The human Body is a coordinated system. With the right device, its parts, performs all the functions necessary for life. The main pillar of the body is the skeleton. The following are considered the most important component of joints and ligaments. Because of these formations people are able to make any movement.
The Joints of the upper extremity are numerous. Most of them observed in the hands and fingers. However, in order to bring the entire upper limb in motion, takes the three main joints: shoulder, elbow and wrist. The anatomy of these complex entities because they are composed of many parts (bones, ligaments, muscles, nerves and vessels).
Anatomy of the elbow joint, shoulder joint, like the wrist, is a coordinated mechanism that has multiple components. Each of these entities is important. Only through proper structure of the entire joint, it can carry out its functions. Anomalies or diseases of the bone or ligaments leading to movement disorders of the upper limb. The same applies to abnormalities of the blood vessels and nerves.
Anatomy of the elbow joint includes 3 bones, several ligaments, capsule and muscles. For the functioning of each of these entities should blood supply and innervation. Like any part of the body, has blood vessels and nerves and the elbow joint.
Anatomy it created so all components together performed a single function-movement of the limb. In General, the term “elbow” includes not only the joint but also the forearm. Thanks to the coordinated work of these entities, he can perform the following functions:

Anatomy of the elbow difficult, as it is of complex joints. Primarily this is because it is composed of 3 bones. In addition, each of them connected by small joints. They are all under a special capsule – bag.
Clearly consider the education to be in a special Atlas. There you can see all the joints that comprise the elbow joint. Anatomy (photo in Atlas, to help you better understand it) this formation is represented there in various angles and sections that it is clear to all his device.
Bone, a part of the described joint and located at the top (proximal) called the humerus. It starts from the scapular depression and ending at the elbow. Refers to the tubular bones of the skeleton. When viewed in cross-section, we can see that the lower part has the shape of a triangle. This area includes the articular surface. Its middle part is connected with the ulna and forms a small joint. It is called – preselective articulation.
The Side (lateral) is the connection with the radial bone. There is also a joint called the brachioradialis joint. Two dice included in the elbow joint with the distal part, also connected with each other. They form the third articulation – proximal radioulnar. All together these reasons education is covered by the bag.
In Addition to bones, anatomy of the elbow joint includes the ligaments. They are the connective tissue fibers, which are also required to implement the motion. Here are the following bundles:
Muscles – the organs by which man can perform the stretching and bending of limbs. Anatomy of the elbow joint includes the striated muscles, although the muscles are not part of the joint. Nevertheless, they are indispensable, as without them, the joint cannot carry out its function. Muscles located in the proximal and distal region, i.e. above and below the joint. Among them:
Thanks to all of them the upper limb performs movements. Therefore, they should also be attributed to the anatomical structures of the elbow. Because the muscles involved in the movement of the forearm.
All anatomical structures of the elbow joint are enclosed in a so-called bag. It consists of a synovial membrane, which is located inside liquid. In the cavity of the bag includes all 3 joints of the bones. As a result, the formation of a joint-the elbow.
In turn, each of the three small joints is also enclosed in the bag. By the way, this sheath is present in all joints of our body. It protects bones and ligaments from damage. And the liquid, which is inside the bag, which is required for lubrication of the articular surfaces. Thanks to synovial fluid, the bones and joints are not damaged in the collision (during the movement).
To all entities included in the elbow functioned needed blood flow. It comes with three large vessels. Among them are: humerus, ulna and radius of the artery. Each of them in turn, has ramifications. In General, the elbow 8 is supplied by arteries branching from the main three. Some of them provides oxygen to muscles. Supply blood to other bones and joints.
All of these vessels form a network-to-end anastomosis. As a result of the defeat of one of them, the blood still goes to the body. However, the anastomoses between the arteries do not always help the wounded. This is because bleeding from the network of blood vessels difficult to stop.
All the arteries located on the surface of bag replacement. Thanks to them, all the joints is fed with oxygen.
Venous system spread throughout the body. Is no exception and the anatomy of the elbow joint. Venous outflow from the entities that compose the articulation, is the eponymous (arteries) vessels. That is the blood rich in carbon dioxide, from the joint returns to a cardiac system. There are the following vessels, engaged in the outflow:
These vessels carried the blood into pools three main veins. They are called the same way as the arteries: radial, ulnar and shoulder. All of them fall into the large axillary vein.
The Lymphatic system consists of vessels and ducts. Also in the body there are several major groups of peripheral nodes. Among them: axillary, elbow, inguinal, and other clusters of lymphoid tissue. In addition, there are small nodes.
The lymph drainage is through deep vessels. They are next to the arteries and veins of the upper limb. Lymphatic vessels of the hands...
