Clavicle

Clavicle - The supporting element of our body

The collarbones are the paired long bones of the spinal column that lie on the front surface of the chest and connect the scapula to the sternum. The collarbone is curved, surrounded by muscle tissue and creates gaps for the passage of blood vessels and nerves. The collarbones perform important functions in the human body, so the slightest damage requires careful diagnosis and urgent treatment.

Functional significance of the clavicle

The collarbone is the supporting element of the chest walls and connects the upper limbs to the ribs. However, its main task is to connect the shoulder blades, providing support for the shoulder joint. It also maintains a straight back position. On both sides of the clavicles there are special processes - acromions. They join the humerus through the tubercles of the same name.

When the shoulder flexes, the joint begins to rotate around its axis, and the collarbone completely retains its structure. The collarbones also act as conductors for blood vessels, blood and lymph. In front there is a small tubercle - the sternal end. In the back of the collarbone there is a depression in which lies a layer of pleura that covers the lungs and descends as they move. This is also where the nerve passes, which is responsible for supplying nutrients to the muscle around the collarbone. In the area of ​​each end of the clavicle there are one or several joints, like cylindrical block-shaped ones, connecting to the shoulder blades. On the frontal plane, each of them forms a connection of four bones. Ligaments and numerous vessels provide general strengthening of these articular joints. Anatomically, the clavicles have three surfaces: * Anterior * Superior * Posterior _ Anterior surface
