In reference to the muscles of the thoracic wall, the intercostal nerves and vessels run posterior to the internal intercostal muscles: therefore, they are generally covered on the inside by the parietal pleura, except when they are covered by the innermost intercostal muscles, innermost intercostal membrane, subcostal muscles or the transversus thoracis muscle.
The upper five or six anterior intercostal arteries are branches of the internal thoracic artery (anterior intercostal branches of internal thoracic artery).The internal thoracic artery then divides into its two terminal branches, one of which - the musculophrenic artery - proceeds to issue anterior intercostal arteries to the remaining 6th, 7th, and 9th intercostal spaces; these diminish in ...
To better expose the floor of the triangle up of the posterior thoracic wall in the 6th and 7th intercostal space, a patient is asked to fold their arms across their chest, laterally rotating the scapulae, while bending forward at the trunk, somewhat resembling the fetal position. The triangle of auscultation can be used as a surgical approach ...
The intercostal lymph nodes (intercostal glands) occupy the posterior parts of the intercostal spaces, in relation to the intercostal vessels. They receive the deep lymphatics from the postero-lateral aspect of the chest ; some of these vessels are interrupted by small lateral intercostal glands.
The intercostal veins are a group of veins which drain the area between the ribs ("costae"), called the intercostal space. They can be divided as follows: Anterior intercostal veins; Posterior intercostal veins. Posterior intercost vein that drain into the Supreme intercostal vein - 1st intercostal space
The apex beat is found approximately in the fifth left intercostal space in the mid-clavicular line. It can be impalpable for a variety of reasons including obesity, emphysema, effusion and rarely dextrocardia. The apex beat is assessed for size, amplitude, location, impulse and duration.

The endothoracic fascia is deep to the intercostal space. The endothoracic fascia is the layer of loose connective tissue deep to the intercostal spaces and ribs, separating these structures from the underlying pleura. This fascial layer is the outermost membrane of the thoracic cavity. The endothoracic fascia contains variable amounts of fat.
