Supraspinatus muscle (first 20 degrees), Medial Deltoid (beyond 20 degrees). This is the reason why many weight lifters, performing Lateral Shoulder Raises 'bounce' or 'flick' the weight at the beginning of the movement when fatigued or the load is too heavy - to circumvent the weak suprasinatus

What Actions of the shoulder girdle?
abduction, adduction,rotation, elevation
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.
What part of the body are the deltiod muscles in?
The deltoid muscles are a part of the shoulder girdle.
What muscles are used to depress the shoulder girdle?
The muscles used to depress the shoulder girdle include the latissimus dorsi, pectoralis minor, and lower trapezius. These muscles work together to pull the shoulders down and stabilize the shoulder blades.
The scapulae and the clavicles together form the?
shoulder girdle, which provides attachment points for the muscles that move the arms and shoulders.
What is the Main function of shoulder blade?
The shoulder girdle(pectoral girdle) functions as a point of flexibility. The clavicle, scapula and the humerus articulate in the girdle.
What is the posterior portion of pectoral girdle?
the scapula (shoulder blade) and the clavicle (collarbone) make up the pectoral girdle. Each upper limb articulates with the trunk at the pectoral girdle, or shoulder girdle The pectoral girdle consists of two broar, flat scapulae and the two slender, curved clavicles. Each clavicle articulates with the manubrium of the sternum; these are the only direct connections between the pectoral girdle and the axial skeleton. Skeletal muscles support and position each scapula, which has no bony or ligamentous connections to the thoracic cage.
Movements of the thigh are accomplished by muscles anchored to the pelvic girdle?
Yes, muscles such as the quadriceps, hamstrings, adductors, and abductors attach to the pelvic girdle and are responsible for moving the thigh. These muscles work together to allow for various movements such as flexion, extension, abduction, adduction, and rotation of the thigh.
What do muscles that act on the shoulder originate?
Most originate on the Scapula (the Shoulder Girdle), not all though. The Pectoralis Major & Minor and the Latissimus Dorsi do not.
What is the superficial muscles of the upper back and shoulder of a frog?
The superficial muscles of the upper back and shoulder of a frog include the trapezius, deltoid, and latissimus dorsi muscles. These muscles work together to provide support and movement for the frog's forelimbs and shoulder girdle.
What muscles and bones are used to pick up an object?
The biceps brachii, deltoid (anterior portion), brachioradialis and brachialis are used when you lift a glass to drink from it. The shoulder girdle muscles are also involved, including the trapezeus muscle across the top of your back. Chest muscles (muscles of respiration) are secondarily involved.
What division of the skeleton consists of the bones of the shoulder girdle hip and extremities?
The appendicular skeleton consists of the bones of the shoulder girdle, hip, and extremities. These bones provide support and attachment points for muscles that allow for movement and mobility.
