Pectoralis minor

The pectoralis minor muscle is a much larger than the Pectoralis major, and is divided into several parts. However, most of its anterior broder is covered by the pectoralis major.

Xiphihumeralis

The most posterior, flat, thin, and long strip of pectoral muscle is the Xiphihumeralis. It is a band of parallel fibers.
