musculus pectoralis minor
Noun: A small, thin, triangular skeletal muscle situated beneath the larger pectoralis major muscle in the chest. Its primary functions are to draw the scapula (shoulder blade) downward and forward (depression and protraction) and to assist in raising the ribs during forced inhalation.
This term is used in specific, technical contexts such as anatomy, medicine, physical therapy, and fitness. It is not used in everyday conversation.
Examples: * The musculus pectoralis minor originates from the third, fourth, and fifth ribs and inserts into the coracoid process of the scapula. * A tight musculus pectoralis minor can contribute to rounded shoulders and poor posture. * The surgeon carefully identified the musculus pectoralis minor during the reconstructive procedure.
- In clinical assessments, the length and tension of the musculus pectoralis minor are often evaluated to diagnose shoulder impingement syndromes or thoracic outlet syndrome.
- In strength training, specific stretching exercises target the musculus pectoralis minor to improve shoulder mobility.
- Pectoralis minor: The most common abbreviated form of the full Latin term.
- Minor pectoral muscle: A direct English translation.
