role in breathing by providing space for the lungs and airways to move. In addition, it serves as an attachment site for important structures and organs, making it an important anatomical landmark.

Thus, the pulmonary groove is a broad and important anatomical structure of the chest that provides structural and functional support to the lungs and other organs of the chest cavity, and also plays an important role in the process of breathing and the functioning of the chest in general.
