The scapulae can move in six directions and each movement is produced by specific, primary muscles. A helpful way to learn anatomy is to move and mimic the actions for the muscles you are learning that week.
Muscles which produce Downward Rotation of the scapula. Levator Scapulae. Rhomboid Major. Rhomboid Minor. Latissimus Dorsi. Pectoralis Major (lower part) Pectoralis Minor.
The movement of the scapula can be described by rotations in relation to the thorax. The scapula moves around a dorso-ventral axis, resulting in a rotation in the frontal plane. In this movement the glenoid cavity is turned cranially (upward rotation) or caudally (downward rotation).
The dynamic stabilisers of the shoulder complex include the rotator cuff muscles, the deltoid, and the scapular muscles, which control scapulohumeral rhythm. For optimal shoulder stabilisation, the dynamic stabilisers must function efficiently and synergistically.
Downward rotation of the scapula occurs as the arm is returned to the side from a raised position. The motion is described similar to upward rotation, except that the clavicle depresses at the SC joint and the scapula downwardly rotates at the AC joint.
So what are the best individual exercises to accomplish these strengthening goals? We’ve broken them down by the specific muscles they target: Serratus Anterior. Push-up with plus; Dynamic hug; Serratus punch at 120 degrees flexion; Dynamic Hug. Lower Trapezius. Prone full can; Prone external rotation at 90 degrees abduction; Prone horizontal ...
These muscles attach the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint. The extrinsic muscles include the triceps, biceps, and deltoid. The third group of muscles includes the levator scapulae, trapezius, rhomboids, and serratus anterior.
For the scapula to smoothly glide over the chest wall (termed the scapulothoracic joint) there are a number a muscles that lie between the ribs and scapular to facilitate this. Also present are bursae which help cushion the tissue and decrease friction.
Studies using both motion tracking systems and indwelling bone pins have demonstrated that total scapular movement is a composite of motions (rotations around axes) and translations (sliding along a surface). 1, 2, 3, 4. The three observable rotary motions are: Upward/downward rotation around an axis perpendicular to the scapular body.
The scapula is a large, triangular bone that shapes the shoulder. Its function and location require that it attach to a number of muscles, ligaments, and tendons, including those of the rotator cuff. Conditions affecting the scapula arise from injury, illness, and congenital deformity.
