 Deltoid muscle - Wikipedia, the free encyclopedia
The deltoid muscle is the muscle forming the rounded contour of the human shoulder.
From this extensive origin the fibers converge toward their insertion, the middle passing vertically, the anterior obliquely backward and lateralward, the posterior obliquely forward and lateralward; they unite in a thick tendon, which is inserted into the V-shaped deltoid tubercle on the middle of the lateral aspect of the shaft of the humerus.
The middle fibres of the muscle arise in a bipenniform manner (like a bird's feather) from the sides of the tendinous intersections, generally four in number, which are attached above to the acromion and pass downward parallel to one another in the substance of the muscle.

 Overview
Good shoulder function was not obtained unless the biceps and deltoid muscles began to contract by 3 months and had normal strength by 5 months.
Improvement of muscle strength as assessed by neurologic examination is the most sensitive test of which infants will recover without surgical intervention.
Even in children who have made a good spontaneous recovery, the weak deltoid muscle and consequent limitation in raising and rotating the shoulder are common persistent disabilities.

Deltoid fibrosis is a muscle disorder marked by intramuscular fibrous bands within the substance of the deltoid muscle.
Deltoid fibrosis has been associated with fibrous contractures of the gluteal and quadriceps muscles and is likely a similar process.
Therefore, deltoid contracture in the young patient should be treated surgically when the patient is at an age that allows spontaneous correction of the bony deformity with growth.

Since many programs emphasize more of the anterior and lateral deltoids, sticking in traps with the deltoids acts like more exercises to work the posterior deltoid so that it too is given a good workout, which is true for my program.
The deltoids respond very well to volumizing movements - especially when you squeeze out rep after rep, causing more blood to be transported to the muscle, which conclusively kick starts the growth process in the muscle.
The deltoids are a relatively small muscle group; therefore, they don't require as much time between sets as a larger muscle group such as the legs.
