| |Deltoid muscle
| |
| |
| |
| * The anterior or clavicular fibers arises from most of the anterior border and upper surface of the lateral third of the clavicle.
| |
| * Lateral or acromial fibers arise from the superior surface of the acromion process of the scapula.
| |
| * Posterior or spinal fibers arise from the lower lip of the posterior border of the spine of the scapula.
| |
| |Middle of the lateral aspect of the shaft of the humerus
| |
| |Axillary nerve
| |
| |
| |
| * The prime mover of arm abduction along the frontal plane.
| |
| * The arm must be medially rotated for the deltoid to have maximum effect.
| |
| ** This makes the deltoid an antagonist muscle of the pectoralis major and latissimus dorsi ''during arm adduction''.

| * Anterior surface of the sternal half of the clavicle.
| |
| * Half of the anterior surface of the sternum.
| |
| * The cartilages of all the true ribs, with the exception, frequently, of the first or seventh.
| |
| * Aponeurosis of the abdominal external oblique muscle.
| |
| |Bicipital groove (intertubercular sulcus) of the humerus
| |
