Scapula

clavicle (anterior fibers), the acromion of the scapula (lateral fibers) and the spine of the scapula (posterior fibers). All the fibers merge on the deltoid tuberosity of the humerus.The anterior fibers flex and rotate the humerus medially. The lateral fibers abduct the humerus. The posterior fibers extend and laterally…

that exercises strengthening the scapula stabilising muscles (serratus anterior and trapezius muscles) have shown to be beneficial for overarm athletes. By building up the dynamic stability of these muscles it may prevent them from being overstretched during the serving…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

Conservative treatment for scapular dyskinesia includes manual therapy, therapeutic exercise, neuromuscular reeducation and therapeutic activities. The importance of warming-up muscles before physical therapy has been confirmed to decrease the chance of injury and increase performance.14 Kelly et al.,15 suggests that using an upper body ergometer for 5 minutes at 65-85% of age predicted max heart rate is a sufficient warm-up before physical therapy. In a study by Naidu and Ramteka16, grade IV…

The two main neck muscles are the sternocleidomastoid and the trapezius, and are responsible for the gross motor movement in the muscular system of the head, neck and shoulders. The sternocleidomastoid muscle is a paired muscle, located at the front and on each side of the neck. It is one of the largest and most superficial cervical muscles. The primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck. The trapezius is one of the biggest shoulder and…

range of motion for positioning the upper extremity in space. The shoulder girdle also provides power and support for the upper extremity throughout and at the extremes of the range of motion. (19) The shoulder girdle includes three bones (scapula, clavicle, and proximal humerus), three joints (glenohumeral, acromioclavicular and sternoclavicular), an additional articulation (scapulothoracic) and some 17 musculotendinous units. These individual elements function in a synchronous…

sides of the body on the shoulder joints for horizontal abduction and internal rotation while putting all force into the pole to push off into the air. The Serratus anterior on the left shoulder girdle draws the scapula upward slightly, then it draws the medial border of the right scapula away from the vertebrae as the vaulter lifts themselves up. The pole plant is essential as well because without a properly executed pole plant a vaulter can fail at clearing the bar and even injure…

humerus serves as a insertion and origination point for numerous muscles, such as the pectoralis major and the deltoid. Its primary function is the facilitation of movement and support for the arm . In chickens, the humerus, along with the coracoid and scapula, forms the shoulder. The humerus also joins the radius and ulna to form the elbow. These allow for movement of the arm and are extremely lightweight to allow for flight. In humans, the radius and ulna are two bones located in the superior…
