Shoulder blades

Generality

The scapula is the even bone, located postero-lateral to the rib cage, which articulates the trunk to the upper limb of each side of the human body.

Mainly flat and triangular in shape, it has some anatomical elements, such as the acromion, the coracoid process and the glenoid cavity, which make it a particular and unique bone of its kind.
The shoulder blades have two main functions: to hook the head of the humerus to their glenoid cavity, thus forming the so-called glenohumeral joint (or shoulder joint), and to insert the initial extremities of the muscles making up the rotator cuff.
Like any bone in the human skeleton, the shoulder blade can fracture. Fractures of the scapula are very rare events, usually resulting from severe trauma to the chest.

What is the Scapula

The scapula is the even bone, located posterolateral to the rib cage, which connects the trunk to the upper limb on each side of the body.
The junction point between the trunk and the upper limb (arm) is the so-called glenohumeral joint.
The glenohumeral joint - better known as the shoulder joint - involves the lateral margin of the scapula and the head of the humerus. The humerus is the bone in the arm and the head of the humerus is a medially oriented bone projection.
The scapula is a triangular flat bone, which occupies a certain position by virtue of its union with the clavicle. Numerous muscles of the shoulder-upper limb anatomical tract are placed on it.
