Mechanical methods are among the oldest and most important approaches used for induction of labour (4, 5). They are indicated for labour induction in prolonged pregnancies, diabetic and hypertensive disorders of pregnancy and premature rupture of membranes.
Shoulder Adductor Muscles? What are the muscles involved in shoulder elevation? The muscles involved in elevating the shoulder girdle (e.g. shrugging your shoulders) are the upper fibers of trapezius, levator scapulae, rhomboid major and rhomboid minor.
Function. The pectoralis major muscle is the most important muscle for the adduction and anteversion of the shoulder joint which is why it is also known as the âbreaststroke muscleâ. It rotates the upper arm outwards and makes a powerful stroke movement (retroversion) when the arms are elevated (e.g. in wood-chopping).he pectoralis major muscle (green highlighted on the picture) is a strong, fan-shaped muscle of the shoulder joint. It decisively shapes the surface anatomy of the breast. Furthermore it participates in forming the anterior wall of the axilla.
