What is another word for smaller pectoral muscle?
Pronunciation: [smˈɔːlə pˈɛktəɹə͡l mˈʌsə͡l] (IPA) 
The pectoral muscle is a large muscle located in the chest region, comprising of two parts, the larger and the smaller one. The smaller pectoral muscle is also known as the pectoralis minor or the minor chest muscle. It is situated underneath the larger pectoral muscle and is responsible for the movement of the scapula or shoulder blade. Other synonyms for the smaller pectoral muscle include the lesser pectoral muscle, the subclavius muscle, and the thoracic muscle. Although it is smaller in size, it has an important role in shoulder and arm movements and maintaining good posture. Strengthening exercises targeting this muscle can help prevent shoulder injuries and improve overall upper body strength.
