Deltoideus Origin the anterior border and upper surface of the lateral third of the clavicle, acromion, spine of the scapula Insertion deltoid tuberosity of humerus Artery thoracoacromial artery, anterior and posterior humeral circumflex artery Nerve Axillary nerve Actions shoulder abduction, flexion and extension Antagonist Latissimus dorsi
As the deltoid muscle abducts the arm, it also elevates the humerus, which butts against the acromion of the scapula and can go no further. turn your palm upward and you are able to complete the range of motion overhead. The infraspinatus and the teres minor function to externally rotate the arm and, along with the supraspinatus, draw the humeral head inward and down, thus clearing the acromion and allowing the arm to abduct to 120 degrees
“Shoulder” is a general term covering a broad group of muscles in the upper extremity.

Learn about AC joint sprain taping. The acromioclavicular joint (AC Joint) is found at the top of the shoulder and forms the junction between the acromion on the scapula (shoulder blade) and the clavicle (collar bone). This joint forms the highest point of the shoulder. The AC joint functions to allow the individual to raise their arm above their head. #Health #Sport

Shoulder Joint is located in the space between the acromion and the humerus. Crooked Pond is found at the lateral edge of the elbow crease.
Good Scapulo-humeral Rhythm illustration. To achieve the correct position, you need to use your mid and lower trapezius muscles to retract the shoulder and pull the scapula down medially. However, it is also important not to dip the acromion, so your upper trapezius and serratus anterior muscle also play an important scapular positioning role.
