Muscles and Fasciae of the Trunk
Fasciae of the Thorax

According to the most common Classification, the Fascia of the chest includes the superficial, pectoral, clavipectoral, and endothoracic fasciae.

The superficial fascia (fascia superficialis) of the chest is poorly developed.

The pectoral fascia (fascia pectoralis) covers the pectoralis major Muscle. Superiorly, it fuses with the periosteum of the clavicle; medially, with the periosteum of the Sternum; laterally, it continues into the axillary fascia; and inferiorly, it transitions into the thoracic fascia.

The clavipectoral fascia (fascia clavipectoralis) covers the pectoralis minor and subclavius Muscles. Superiorly, it attaches to the inferior border of the clavicle and the coracoid process of the scapula. Inferiorly, it merges with the pectoral fascia.

The thoracic fascia (fascia thoracica) covers the external intercostal muscles and Ribs.

The endothoracic fascia (fascia endothoracica) lines the internal surface of the thoracic walls.
