In the CON, pectoralis minor

The common subscapular trunk descends medial to the axillary vein and medial root of the median nerve, resting on ventral surface of subscapular muscle under cover of pectoralis minor
The pectoralis major appears thick, and overlies pectoralis minor
, with a strongly reflective hyperechogenic perimysium often separating the two muscles.
Muscle flexibility of the pectoralis minor
was tested by having the subject lie supine on a firm table with knees bent and the lumbar spine flat on the table.
Because the staging of lymph node involvement is such an important aspect of breast cancer staging, it has been divided into three distinct levels: Level I lymph nodes are lateral to the lateral margin of the pectoralis major muscle and extend down into the tail of the breast; Level II lymph nodes are beneath the pectoralis minor
muscle; and Level III lymph nodes are medial and superior to the pectoralis minor
In his original description titled "Deficiency of the pectoral muscles," he specifically noted absence of the stern costal portion of the pectoralis major muscle with an intact clavicular origin, absence of the pectoralis minor
muscle, and hypoplastic serratus and external oblique muscles.
Palpation revealed tenderness and hypertonicity of the right anterior scalene, upper trapezius, levator scapulae, rhomboids, infraspinatus, subscapularis, pectoralis minor
, corocobrachialis, pronator teres and flexor carpi ulnaris muscles.
The weight of pectoralis major and pectoralis minor
muscles, which were dissected for sensory analysis, was also recorded and included as lean in carcass composition.
He was treated with physical therapy for a torn pectoralis minor
muscle that was thought to have caused the thrombosis, and postural correction.
The course of the axillary artery is anatomically divided into three parts by the pectoralis minor
In my clinical experience treating TOS, this technique has worked very well when applied to the upper trapezius, scalenes, the subclavius, and the pectoralis minor
Damage can express itself not only in soreness, but in headaches when the rhomboids, trapezius, subclavius and pectoralis minor
