Shoulder Workings

Little by little I'm going to go presented the different regions of the body to serve to frame the most common injuries that occur in the sport, of which already ire speaking.I will begin with the anatomy of the shoulder since it is a joint with great mobility, which makes it very sensitive and prone to injury in the sport.
The anatomy of the shoulder is quite complicated. It is not a single link, but a complex joint, where several joints work in a coordinated manner to allow a wide range of movements and very broad in many directions. What I'm going to present here is a very small summary. The inaccuracies and tlb. which left me out, but it would be eternal. You can use the comments to ask for clarifications or make refinements.
Bone elements from the shoulder joint
Good, this is the images more sencillitas. Just the bones and ligaments (also some muscle tendons).  Is the left shoulder when viewed from the front. We emphasize:
Shoulder (bones and ligaments)

Clavicle: so to speak, joins the sternum to the shoulder.Specifically the clavicle articulates with the acromion, which is a highlight of the scapula bone.is at the top of the image.
Scapula: The shoulder blade that we all know, with a triangular shape. As I said, has a relief called acromion bone that articulates with the collarbone. To the left of the image. As we know, is located in the back.
Humerus: The bone that runs from the shoulder to the elbow. To the right in the image. To join these bones, the ligaments are, that you can see from the image. In addition, there are other elements, such as joint capsule, bursas… but we're not going to get there, that we did not.
We will now look at the musculature, which is the one that has more risk of injury.
Main muscles that move the shoulder
in this view of the left shoulder from behind, we can appreciate the muscles:
Shoulder

teres major (teres major).
Rotator Cuff: Receive this designation the supraspinatus muscles (supraspinatus, infraspinatus (infraspinatus), teres minor (teres minor and subscapularis (not shown in the picture, is hidden underneath the scapula).  These four muscles inserted more or less in the region of the head of the humerus. They are mostly rotation movements and is responsible for the important role of giving stability to the joint. By its position and anatomical and functional characteristics (long tendons that pass between bony ridges…) have a certain predisposition injury in unnatural postures, repetitive movements… they deserve an article. Calm, that will come.
Deltoid (deltoideus): Very famous. It is the muscle that forms the "ball of the shoulder".

Example of movement: Abduction (separation) of shoulder.

Conclusion
In conclusion and tell you that the shoulder, to be the most mobile joint of the body, is also very unstable. Hence the importance of the training of the muscles that are responsible for determining the shoulder. In addition, by their anatomical characteristics, the muscles are forced to pass through narrow channels, where it is easy to suffer from compression and tears if efforts are made very large or very long in incorrect positions. For this reason it is essential that extremeis precautions at the time of train shoulders you pay close attention and always a good realization of the movement. We will continue with the shoulder in forthcoming articles. Here I am waiting for you.
