"The pectoralis minor muscle is a muscle of the pectoral region lying deep to and completely covered by the pectoralis major muscle. It is an important anatomical landmark in two senses:"
"origin: anterior 3rd-5th ribs near the costal cartilage"
"insertion: medial and upper aspect of the coracoid process of the scapula"
"innervation: medial and lateral pectoral nerves (from nerve roots C6-C8)"
"arterial supply: thoracoacromial, superior thoracic and lateral thoracic arteries"
"pre-fixed origin: ribs 2-4"
"post-fixed origin: ribs 4-6"
"innervation: medial and lateral pectoral nerves (from nerve roots C6-C8)"
