Pectoral region and axilla
Left axilla (continued); general view of contents; subclavius muscle
The pectoralis major and minor muscles have cervical been resected. The deltoid muscle has been divided close to its origin (10) and reflected laterally. The subclavius muscle (5) has been exposed by removal of the coracoclavicular fascia. The sternocleidomastoid and trapezius muscles have been resected and the external layer of cervical fascia removed. Several lymphatic trunks (20) enter the lateral group of axillary lymph nodes (22) from the arm. Some of the axillary nodes have been removed.
