Deep pectoral fascia (f. PECTORALIS profunda)

The deep pectoral fascia lies immediately beneath the superficial pectoral fascia and covers the anterior surface of the chest. The structure of the deep thoracic fascia is a continuous part of the fascial sheath of the limb in the sense that it begins and ends at the tendons. Located in close proximity to the longissimus muscles of the chest wall.

The anatomical structure of the deep thoracic facies corresponds to the position of the anterior chest wall and the position of large masses of muscle tissue covering the chest. The pectoral girdle fascia is covered by the short and long pectoral fascia, which are closely connected to the pectoral muscles. The deep pectoral fascia is divided into two thin shells - the internal and external oblique intercostal fascia. The external oblique intercostal fascia is closely adjacent to the pleura, entering between the air and the pleura of the chest. The internal oblique intercostal space covers the ribs and connects to the tendons of the transverse muscles. The fascia pulls the tendons tightly, as well as the large muscles. Along the sternum there is a narrow superficial part of the serratus anterior muscle. This musculature has a tendon that runs down to the lower part of the chest, and is slightly curved from top to bottom, reaching the transverse fibers of the internal chest muscles to the mid-thoracic area. Around the thin pectoralis there are also blood and lymphatic vessels, ligaments of the thoracic diaphragm and latissimus muscles. The sternum is surrounded by an internal oblique of intercutaneous fascia, which helps maintain a light gas sac. Chest muscles
