Supraclavicular Fossa Minor

The supraclavicular fossa is a depression on the anterior surface of the clavicle, which is located between the clavicular and sternoclavicular ligaments. It has the shape of a triangle, the base of which is directed downward and posteriorly. The supraclavicular fossa is the attachment site for muscles that are involved in movement of the shoulder girdle, such as the pectoralis major, pectoralis minor, and serratus anterior.

The supraclavicular fossa can be used to determine the level of injury to the shoulder joint. If the supraclavicular fossa is damaged, it may indicate a muscle or tendon tear in the shoulder joint. In addition, the supraclavicular fossa can also be used in the diagnosis of heart diseases such as myocardial infarction.

Thus, the supraclavicular fossa plays an important role in the functioning of the shoulder girdle and can be useful in diagnosing various diseases.

The supraclavicular fossa minor is an anatomical formation that is located on the anterior wall of the chest. It is formed between the collarbone and the pectoralis major muscle. Its bottom cannot be palpated in all cases, since the upper part of the heart, large vessels, and the scalene muscle are often projected onto it.

The superficial region of the lesser epigastric triangle is the entrance to the supraclavicular fossa. Bisection of the angles when viewed from the side at right angles to the anterior plane of the body crosses the sternum and subclavian bones and provides the beginning of the thoracodorsal triangle. The sterno-clavicle gives up 1/4 of its elevation. It ends at the ulnar edge of the clavicle. The extensor pronator is associated with the scapula and semitendinosus muscle. The pronator quadratus connects to the quadratus forearm muscle. Both the base and the anterior margin rotate around the transverse process of C6. Middle supinator muscles
